Semantic search for your browser history — fully local, privacy-first.

Histiq turns your browsing history into a searchable memory. Index every page and PDF you read — automatically, locally, privately — then find anything later by describing it, not by remembering exact keywords. 🔍 EXACT MATCH — OR SEARCH BY MEANING Remember the exact words? You get an instant match. Don't? Histiq searches by meaning instead — describe a page by a concept, a phrase, or a vague memory, and it surfaces the right one, even when none of your words appear on the page. Powered by a small in-browser embedding model (Xenova/MiniLM) that runs entirely on your device. 📖 READS THE WHOLE PAGE Histiq indexes the full text of a page — including collapsed FAQs, tabs, accordions, and "read more" sections that stay hidden until you click. Long articles and PDFs are split into chunks, so you can find something even if it was buried in the middle. 📄 PDFs INCLUDED When you open a PDF in your browser, Histiq automatically detects it, extracts the text layer, and indexes it — just like a regular web page. Search research papers, contracts, documentation, and any text-based PDF by meaning, not filename. 🔒 100% PRIVATE — TRULY LOCAL • Everything stored in your browser's local IndexedDB • Embeddings generated on your device — never sent anywhere • Zero network requests for your indexing or search • No account, no signup, no cloud sync • You can verify it: open DevTools → Network.
