Local-first personal Markdown knowledge base with semantic search, AI Q&A, MCP, desktop/web clients, and a self-hostable zero-data-at-rest relay.
A personal Markdown knowledge base that lives on your computer and stays within reach of your AI — locally or from anywhere.
- Files first. Your notes remain ordinary .md files in a folder you control. - Agent native. Claude Code, Codex, Claude, ChatGPT, and other MCP clients can search, read, create, update, and share notes. - Local by construction. The index, retrieval, and writes stay on your home computer; AI calls use the provider you configure. - Remote without an account. Pair with a one-time code; the relay stores relationships and token hashes, never your knowledge-base content at rest. - Two commands to your phone. Install the engine, run homekb pair, and finish setup in the Web UI.
HomeKB turns a folder of Markdown files into a semantic knowledge base without moving ownership into a cloud app.
Drop notes into ~/.homekb/notes/ — or point HomeKB at an existing Markdown folder — and the Rust engine incrementally builds a local sqlite-vec index. You can then search by meaning, ask questions with citations, edit notes, or let an AI agent work with the library through MCP.
The command-line engine is the product core. The desktop app and Web UI are renderers over the same RPC contract, while the relay is only a pipe between a remote client and the engine running at home.
- Compile Markdown into summaries, chunks, document types, suggested questions, and embeddings. - Retrieve with dual-pool KNN over document summaries and chunks, fused with RRF. - Switch to whole-category enumeration when a question asks for coverage rather than a top-K match. - Answer questions fr
