1. Overview: Open-Source AI and How to Read Documentation Effectively
The six open-source repositories below are currently the most talked about for monetizing AI, and all of them are free to download and use. This guide covers the critical parts that introductory tutorials often skip: how to install them, who to sell to, how to get paid, and where you are most likely to lose all your hard work.
I wrote this for people who have never touched a line of code. Every technical term is explained the very first time it appears. If you know how to open a browser and copy a line of text, you can read and understand this entire guide.
And there is one thing we want to state clearly right from the beginning: we opened and reviewed the license for each of these six repositories individually, and found two critical details that most English content gets wrong. One repository is widely assumed to be free for commercial use when it actually is not. Another repository is cited with prices inflated four times higher than the real cost. Both cases are detailed in this guide, complete with links so you can verify them for yourself.
How to read this guide effectively: Do not try to read everything before taking action. Read Part 1 (mandatory—it teaches you how to verify licenses yourself, which is the most critical skill here), then jump straight to the one repository that aligns closest with what you are doing right now. Save the remaining five for next month. The six concepts below appear throughout the entire guide. Click on any unfamiliar term to open its explanation, or skip ahead if you already know it. All six repositories are free to download. The actual expenses you will incur are API fees (ranging from roughly a few dollars to a couple of dozen dollars per month when starting out), and for repository #4, the cost of renting a cloud GPU machine. I have clearly detailed the estimated costs in each section. All six repositories follow the exact same installation flow: install Docker to download the repository to fill in the API key to run a single command to open your browser. Learn it once, and you can apply it to all six. Stuck at any step? Use the “Ask AI to Install” prompt in Part 11, paste it into Claude or ChatGPT, and it will ask what operating system you are running and guide you step-by-step. On GitHub, anyone can copy someone else’s repository into their own copy (known as a fork) and inject malicious code. Always verify repository URLs against the links provided in this guide, and prioritize repositories with a high number of stars (the star counter in the top-right corner of the GitHub page)—this is a clear sign that many people are actively using it. If you remember only one thing from this entire guide, make it this: a license is a legal document explicitly stating what you are permitted to do with that free software. It is located in a file named LICENSE right on the repository’s main GitHub page—you can click and read it without logging in. This is where money is lost, not in technical execution. Everyone is busy bragging about “six repositories to make money,” yet almost no one opens the LICENSE file to read it. Taking three minutes to read it gives you a competitive advantage that virtually the entire market ignores. Trap 1: “source-available” is not open source. Some software makes its source code visible and downloadable, but imposes restrictive conditions (for example: companies with more than 4 people must pay a license fee). Remotion in Part 5 is one such case. Trap 2: The license says one thing, but the author states another. A repository might be published under an Apache 2.0 license, but the project description states “for academic research only.” When the two contradict each other, the safest approach is to ask the author directly via the GitHub Issues tab and archive their written response. PersonaLive in Part 7 is an example of this. You will not find this section in any English-language video, but it determines whether your operations in Vietnam will run smoothly and legally. In 2025, the National Assembly passed two laws that directly impact the commercial distribution of AI-generated content. Article 44 of the Digital Technology Industry Law (Law No. 71/2025/QH15) stipulates: digital technology products generated by artificial intelligence must bear identifiable markers recognizable by either human users or automated machines. Furthermore, any AI system that interacts directly with humans must disclose to users that they are communicating with an AI.[1] The Artificial Intelligence Law 2025 has officially taken effect, establishing a dedicated legal framework for AI in Vietnam.[2] What this means for you: AI-generated content (especially synthetic imagery, video, and cloned human voices) must be clearly labeled, using both visible markers (on-screen text, watermarks, verbal disclaimers) and technical metadata embedded in the file. Correcting spelling errors or upscaling image resolution does not require labeling.[3] Add a simple disclosure line stating “Content created with AI assistance” in the video description, article footer, or during the opening seconds of a clip. It takes five seconds, and it turns legal exposure into a straightforward sentence. This is strictly mandatory for Repo 4 (AI avatars) and any video featuring synthetic voiceovers. For client work, proactively include this disclosure clause in your service contracts: state clearly that you leverage AI tools, and that the client is responsible for publishing with proper labeling. This keeps you fully compliant while projecting far greater professionalism than informal operators. This overview is compiled from legislative documents and reputable legal resources at the time of writing (September 2026) and does not constitute formal legal advice. Guiding decrees and detailed regulations continue to be enacted. If you plan to scale significantly or sign high-value contracts, consult a qualified attorney—the cost of a consultation is far cheaper than the cost of a single legal misstep.
