Inkeep ships OpenKnowledge, a GPL'd local-first wiki built around AI agents

Inkeep has released OpenKnowledge, an open-source markdown editor and personal wiki pitched as an AI-first answer to Obsidian and Notion. The core idea is a local-first WYSIWYG editor — files stay as plain markdown on disk, but editing feels closer to a Notion or Google Docs page than a raw text buffer. It ships as a native macOS app and runs everywhere else (Linux, Windows, Intel Mac) as a local web app driven by a Node.js CLI.

The differentiator is its agent integration. Rather than bolting a chatbot onto notes, OpenKnowledge wires in Claude, Codex, and Cursor for collaborative editing and exposes the wiki through MCP, so any compatible agent can read and write the knowledge base. Built-in skills and agentic search target use cases like an LLM-queryable wiki, an agent ‘second brain,’ and spec-driven development. Team sharing and auto-sync are handled by git and GitHub underneath, but presented without requiring users to touch version control directly.

The project is licensed under GPL-3.0-or-later and accepts public pull requests, though its contribution model is worth noting: public PRs are automatically mirrored into Inkeep’s internal monorepo for review and merge. That open-source-with-a-private-core arrangement reflects a growing pattern among vendors who want community contributions while keeping primary development in-house.
