What is Hister? Core Features of a Personal Local Search Engine

The core of Hister lies in automatically saving visited web pages to local storage and building a searchable index. Traditional browser history is temporary and lacks full-text search or content preservation. Hister solves this by enabling privacy-preserving rediscovery of past browsing.

It supports importing browsing history from Chrome and Firefox, allowing bulk ingestion of existing data. After import, page content is parsed and text is extracted. The periodic auto-fetch mechanism keeps bookmarked or frequently visited sites current.

Self-hosting ensures all data stays on your own machine or server. No dependency on cloud services means no risk of history being sent externally. Requirements include a machine with Docker or Python, with storage scaling to tens of GB depending on page count.

Installation and Initial Setup Steps

Supported OSes are macOS, Linux, and Windows. Prerequisites include Python 3.10+ and Docker. Clone the official repository and run pip install -e . for setup.

Initialize the database with the hister init command. SQLite is used by default, creating tables for indexing. No browser extension is needed; specify the path to your history file for import.

Launch the basic search UI with hister serve. A web interface opens on localhost, supporting keyword search and filters. Test with sample data on first run.

Periodic Updates and Index Management

Crawl intervals can be set from hourly to daily in the config file. Differential updates fetch only changed pages and deduplicate, improving storage efficiency.

Storage estimates assume ~50KB of text per page. 10,000 pages require ~500MB; 100,000 pages need ~5GB. Images and PDFs are optional; text is the default focus.

For troubleshooting, check logs with hister logs. Recovery commands allow index rebuilding. Regular tar backups are recommended.

Turning Hister into an MCP Server for AI Integration

Enable MCP protocol support by adding mcp_enabled: true to the config. This allows Claude and other AI agents to call Hister’s search capabilities.

Register Hister as a tool in Claude Code for connection examples. Integration with local file search enables cross-searching browser history and PC documents.

Security notes include restricting access via allowlists for IP addresses. Avoid opening ports externally; use VPN or authentication when needed.

Real-World Usage and Performance Comparison

Daily use cases include instantly finding a product page viewed a week ago via keyword. Compared to competitors, Hister excels in privacy and customizability.

Tool	Privacy	Search Precision	Setup Difficulty	AI Integration
Hister	Local-only	Full-text	Medium	MCP support
LocalSearch	Local	Keyword	Low	None
Meilisearch	Self-managed	Fast	High	Limited

Response time is under 0.1 seconds on local SSD, with over 90% precision from page content extraction. Workflow efficiency improves after adoption.