2. Repo 1: AutoClip – Automatically Cut Short Clips from Podcasts and Long Videos
What It Can Do
You feed in a long video, a two-hour podcast, a livestream, or a lecture. AutoClip listens to the whole thing, cuts the video into segments based on content, scores them to see which parts are noteworthy, and then exports a series of short clips along with suggestions for grouping them into topic-based collections. It features a web interface for you to drag and drop to rearrange, and download them in bulk to your computer.[4]
The Business You Can Build on It
Monthly video clipping service. Clients send you their newly published long-form videos, and you deliver a batch of short clips ready for TikTok, Reels, and Shorts. Charge a flat monthly retainer.
The reason this business is viable isn’t about the technology; it’s because the raw material already exists. Podcasters, online educators, and YouTubers are all sitting on hundreds of hours of content that they know contains gold, but no one has the time to sit through and rewatch it all to find it.
Who to Sell to in Vietnam
- Vietnamese podcast channels that already have a back catalog of old episodes, which they almost never repurpose.
- Online course creators: they need promotional clips, and the primary raw material is the lectures they have already recorded.
- YouTube channels with videos over 20 minutes long: the longer the video, the more wasted segments there are.
- Businesses that frequently host webinars, talk shows, and internal training: each event yields hours of video sitting idle on their hard drives.
How to Install
Once it finishes running, open your browser and navigate to localhost:8000. If the git command returns a “command not found” error, you haven’t installed Git yet; head over to git-scm.com, download and install it, then try again. Or even faster: click the green Code > Download ZIP button directly on the GitHub page, extract the files, and the first step is complete.
The machine identifies clips that appear interesting to an AI model, not necessarily ones that people will actually watch. Those are two completely different things. Treat its output as a shortlist, not the final deliverable for clients. It gives you 30 clips; your job is to select the 5 that are truly worth posting. The value you sell to clients lies precisely in that curation step. Skip this, and you are selling empty volume that no one watches—and clients will realize this after just one month. An additional point specific to the Vietnamese market: speech recognition models still process Vietnamese worse than English, especially with regional accents and specialized terminology. Always proofread the subtitles before delivery. Monday: receive the client’s video, feed it into AutoClip, and let the machine run. Tuesday: review the 30 suggested clips, pick 5–8, and use the “Editorial Clip Selection” prompt in Section 11 for quick scoring. Wednesday: correct subtitles, add hardcoded captions, and export files. Thursday: write captions and hashtags (ready-made prompts provided). Friday: deliver to the client along with a brief explanation detailing why you selected these clips. That rationale is precisely what retains clients into the second month.
3. Warehouse 2: Remotion & Motion Canvas – Programmatic Bulk Video Generation
What it can do
Remotion allows you to create videos using code instead of dragging and dropping in video editing software. It might sound more complicated, but it unlocks something conventional editing software simply cannot do: feed data from a spreadsheet and generate hundreds of different videos, each with its own name, metrics, and images.
A simple example to picture: a real estate agency has 200 apartments for sale. With Remotion, you create one video template, and the machine automatically generates 200 individual videos for the 200 units—with the correct photos, prices, square footage, and addresses. Doing this manually would take weeks; this approach runs overnight.
Careers you can build on it
Mass video production that no human can do manually. Product showcase videos for e-commerce platforms, personalized sales pitch videos tailored to each client’s name, monthly data report videos for businesses, wrap-up videos for each student at a learning center. Many international companies have built real revenue on this exact foundation.
