## The Hook

OpenKnowledge is a GPL local markdown IDE and LLM wiki — WYSIWYG notes with side-by-side Claude/Codex/OpenCode agents, MCP, skills, and agentic search.

## What's Good

GPL-3.0 (inkeep/open-knowledge). Desktop (macOS/Windows/Linux) plus web UI/CLI; private local-first path; MCP/skills/agentic search for LLM wikis and specs. Homepage openknowledge.ai with download. ★~4,373 / F289. Free path is the GPL app on your machine — no paywall required to edit local markdown.

## The Catch

License: GPL-3.0 — copyleft applies if you redistribute modifications; fine for personal/internal use, diligence for SaaS forks. Vs Obsidian-class note apps and generic MCP file tools: this catch is a WYSIWYG markdown IDE with harness-side agent editing + MCP, not a second brain plugin alone. Team sync rides git/GitHub — that is ops, not magic.

## Verdict

GPL local markdown IDE when agents should edit your LLM wiki beside you — not a hosted Notion clone; respect copyleft on redistribute.
