History Signals – Browser History Insights

History Signals turns browser history into a private, long-lived record you can search, review, and understand. Chrome normally keeps only a limited window of history. History Signals imports the records Chrome still has, then saves new visits automatically in a local archive on your device. Keep what Chrome forgets • Save new browser visits automatically • Keep history forever by default • Search by page title, URL, or domain • Browse related visits as chronological paths • Export your archive as JSON or CSV See the patterns Review activity across 7, 30, 90 days, or your full archive. Explore frequently revisited sites, active hours, recurring pages, and browsing paths behind the numbers. Understand what keeps returning Insights help reconnect browsing fragments: subjects you repeatedly return to, lines of research that span different websites, and shifts in what you have been exploring. Every device can produce a limited deterministic local interpretation. On compatible Chrome devices, you can optionally enable Chrome's built-in Gemini Nano model for a richer, source-linked analysis. Gemini Nano is optional. Model preparation and analysis happen on the device. Page content is never supplied to the model. Private by design • Browsing records stay in local IndexedDB • No account, advertising, analytics, or developer-operated server • No collection of webpage content • No sale or sharing of browsing history • Source-linked insights you can check against your own records • Open-source implementation for auditable privacy boundaries Optional encrypted WebDAV copy Advanced users may configure an encrypted WebDAV copy. It is experimental and disabled by default. In-app restore and integrity verification are not yet available, so this feature should not be treated as complete disaster recovery.
