Hister is a private search engine for the pages you visit and the files you keep. It indexes their full contents so you can find information again from the web interface, terminal, or an AI assistant connected through MCP.
Try the demo · Download Hister · Read the quickstart · Documentation
Download the binary for your platform from the latest release, then rename it to hister (hister.exe on Windows).
On Linux or macOS, make it executable:
Start Hister on Linux or macOS:
On Windows, run .hister.exe listen in PowerShell.
Keep this terminal open while using Hister. The server must be running to index pages and search them.
Open http://127.0.0.1:4433 and install the browser extension for Firefox or Chrome.
Visit a web page with the extension enabled, then return to Hister and search for a phrase from that page to find your first indexed result.
No configuration is required for a local personal setup. See the complete quickstart to choose what Hister indexes.
To search existing content, import browser history, index local directories, or import files.
Alternative installation methods include Homebrew (brew install hister), Docker, and Nix. See the installation guide for instructions.
By default, Hister has no telemetry and no cloud sync. The browser extension sends indexed page content only to the Hister server you configure, apart from downloading page favicons. The server stores documents and search indexes on that server.
Optional semantic search sends document text to the embeddings endpoint you choose. Review the privacy overview and semantic search configuration before enabling remote integrations.
Unlike traditional search engines, Hister builds a personal search index from the web pages and files you choose to keep. Your content stays on your Hister server, making it useful for finding information you’ve already encountered without relying on a third-party search provider.
Requirements are Go 1.26, npm, and a C compiler for CGO dependencies.
To work on the web app with hot reload and automatic Go rebuilds:
This starts a Vite development server and the Go backend with automatic rebuilds through air.