The most important part of the entire document: the Remotion license
This is where we need to correct some circulating misinformation. Many English sources state that “companies with 4 or more people must pay from $100 per month.” That figure is incorrect for most cases. I checked the official Remotion license and FAQ pages to cross-reference.[5]
| Who you are / What you do | How much you pay |
|---|---|
| Individual working solo | Free. And this is a true commercial license, not a trial version. You can take on paid work and still not owe a dime. |
| Non-profit organization | Free |
| For-profit company, 3 people or fewer | Free |
| For-profit company, 4 or more people, using it to edit videos in-house | $25/month per user (Remotion for Creators plan), with no minimum spend when purchasing this plan alone. |
| You build a product that automatically renders videos for other users, video editing apps, text-to-video tools, or batch video export systems | $0.01 per video render, minimum $100/month (Remotion for Automators plan). This does not depend on team size—even if you work completely solo, you still have to pay. |
The trap lies in how you deliver the deliverables to your client: For the exact same job, different delivery methods come with entirely different financial obligations. Remotion clarifies this on their FAQ page: If you only deliver the exported video file (the client receives an MP4 and never touches Remotion), only the headcount on your side counts. If you work solo, it’s completely free—even if the client is a corporation with thousands of employees. If the client owns or runs the Remotion project themselves (you hand over the source code for them to execute), the headcount of both parties is combined to evaluate the 4-person threshold. Whichever party ultimately owns the project is responsible for purchasing the license. In short: delivering exported files is cheap, delivering source code means someone has to pay. Decide this before quoting your price, and state it directly in the contract. There are two completely free alternatives with no headcount thresholds: Motion Canvas (MIT license) and HyperFrames (Apache 2.0 license). They have fewer features than Remotion, but if you plan to build an automated video rendering product, these are options worth considering from the start, as the Automators plan charges you even if you work solo.
4. Repository 3: OpenHands – Autonomous AI Software Engineer Handling Coding Tasks
What it can do
OpenHands is an autonomous AI software engineer. You describe the task in natural language, such as “fix the checkout page showing the wrong total” or “add an export customer list to Excel feature,” and it automatically opens the project’s source code, reads it, fixes it, and runs tests on its own. Unlike conventional code suggestion tools, it actually executes the work rather than just making suggestions.
Starting from the latest version, it can run directly on your local machine via a single Docker command and can connect to GitHub or Slack to receive tasks automatically.[6]
Careers you can build on it
Building small software for small businesses. This is a massive client segment in Vietnam: a retail shop, a medical clinic, or a manufacturing workshop needing custom management software, but hiring a full-time software engineer is out of reach. Typical gigs: internal management tools, connecting two existing software solutions, small applications, and maintaining legacy systems.
The most honest repository of the six, regarding the toll it takes on you: An AI programmer writing code that you cannot read is a ticking time bomb the moment a client relies on it. Because the person who gets called at 11 PM when the system goes down is you, not the AI. If you can read and understand the code it generates, this is genuine leverage: you can multiply your output several times over. If you can’t read it, you’re selling something you cannot support, and the first major incident will end your client relationship. The safe route in: take on narrow-scope, low-risk work with clear requirements where mistakes are immediately visible. Good examples: a data entry form, a report export tool, an automated file-renaming script. Examples to avoid when starting out: payment systems, client data storage, or anything where failure means losing real money.
Then open your browser to localhost:8000/canvas. On the first run, it will prompt you to select an AI model and paste your API key; pick whichever model you already have an account with. The version number 1.18.0 may be newer by the time you read this; check the repository’s GitHub page for the latest release. One: always make it work on a copy of the project—never let it modify a client’s live production system directly. Two: before delivering any lines of code to a client, run through the prompt “Pre-delivery Code Audit” in Section 11; it forces you to account for what every single block of code does, which is precisely how you catch the things you don’t yet understand.
