This 100% Free AI Hack Creates Viral Short Videos on TikTok & Instagram

Overall purpose

The video explains a “100% free AI hack” to quickly create viral-style talking-avatar short videos (about 25–30 seconds) for TikTok and Instagram Reels, using free AI tools and a templated prompt/document.

Key concept: the 3 required ingredients

To recreate the style of viral shorts, the creator says you need:

1. An avatar (a character representing you/content)
2. A strong, engaging script that keeps viewers watching
3. AI tools to make the avatar talk and appear “alive”

A document (prompt sheet) is provided in the description and contains the prompts for each step.

Step-by-step tutorial / workflow (tools + actions)

1) Generate avatar image prompts (ChatGPT)

• Open ChatGPT
• Copy the first avatar prompt from the provided document
• Paste into ChatGPT and click Generate
• ChatGPT returns ~4 avatar image prompt options
• Use these prompts to create the actual avatar images

2) Create avatar images (Flow AI)

• Open Flow AI and create a new project
• Set:
  • Mode: image
  • Aspect ratio: 9:16 (vertical shorts)
  • Model: Nano Banana 2
• Paste the ChatGPT avatar prompt into Flow AI and generate images
• If results aren’t good, try the other prompts one by one
• Download the best avatar image to use as the base

3) Create style variations of the same avatar (ChatGPT + Flow AI)

• Copy the second prompt from the document into ChatGPT to generate multiple variations (different outfits/backgrounds) while preserving character identity
• In Flow AI:
  • select the chosen base avatar image
  • click “add to prompt” to use it as a reference
  • paste each variation prompt and generate new images
• Goal: consistent character identity with unique scenes/outfits

Script generation (ChatGPT)

• Copy the script prompt from the document
• Paste into ChatGPT and generate multiple short script options
• Choose the one that matches the intended message and style
• Scripts are designed for short-form retention and clear structure

Turn the avatar into a talking video (AI avatar voice + credits)

• Create an account on the “website” that provides the avatar/video generation
• Receive ~10 free credits (enough for ~2–3 videos)
• In the interface:
  • choose AI avatar
  • upload the avatar image
  • paste the chosen script into the script box
  • select an AI voice (voice picker pop-up)
  • click generate
• Credits usage: ~4 credits per video
• Rendering may take a few minutes

Edit and finalize (CapCut)

• Open CapCut
• Import the generated video
• Add it to the timeline for editing
• Handle watermark:
  • zoom in to remove the watermark from the frame
• Add captions:
  • use the captions feature
  • choose a caption style
  • subtitles are generated automatically and appear clean/professional

Publishing guidance

• Export the finished video
• Post on TikTok, Instagram Reels, and YouTube Shorts
• The creator claims results improve with practice and iteration

Example content shown in the subtitles

The video includes a sample script about bloating/gut health, with a call-to-action like:

• “Comment yes if you’re fixing your gut.”

(Serves as an example of how the persuasive talking-avatar format would look.)
