Semantic Memory of Browsing history

✨ New Ask My Memory — end a search with a question mark (e.g. "how does HNSW indexing work?") and get a synthesized answer pulled from across your browsing history, with clickable sources. Fully on-device — no AI servers. Memory Map — a brand-new tab that plots your entire knowledge space as an interactive 2D map. Related pages cluster together by topic; hover to preview, click to open. Address-bar search — type mem then your query in the address bar to search your memory without opening the popup. Light / Dark / Auto theme — pick one in Settings; Auto follows your system. Backup & restore — export your full index to a file and import it back (great for moving between devices).

🔧 Improved Smarter search ranking that mixes meaning, keywords, titles, and recency — and hides weak, unrelated matches. Filter results by time (all / today / week / month) and navigate them with ↑/↓ + Enter. Cleaner results: search-engine pages, chat apps, and webmail are no longer indexed, and revisiting a page updates it instead of creating duplicates. A real last-7-days activity chart, per-page delete in History and results, and a "pause indexing" switch.

🔒 Privacy Removed all third-party favicon requests — everything now renders locally. Still 100% on-device by default.

Semantic Memory is a Chrome extension that makes browser history actually useful. Instead of relying on exact keywords, it indexes the pages you visit using local AI embeddings so you can search by meaning. If you vaguely remember reading "that article explaining transformers" or "the blog comparing PostgreSQL and MongoDB", it'll find it even if those exact words never appeared in the title.

Everything runs locally in your browser by default. Your browsing data never leaves your device unless you explicitly enable encrypted sync. Along with semantic search, the extension can summarize the current page, find similar pages you've visited before, organize your history into a timeline, and show simple analytics about your browsing habits.

Built with Manifest V3, React, TypeScript, IndexedDB, ONNX Runtime, and Transformers.js, with an optional FastAPI backend for encrypted cross-device sync.