5. Repository 4: PersonaLive – Real-Time AI Video Presenter and Streamer
What it can do
PersonaLive transforms a static portrait photo into an expressive, talking face in real time. The highlight lies in the words “real time”: it outputs continuous video with no length limit, meaning it can run an entire livestream session without a human sitting in front of the camera. This research work was presented at the CVPR 2026 scientific conference.[7]
Careers You Can Build on It
AI Brand Presenter: 24/7 live streaming channels, virtual presenters for brands looking for a consistent face without hiring actors per session, and mass-produced product introduction videos featuring the same presenter.
Three things you must do before accepting anyone’s money
Step 1: Read the license ourselves
This repository is licensed under Apache 2.0, which theoretically allows commercial use. However, the author’s description explicitly states “released for academic research purposes only.” These two statements contradict each other, and that contradiction is your risk, not the author’s.
This is very common with facial image generation models: most originate from university laboratories, and a research license does not automatically transform into a commercial license just because you are using it to make money. What you need to do: go to the Issues tab on the repository’s GitHub page, ask publicly whether you are allowed commercial use, and save the author’s response. If there is no clear answer, choose another tool with a clean license.
Step 2: Only animate faces you have the rights to use
There are only two safe scenarios: an AI-generated face that you own, or a real person who has signed a written consent form specifically for this purpose.
Animating someone else’s face without permission is the fastest route to legal trouble in this entire guide. In Vietnam, personal likeness is protected under Article 32 of the 2015 Civil Code: using another person’s image requires their consent, and commercial use requires compensation unless agreed otherwise. Individuals whose likeness is used without authorization have the right to demand removal and seek damages.
I have prepared a Vietnamese likeness and voice consent agreement template in Section 11—copy it, fill in the names, and get it signed before hitting record.
Step 3: Clearly disclose that this is AI
In Vietnam, as of March 1, 2026, labeling AI content that simulates real people is a legal requirement, no longer optional (see Part 3). Major social media platforms also require the declaration of photorealistic synthetic content.
A properly disclosed AI presenter is a legitimate product that many brands actively seek out. A concealed AI presenter violates platform policies and completely shatters audience trust the day the truth comes out—and it always comes out.
Regarding hardware, to be frank and save you time: this repository requires a graphics card with at least 12GB of VRAM to run. Standard office laptops and regular MacBooks cannot run it. Two practical paths in Vietnam: rent GPU cloud instances by the hour (hourly rental services, ideal for testing before committing), or start with an existing commercial AI avatar service to validate whether there is customer demand before considering self-hosting to cut costs. Do not buy a graphics card before securing your first paying customer.
6. Repo 5: RedInk – Multi-Platform Content Creation Automation
What It Can Do
You type in a single sentence, and RedInk returns a complete post formatted precisely for Xiaohongshu (also known as RED or RedNote—one of China’s largest social platforms, where users search for shopping, travel, and beauty recommendations): a page-by-page outline, a cover image with properly rendered typography, and a batch of content slides generated with a consistent visual style.[8]
A correction we need to make: Many English articles categorize RedInk as “download it and start a business right away.” That is incorrect. This repository uses the CC BY-NC-SA 4.0 license: the NC stands for Non-Commercial. You are allowed to use it for personal use, learning, and experimentation. If you want to use it to serve paying clients, the author requires you to reach out to arrange a separate commercial license agreement. This is not a minor detail. It is the difference between “a tool you can build a business on” and “a tool you need permission for first.” What you need to do is simple: open a GitHub Issue or email the author, clearly outline how you intend to use it commercially, and keep their written reply on record. Many open-source authors agree quickly, sometimes even for free. But you have to ask. The market opportunity here is real and very few people can serve it: producing content for brands looking to reach Chinese-speaking consumers. Almost no one in the Western creator space operates on Chinese platforms, so competition is scarce. But keep two things separate: the skill (creating content for the Chinese-speaking market) is real and does not depend on any specific repository. The tool (RedInk) is just a way to do it faster, and it comes with licensing constraints. If the author doesn’t grant a license, you can still do that work using other tools—just a bit slower. Use RedInk for yourself, non-commercially, to learn how a Xiaohongshu post is structured: what the cover looks like, what each slide says, and how the visuals are coordinated. You can take that knowledge to any tool you like, and that is what clients actually pay for—not the software.
