WORKFLOW
Capture, format, validate, copy.
The extension stays intentionally small: no account, no backend, no AI dependency, and no cloud sync are required for the core workflow.
Format
Paste rough timestamps such as 1.20, 80 sec, 1m20, or 00:01:20 and normalize them automatically.
Validate
Check chapter count, 00:00 start, ordering, duplicates, titles, and minimum 10-second spacing.
Copy
Copy YouTube or Markdown output, or export clean TXT and CSV files.
GALLERY
Product visuals
These concept visuals introduce the product and its workflow. The Chrome Web Store listing will use final real-extension screenshots alongside the marketing artwork.
PRIVACY
Private by design.
Chapter timestamps and titles stay in chrome.storage.local on the device. The current release candidate has no account, analytics, advertising, AI service, cloud sync, or backend service.
