YouTube AI Chapters & Timestamp Generator 是什麼
Free AI chapter & timestamp generator for YouTube — no API key, no signup. Works on long podcasts too. Copy in one click. Add chapters to your YouTube videos in one click — no API key, no sign-up, free.
Chapters (the timestamps in a video's description and progress bar) help viewers navigate and boost your SEO — but writing them by hand is tedious, and most tools make you paste in your own paid OpenAI key. This one doesn't. Open your video, click the icon, and get a clean, ready-to-paste chapter list built from the video's captions.

WHAT IT DOES
- Generates chapters with timestamps from any YouTube video that has captions
- AI-written titles — clear, descriptive section names, free, no API key required
- NEW — long videos supported: podcasts, lectures and streams get chapters across the WHOLE video, not just the start
- One-click copy of the whole block, formatted for your description (first chapter at 0:00, as YouTube requires)
- Choose how many chapters: fewer/longer or more/shorter
- Pick the caption language track
- Works with manual and auto-generated captions
WHY IT'S DIFFERENT
展開其餘商店介紹▾
- Free, and you never enter an API key.
- Follows YouTube's chapter rules automatically: first chapter at 0:00, at least 3 chapters, each at least 10 seconds.
- If the AI engine is busy or offline, it falls back so you still get chapters.
GREAT FOR
- Creators who want navigable, SEO-friendly chapters without the busywork
- Long-form video, tutorials, podcasts, interviews, lectures, streams
- Anyone tired of tools that demand a paid API key
Whether you call it a YouTube chapter generator, timestamp generator, chapter marker maker, or a video table of contents — this adds chapters to your description in one click, free, with no API key.
HOW TO USE 1. Open a YouTube video that has captions. 2. Click the extension icon. 3. Press “Generate chapters”. 4. Click “Copy chapters” and paste the block into your video's description. If a video has no captions, you'll get a clear message — nothing breaks.
PRIVACY
- We never collect your account data, watch history, or identity.
- Only the video's PUBLIC captions are used.
- For AI titles, that public transcript is sent to our Lab Tools service (on Cloudflare) to write the titles, then discarded — we don't store or sell it. Prefer fully local? Switch to the on-device or Basic title engine and nothing leaves your browser.
- Minimal permissions: the extension only acts when you click it. No host permissions.