7. Repository 6: MuMuAINovel – AI-Powered Novel Writing and Publishing Support
What It Can Do
A novel-writing assistant: generates outlines, manages characters, edits chapter by chapter, builds world-building lore, and maps out character relationship diagrams. Just plug in your OpenAI, Gemini, or Claude API key and you’re good to go.[9]
Three Things You Must Know Before Writing the First Word
Because the most common monetization direction for this repository is selling books on Amazon KDP (Amazon’s self-publishing platform), and Amazon has spent years building policies specifically against the practice of “mass book production.”
Step 1: Disclosing AI is mandatory, and you have nothing to lose by doing so
When you click publish, KDP asks upfront whether your book contains AI-generated content, including text, images (including cover art), and translations.[10]
Make sure to distinguish between these two concepts: “AI-generated” means AI created it based on your prompts (even if you heavily edited it afterward): you must disclose this. “AI-assisted” means you wrote it yourself and AI merely helped with editing, suggestions, or grammar checks: disclosure is not required.
The key takeaway: according to aggregated sources specializing in KDP, this disclosure is internal information; readers will not see it, and it does not affect your search ranking or royalties.[11] This means being honest costs you nothing, while hiding it is pure risk. There is simply no reason to hide it.
Step 2: There is a hard cap on volume: 3 new titles per day
Amazon limits regular accounts to publishing a maximum of 3 new titles per day. This limit was implemented specifically because of the wave of mass AI book publishing.[12] Updating existing books does not count toward this limit.
In other words: the “write as many books as possible” strategy runs straight into a rule designed precisely to block that very thing.
Step 3: Penalties have escalated to the account level
Amazon detects violations through multiple signals: writing patterns, book metadata, and publishing velocity. Previously, they only took down individual books; according to industry sources, in 2026 the penalties escalated to restricting and suspending entire accounts for repeat offenders.[11] Losing an account means losing your entire published catalog, and appealing is extremely difficult.
Notice the vicious cycle here: publishing speed is both the strategy and the signal they use to catch you. The more you lean into the “high-volume” approach, the more you set off the alarm bells yourself.
The version of this approach that actually survives: Use it to write faster, not to write more. Declare honestly because it costs nothing. And publish fewer books that are good enough for readers to actually review. Do the simple math: one book that sells steadily over three years easily beats thirty books taken down after two months—and those thirty books represent the exact playbook Amazon spent two years learning how to catch. For the Vietnamese market: consider writing Vietnamese-language books for domestic platforms, or niche English-language books on topics you genuinely understand. Both face far less competition than the generic, mass-produced content machines are churning out.
8. Comparison Table of 6 Repositories and Business Decision Matrix
Three things hold true for all six repositories, and understanding these three is more important than understanding any single repository.
Step 1: Code is free, but the craft is not in the code
Each of these repositories can be downloaded by thousands of people today. What you are actually selling is customer relationships, the taste to pick what is worth building, and the trust that you will deliver on time every single week. AI makes “being able to build” virtually free, which means “being able to build” is no longer an advantage.
Step 2: Money is lost in the rules of the game, not the technical side
Licensing in Remotion. Likeness rights and disclosure obligations in PersonaLive. Non-commercial licenses in RedInk. Platform policies on Xiaohongshu and KDP. AI labeling regulations in Vietnam.
Everyone currently creating content about these six repositories is competing on hype. The person who takes the time to read the licenses is competing on something no one else bothers to touch—and that is precisely what determines whether, six months from now, you have a career or a banned account.
