OpenWiki
Turn a codebase and your notes into a living Markdown wiki, written on your ChatGPT plan.
About OpenWiki
OpenWiki from LangChain turns your codebase and knowledge sources into a linked Markdown wiki that you own. Coding agents use it over MCP to understand a repository, you can read it or explore it as a graph, and repository facts are traced back to source so updates focus on what changed. Its openai-chatgpt provider uses your ChatGPT subscription instead of a metered API key, drawing on your Plus, Pro or Team plan's included Codex usage.
Can you use your ChatGPT plan in OpenWiki?
Yes. ChatGPT Plus, Pro or Team, via the ChatGPT login provider. OpenWiki's own page says: "The openai-chatgpt provider calls OpenAI's Codex backend using your ChatGPT subscription instead of a metered API key, drawing on your Plus/Pro/Team plan's included Codex usage."
