TraceMind: Local AI & Semantic History Search

Find pages again by describing what you remember. TraceMind turns readable pages you visit into a private, searchable memory inside your browser. Describe a tutorial, article, product, recipe, error message, or idea in your own words. TraceMind searches captured text by meaning and exact terms. Core capture, indexing, storage, screenshots, search, and analytics run locally. You do not need a TraceMind account for core search. THE PROBLEM: "I KNOW I READ THAT SOMEWHERE" You remember what a useful guide explained, but not its title, website, or exact words. Chrome history helps when you know the title or URL, but less when you remember only the idea. TraceMind captures useful text and metadata as you browse, then helps you rediscover a page by topic, phrase, domain, or date. HOW TRACEMIND SEARCH WORKS TraceMind combines local search methods for vague memories and precise details: - Semantic search compares the meaning of your query with the meaning of captured page text. - Full-text search finds exact phrases, error codes, names, product terms, and URL fragments. - Hybrid ranking blends those results so the strongest matches rise together. Search "mobile data for my trip to Europe" to surface a captured eSIM comparison without repeating its title. Exact function names and error codes favor the keyword index. The semantic model runs inside the extension, using WebGPU when available and WebAssembly otherwise. Keyword results can appear while the model or vector cache warms up. Semantic results require embeddings for the page. THE SEARCHES YOU CAN FINALLY DO - "That tutorial about making blurry photos look sharper" - "The article comparing two ways to merge ranked lists" - "Mobile data for my trip to Europe" - "The recipe with miso and eggplant I saw last month" - "What was I reading last Tuesday?" - An exact error code, product SKU, function name, or quotation Describe the page the way you remember it. Then narrow by date, domain, tag, saved status, notes, or pins when useful. WHAT TRACEMIND CAN DO SEMANTIC AND KEYWORD HISTORY SEARCH Search captured page text by meaning and exact language. TraceMind uses intent-aware hybrid ranking and shows match context to help you understand why a result appeared. AUTOMATIC READABLE-PAGE CAPTURE TraceMind captures readable text and metadata from supported HTTP and HTTPS pages, including supported single-page-app navigation. It skips Incognito. Protected or restricted pages and pages with little readable content may have limited or no capture. POPUP AND FULL DASHBOARD Use the popup for quick search, recent pages, and fixed date filters. Open the dashboard for more filters, sorting, pagination, bulk management, saved pages, and the complete workspace. New installs receive short, skippable popup and full-view guides to capture, search, filters, and navigation. Updates do not retrigger the tour for existing users. SEARCH BY DATE, DOMAIN, AND ORGANIZATION Filter by date and domain on Free. Pro adds custom date ranges, hour filtering, tags, notes, and pinned pages. Sort results by relevance, recent activity, or visit count. SAVE PAGES ON FREE Save useful pages into a dedicated Saved view. Saved pages are protected from finite retention cleanup. Saving is local; it is not cloud synchronization. NOTES, TAGS, AND PINS ON PRO Add notes, organize with tags, accept suggested tags, and pin important pages. Suggested tags use page, domain, and topic signals and remain under your control. SCREENSHOTS AND VISUAL PREVIEWS TraceMind can store local screenshot previews for eligible active pages when capture succeeds. Free includes Low quality. Pro adds Medium, High, and Ultra HD choices up to a configured 1920 x 1080 target. Compression and capture limits can reduce the final image or dimensions. MULTILINGUAL SEMANTIC SEARCH TraceMind starts with a fast English model. For cross-language search, choose Multilingual MiniLM L12. It runs locally and rebuilds the semantic index in the background while keyword search remains available. Unicode-aware query handling supports non-Latin searches, including Japanese-only queries, after the rebuild completes. LOCAL BROWSING INSIGHTS See indexed pages, visit activity, peak browsing hour, top domains, daily patterns, hourly patterns, monthly activity, and local storage information. Free includes core activity and storage views. Pro adds custom date ranges and chart-driven filtering. CHAT WITH YOUR HISTORY ON PRO Ask questions about your history and receive streamed answers with citations back to selected sources. Choose OpenAI, Anthropic, or Google Gemini and bring your own API key. Chat is optional and off until enabled. Retrieval is local. A question sends selected matching excerpts, titles, URLs, and the active in-memory conversation directly to your configured provider. TraceMind does not proxy or retain those requests. Your key is stored locally, excluded from backups, and not protected by the optional content passphrase. Chat turns are not saved as TraceMind history. Provider processing follows that provider's terms and privacy practices. IMPORT YOUR EXISTING CHROME HISTORY Start with metadata from Chrome history instead of an empty list. TraceMind can import up to 10,000 Chrome-history records from the previous 365 days. Chrome imports do not include historical page text, screenshots, offline copies, or semantic embeddings. Imported records support title and URL search immediately. Revisit a page to capture its readable text and create its semantic index. KEEP CAPTURED HISTORY FOR AS LONG AS YOU CHOOSE New TraceMind captures default to keep forever, and TraceMind does not impose a product-level page-count cap. Browser and device storage remain the practical limit. You can choose a finite retention window instead. Saved pages are exempt from finite automatic cleanup. This captured-history retention is separate from Chrome-history import, which currently reaches back up to 365 days. BACK U…
