Wenlan
Transform notes, codebases, and AI chat histories into a verified, living personal knowledge base that updates as sources change.
Wenlan is an open-source, local-first knowledge base that turns notes, source code, and AI interactions into a dynamic, interconnected wiki. Acting as a shared source of truth for you and your AI tools via MCP and native plugins, Wenlan automatically synthesizes inputs into atomic memories and cited Markdown pages. It strictly validates references against original sources, highlights out-of-date documentation when underlying code or notes change, and maintains your privacy by storing data locally with granular editing permissions.
