Hister turns the pages you visit and the files you keep into a private, full content search index that you control.
Free software on GitHubSelf hosted
Run it on your own machine or server
Privacy focused
No telemetry, no external requests
Preserve Knowledge.
Hister stores extracted document content with the search index and displays it as a readable preview alongside search results.
Search the content you chose to index
Look beyond bookmarks and filenames. Hister indexes the full content of the pages and files you choose, then keeps that searchable knowledge on a server you control.
Search the actual content
Look beyond titles and URLs to the words inside every indexed document.
Narrow with precision
Use fields, phrases, wildcards, negation, priorities, and your own aliases.
Read it in context
Open a clean stored preview beside the results without losing your search.
A private memory without the busywork
Save newly visited pages with the browser extension, watch local folders, import your history, or crawl a site.
Hister extracts the parts that matter and indexes their full text on the server you choose.
Search from the web, terminal, command line, or let an AI assistant retrieve it through MCP.
Browser extensions can index pages as they are visited. File watchers, history imports, and crawlers add other sources to the same index.
Preserve Knowledge.
The index, stored page content, and rules remain on the Hister server you configure. The server has no telemetry and does not require a cloud service.
Read the privacy modelNo telemetry
The server does not phone home or report what you search.
No mandatory cloud
A complete personal setup can run on one local machine.
Your chosen server
Clients send indexed content only to the Hister server you configure.
Auditable software
The source is public and licensed as free software under AGPLv3.
Optional semantic search sends text to the embeddings endpoint you configure. Browser extensions may retrieve page favicons. You choose whether and where these connections run.
