How to make faceless AI YouTube videos for free

On a faceless channel, your knowledge is the brand, not your face. So pick a niche where every video can explain something: a calculation, a comparison, a look behind the scenes.

Our example: the money math of small Indian businesses. A tea stall, a momos cart, a dhaba, a corner shop: how much they sell in a day, what it costs, and what the owner actually keeps.

Finding topics (free)

• YouTube's search bar: type "tea stall business" and note the suggestions that drop down. Those are the exact phrases people search for.
• Similar channels: sort their videos by "Popular". Don't copy topics; learn what viewers respond to.
• Comments: viewers' questions are your next video ideas.

Topics to stay away from

• Stock, crypto or loan tips, and "get rich quick" content
• Firm medical, legal or tax advice (an AI voice posing as an expert is risky under YouTube's rules)
• Naming and judging real private people
• Politics and religion

The free versions of Google AI Studio (Gemini) or ChatGPT are enough. What makes the difference is the prompt. Copy the one below and replace the parts in [brackets].

You are a YouTube Shorts scriptwriter.
Topic: [one day of earnings at a tea stall]
Language: [Hindi, in Devanagari script]
Length: 45–55 seconds (about 130–150 words).
Format: 8 scenes. For each scene give:
1) narration: the line to be spoken
2) picture: the image to show with that line (Indian context, rupee notes)

Rules:
- The first line is under 12 words: a number, a surprising fact or a question.
- Do the math step by step with round numbers (e.g. ₹10 × 200 cups = ₹2,000).
- Say clearly, once, near the start, that the figures are illustrative estimates.
- Count the owner's own labour and the slow days, not just the good days.
- Reveal something new every 2–3 scenes so people keep watching.
- End with a question viewers can answer in the comments.
- No investment, loan or "get rich quick" advice.

When the script arrives, send this second prompt in the same chat. The AI will check its own work:

Now act as a strict editor and check this script:
1) Score it from 1 to 10 for the hook, clarity, and whether the math is right.
2) List every line that is wrong, overconfident, or worth fact-checking.
3) Then give me the full improved version.

If it scores below 7, have it rewritten. And check the numbers yourself once: AI sometimes gets the math wrong while sounding completely sure.

For a long video (10–13 minutes)

In Prompt 1, change the length and format to: "45–60 scenes, about 13 minutes. A new chapter roughly every 50 seconds: price per item, cost of supplies, daily fixed costs, a day when everything sells, a slow day, break-even, the owner's labour, changing prices, cash flow, keeping records, the final lesson."

Option A: nothing to install

Clipchamp (Microsoft's free video editor, runs in the browser) has text-to-speech. Paste your script, pick a voice in your language, and the audio drops straight into your video. You'll do the editing in the same place in lesson 5.

Option B: on a laptop, ready for automation

Our channel uses edge-tts, a free Python tool that creates audio with Microsoft's natural-sounding voices. Save your script as script.txt and run:

pip install edge-tts
edge-tts --voice hi-IN-SwaraNeural --rate=+5% -f script.txt --write-media voice.mp3 --write-subtitles voice.srt

• hi-IN-SwaraNeural is a female Hindi voice and hi-IN-MadhurNeural a male one. Run edge-tts --list-voices to see voices in other languages.
• voice.srt holds the timing of every word. That's what the captions are built from.
• This isn't an official paid Microsoft service, so it can occasionally stop working or slow down. Keep option A as a backup.

Every scene needs a picture. Pixabay has free photos, illustrations and video clips you can use on YouTube. Read its license once before you start: images with brand logos or recognisable people need extra care.

Choosing the right picture

• Show exactly what is being said at that moment. "200 cups of tea" means cups of tea, not a sunset.
• Keep the local context. In one of our test videos, US dollar bills showed up while the voice talked about rupees. Viewers notice instantly, so check every picture.
• In a Short, change the picture every 5–7 seconds. It keeps the video moving.

Math cards: the most useful trick

While the numbers are being explained, show a simple text card instead of a photo, like this:

Daily sales
₹10 × 200 cups = ₹2,000
Milk, sugar, gas = – ₹1,100
Left over = ₹900

These take two minutes to make with the text tool in Clipchamp or Canva. Viewers follow the math, and your video stops looking like "just stock footage".

Clipchamp's free plan exports up to 1080p with no watermark and includes free AI subtitles, so it's all you need to start.

1. Pick the size: 9:16 (1080×1920) for a Short, 16:9 (1920×1080) for a long video.
2. Add the voice first. The whole video follows the voice.
3. Place each line's picture or math card under it.
4. Turn on captions (auto subtitles). Many people watch with the sound off.
5. Add a short headline at the top, like "₹2,000 a day?"
6. Music is optional: take a free track from the Audio Library in YouTube Studio and keep it low (~20%) so it doesn't drown the voice.
7. Export in 1080p.

A Short must be under 3 minutes. We keep ours around 50 seconds.

• Title: put the words people search for first. For example: "Tea stall business: the full math of one day's earnings".
• Thumbnail (long videos): 1280×720, one clear picture and 3–4 big words. Custom thumbnails need your channel verified by phone (youtube.com/verify).
• Description: sum up the video in the first 2 lines. For long videos add chapters (00:00 Intro, 00:48 Costs…), picture credits, and a line saying an AI voice was used.

Understand the "inauthentic content" rule

Since 15 July 2025, YouTube can remove "mass-produced" and repetitive videos from monetization. Using AI isn't banned. The problem is when every video looks like a copy of the same template and nothing in it shows your own contribution.

• Give every video something of your own: your own math, your own angle, your own takeaway.
• Rotate styles: a cost breakdown one day, myth vs fact the next, a comparison after that.
• Never re-upload other people's videos with small edits.
• Never buy fake views, likes or "sub4sub". YouTube can shut the channel down.

You can run a channel doing lessons 1–7 by hand. Our channel, though, runs itself every day, also for ₹0. This level is more technical (you'll need basic Python and GitHub). Here's how the whole system fits together:

1. Schedule: GitHub Actions starts the job at set times every day (twice a day for us).
2. Research: the YouTube Data API checks trending videos in the niche, search suggestions and the views on our own past videos.
3. Script: the Gemini API writes it, then an "editor" step scores it. Anything under 7 gets rewritten.
4. Voice: edge-tts creates the voice and the timing of every word.
5. Pictures: the Pixabay API returns several options per scene, and Gemini looks at them and picks the one that really matches the line.
6. Video: FFmpeg combines pictures, voice, captions and math cards into the final video.
7. Upload: the YouTube Data API uploads it, adds the AI disclosure, puts it in a playlist and posts the first comment.

Know this before you start

• API audit: videos uploaded through the API from a new Google Cloud project stay private until the project passes YouTube's audit. The audit form is free, but approval takes time.
• Limits: the free tiers have daily limits, and YouTube also limits uploads on new channels. 1–3 videos a day is the right range.
• Keep an eye on it: open your channel once a week. If you spot a video with a wrong fact, take it down.

To earn from ads, your channel has to join the YouTube Partner Program (YPP). The current rules:

There's also a smaller tier (500 subscribers, 3 uploads in 90 days, and 3,000 watch hours or 3 million Shorts views) that unlocks fan funding such as memberships, but not ad revenue. It isn't available in every country, so check your status in the Earn tab of YouTube Studio.

• Long videos matter: that's where watch hours come from. Shorts bring people in; long videos keep them. Link every Short to one of your long videos using "related video".
• Other ways to earn: affiliate links, your own service or product, and sponsorships later on.
• Be patient: most new channels take months. The ones that pull ahead are the ones that keep posting good videos for 3 months straight.
