Claude Toolbox extension adds message-level bookmarks and full-text search
Claude Toolbox is a Chrome extension specifically for claude.ai that adds message-level bookmarks, full-text search across all your synced conversations, and one-click export as TXT or JSON. The project was built with heavy use of Claude Code — the developer used it to scaffold the IndexedDB sync layer, write the first pass of the message-bookmark schema, debug a race condition in the background sync, and draft i18n strings for 10 locales.
Features
- Message-level bookmarks: Bookmark any individual reply in a Claude conversation. Optionally add a label. Click the bookmark later and the page scrolls directly to that message with a brief highlight animation.
- Full-text search: Search across all synced conversations (not just the current one). Free tier includes this feature.
- Export: One-click export of conversations as TXT or JSON.
- Background sync: Bookmarks and history sync in the background (race condition debugged via Claude logs).
Pricing
The free tier includes full-text search, bookmarking across up to 2 conversations, and background sync. The paid tier (intended for unlimited conversations) is $5/month or a $49 one-time lifetime payment.
How Claude helped build it
The developer explicitly credits Claude Code for:
- Scaffolding the IndexedDB sync layer and migration logic
- Writing the first pass of the message-bookmark schema and scroll-to-highlight animation
- Debugging a background sync race condition by pasting worker logs into Claude
- Drafting i18n strings for all 10 locales by providing the EN file and requesting one locale at a time
