Hister is a private search engine that indexes the full contents of web pages and local files, allowing users to search for information from a web interface, terminal, or AI assistant. It is designed to be privacy-focused, with no telemetry or mandatory cloud service, and can be run locally or on infrastructure controlled by the user. Hister supports full-text and semantic search, and can import browser history, index local directories, and import files. The project is open-source and available on GitHub.
