Video Chapter & Timestamp Generator
Paste or upload a timed transcript of your own video and get chapter timestamps and a ready-to-paste description block, with every timestamp taken from the transcript.
Economics
- Pricing example
- $9 for 30 videos (first 3 free)
- Daily math
- 2-3 packs a day x $9 = $18-27/day.
- Target if you hit the daily math
- Target: $550 - $800 / month if the daily math is hit
Audience and urgency
Audience: YouTubers, podcasters who publish video, educators and course creators publishing long videos.
Urgency: Chapters make long videos easier to navigate, but writing them means scrubbing through the video and noting times by hand. Creators who publish weekly skip it because it takes too long.
MVP scope
- ✓ Upload SRT/VTT or paste a timestamped transcript of your own video
- ✓ LLM picks topic boundaries by cue number; timestamps are copied from the cues, never generated
- ✓ Editable chapter list with a check against the platform's current chapter rules (e.g. first chapter at 0:00, minimum chapter length)
- ✓ Description block builder: summary, chapters, links and hashtags the user adds
- ✓ Credit packs via Stripe; copy-to-clipboard and .txt export
Omitted features
- - Do NOT download videos or fetch captions from other people's videos
- - Do NOT upload or edit videos on any platform automatically
- - Do NOT do speech-to-text in Day 1 (bring your own transcript)

One-shot master prompt
Build a "Chapter Generator" web app in React with Tailwind CSS and a serverless LLM endpoint.
Core requirements:
1. Input: upload .srt/.vtt or paste a transcript with timestamps; parse into cues (index, start time, text) in the browser.
2. Send cue indices and text (chunked if long) to the LLM with a JSON schema returning chapters as {startCueIndex, title}. Build timestamps only from the referenced cues' start times; reject indices that don't exist.
3. Editable chapter list (rename, merge, split at a cue, delete) with a rules check: first chapter at 0:00, at least 3 chapters, each chapter at least 10 seconds, ascending order. Show the rules as editable settings, since platform rules can change.
4. Description builder: summary paragraph (LLM draft the user edits), chapter block, user-added links and hashtags; copy button and .txt export.
5. 3 free videos, then Stripe Checkout ($9 for 30). Nothing is stored after the session.Comparable products
