OpenWiki
The self-maintaining wiki. Built for agents, explored by humans.
About OpenWiki
OpenWiki is a CLI from LangChain that writes and maintains a wiki for a codebase. A documentation agent reads your sources, synthesises a linked Markdown wiki that lives in your repository and belongs to you, and updates it as the code changes. It is built to be read two ways: by coding agents, which use it as memory instead of re-deriving how a system works on every session, and by humans, through an interactive visualiser that turns the wiki into an explorable node graph.
Install openwiki from npm and run it against a repository in code mode, or against your own notes and sources in personal mode. The agent plans the wiki, then works page by page through a durable ordered queue: it submits a plan, generates each page with a focused worker, persists the Claims and source checkpoints for that page, and finishes. Because the queue is durable and checkpointed, a run that dies partway through does not start over, and in ephemeral CI it can open a pull request with partial progress rather than losing the work.
- •Grounded Claims - Material facts are tracked back to versioned source evidence, so when the evidence changes OpenWiki can surface exactly which statements are now suspect instead of quietly leaving them wrong
- •Two Modes - A
codewiki for a repository, or apersonalwiki built from your own knowledge and sources - •Thirteen Model Providers - OpenAI, Anthropic, Bedrock, Gemini and any OpenAI-compatible gateway, so the documentation agent is not tied to one vendor
- •Coding Agent Integrations - Runs inside Codex, Claude Code, OpenCode or Cursor using the host agent's authenticated model and native repository tools, while OpenWiki manages the documentation lifecycle
- •Nine Built-In Connectors - Custom MCP, Notion, Slack, Gmail, X, Web Search, Hacker News, LangSmith and local git repositories as sources
Teams whose codebase is large enough that onboarding is expensive and whose documentation has already fallen behind, and anyone running coding agents against a big repository who is tired of the agent rediscovering the same architecture every session - the wiki is explicitly designed as agent memory.
