One knowledge base.
Every AI tool.

Stop re-explaining your project to Claude Code, Cursor, OpenCode every session. CruxHive gives all your AI tools one shared, human-curated, searchable knowledge base — local SQLite, MIT, zero cloud.

01 / How it works

One server. Many tools. Three tiers.

AI TOOLS Claude Code OpenCode Cursor Windsurf Gemini CLI + any MCP client CruxHive MCP server · SQLite BM25 + entity + recency KNOWLEDGE LAYERS Personal ~/.cruxhive/personal/ Project .llm/ (in repo) Org shared remote · synced read CONTEXT.md + call MCP tools search · propose · review · approve · index human approval gate indexed locally git-versioned

Every AI tool reads from the same SQLite-backed index. You approve what goes in. Nothing leaves your machine.

02 / Tool-agnostic

Every AI tool reads from the same place.

One canonical .llm/CONTEXT.md per project. CruxHive symlinks CLAUDE.md, AGENT.md, .cursor/rules/, .windsurfRules, and GEMINI.md at it. Switch tools mid-day — same context.

For tools without their own session hook (Cursor, Windsurf, Gemini), cruxhive direnv wires a per-project .envrc so every shell entry is logged correctly.

03 / Trust gate

AI proposes. Humans approve. Knowledge compounds.

The single rule: no AI tool writes to the knowledge base without you saying yes. /extract distills a session into candidates, /summarize into a structured research entry — all queued for one-keystroke review.

Solo? Run cruxhive solo once — your own proposals auto-approve. Stay in control without the bureaucracy of a team approval queue.

04 / Cross-project

One workspace. Every project searchable from every other.

Working in backend, wondering "how did I solve auth in mobile?" — cruxhive search --workspace "auth" hits every project's index and merges results.

Or open cruxhive ui --workspace for a live dashboard with the 5 KPIs that matter: hit rate, gaps, queue age, decay, sessions. Trend deltas with cruxhive digest --compare.
