How To Add Chapters To YouTube Videos With AI - Using Just One Prompt

What the video explains

• Use an AI model to generate accurate, time-stamped YouTube chapters automatically from your video transcript so you don’t have to create them manually.
• Benefits:
  • Improves viewer navigation.
  • Boosts YouTube/Google Search visibility by surfacing key moments.
  • Free to implement with readily available tools.

Tools mentioned

• YouTube Analytics / share link (to get the video URL)
• tactic.tools — YouTube transcript extractor (provides transcript with timestamps)
• Claude (free tier) — used to run the chapter-generation prompt (alternatively ChatGPT or other LLMs)
• The creator’s ready-to-use prompt (provided in the video description)

Step-by-step guide

1. Open the video in YouTube (published or during upload) and copy the share link.
2. Use tactic.tools → YouTube transcript: paste the URL and get/copy the transcript with timestamps (or download it).
3. Paste the transcript into your chosen AI (Claude, ChatGPT, or another LLM).
4. Add the video duration alongside the transcript to ensure timestamps line up.
5. Use the provided “YouTube chapter generator” prompt that:
   • Assigns the AI the role of a YouTube chapter generator.
   • Supplies the transcript, topic, and link.
   • Instructs the AI to generate accurate, well-placed chapters with timestamps.
   • Emphasizes close attention to content and no repetition.
6. Run the prompt; review the generated chapters and paste them into your video’s chapter field in YouTube.

Prompt features and tips

• Role assignment (tell the model it’s a YouTube chapter generator) helps guide output.
• Include the transcript plus an explicit duration to ensure timestamps match the video.
• Ask the model to avoid repetition and focus on the content discussed for optimized chapter titles and placement.
• Works for both older videos (to optimize discoverability) and new uploads while editing.

Tip: Always review the AI-generated chapters for accuracy before publishing; small timestamp adjustments may be necessary.