Step 3: Pick one, don’t juggle all six
Each repository represents a real profession with real clients you need to find. The ones who make money are those who choose the one closest to what they already know and get straight to work.
| Repository | Commercial Use | Technical Difficulty | Choose if you… |
|---|---|---|---|
| AutoClip Short clip cutting |
MIT, fully permissible | Low | …are already familiar with content creation and know what makes a good clip. This is the easiest starting point. |
| Remotion Batch video creation |
Free for up to 3 people | Medium to High | …have clients who need hundreds of videos generated from a single dataset (real estate, e-commerce). |
| OpenHands Programming services |
MIT, fully permissible | Medium | …can read code. If not, skip this repository until you can. |
| PersonaLive AI Avatar / Presenter |
Must ask the author | High | …already have a powerful GPU or a budget for cloud rentals, and are willing to handle the legal aspects. |
| RedInk Xiaohongshu content |
Non-commercial | Low | …speak Chinese and can operate an account there. Ask the author for permission first. |
| MuMuAINovel Book writing |
GPL-3.0 | Low | …already write and want to write faster, not just generate bulk text. |
Not sure which one to choose? Answer one question: Over the past three months, what have you spent the most time doing hands-on? If it’s content creation, pick AutoClip. If it’s online sales or real estate, pick Remotion. If you’ve touched code even just to tweak a website, pick OpenHands. If it’s writing, pick MuMuAINovel. Choose based on what you already know, because the hardest part isn’t installing the software—it’s landing your first client, and you’ll find them fastest right where you’re already standing.
9. Set of 14 Battle-Tested Vietnamese Prompts for Immediate Application
This is the part we put the most effort into. A prompt is the text you paste into Claude, ChatGPT, or Gemini to get it to do exactly what you need. The fourteen prompts below are written entirely in Vietnamese, pre-contextualized for the Vietnamese market, and ready to use right away without edits: wherever your input is required, we have marked it with square brackets [like this].
Easiest Way to Use
- Find the prompt group associated with your selected repository from the list below.
- Click Copy in the top-right corner of the prompt box; for longer ones, click View full prompt to expand it first.
- Paste it into the chat box of Claude, ChatGPT, or Gemini.
- Replace the parts in [square brackets] with your information, then hit send.
Group 1. Warm-up: Installation and License Verification
Two foundational prompts: one guides you step-by-step through installing any GitHub repository specifically for the machine you are using, while the other reviews the license for you and directly answers whether you “can use it commercially or not.”
Act as a legal reviewer for a software project. Task: review the license of an open-source repository and answer me clearly, decisively, and without beating around the bush.
REPOSITORY TO REVIEW: [paste GitHub link]
WHAT I PLAN TO DO: [describe very specifically, e.g., "receive videos from clients, use this software to cut them into short clips, deliver MP4 files to clients, and charge 5 million VND per month"]
PLEASE READ AND ANSWER EXACTLY ACCORDING TO THE FOLLOWING FORMAT
1. ONE-LINE CONCLUSION
Choose exactly one of the four: PERMITTED / PERMITTED WITH CONDITIONS / PRIOR PERMISSION REQUIRED / NOT PERMITTED.
2. LICENSE NAME
Provide the exact name of the license and the link to the LICENSE file you reviewed.
3. RESTRICTIONS APPLIED TO ME
List as bullet points, one restriction per line, written in plain language. Pay special attention to:
- Is there a threshold based on company headcount?
- Is there usage-based pricing?
- Does it require me to open-source my code if I modify it?
- Does it prohibit commercial use?
- Does it require attributing the author anywhere?
4. CONFLICTS TO WATCH OUT FOR
Check if the README file, Disclaimer section, or project homepage mentions anything CONFLICTING with the LICENSE file. Many projects use a permissive license but add restrictive conditions elsewhere. If there is a contradiction, state it clearly and quote both sources verbatim.
5. WHAT I MUST DO BEFORE COLLECTING MONEY
A specific, ordered checklist of tasks. If author permission is required, draft a concise, polite email in English for me to send, clearly explaining my intended commercial use.
6. WHAT YOU ARE UNSURE ABOUT
Be upfront about any parts you are uncertain about and whether I should consult a lawyer or ask the author directly.
If you cannot access the contents of the LICENSE file, clearly state that it cannot be read instead of speculating.
