Description

Pin Point fills a native gap in ChatGPT, Claude and Gemini: it adds a 📌 button to every message plus a side minimap to find and jump to the key points of long conversations instantly. Bookmarks (conversation, message index, excerpt and URL) stay only in your browser. Smart message re-location even after a reload. 100% offline, zero telemetry.

Features

  • 📌 button injected on every ChatGPT, Claude and Gemini message
  • Side minimap listing pinned messages with one-click jump
  • Manager popup: pins grouped by conversation, with open-chat and remove actions
  • Text-based message re-location when the index shifts (after reload or new messages)
  • Cross-tab sync via storage.onChanged; visual highlight of the reached message
  • Pure, immutable pin model (add/remove/list/serialize) with 42 Vitest tests
  • 100% offline: no network, no telemetry, data only in storage.local

Privacy

100% local processing in your browser. Zero telemetry: no data is sent to external servers.
