OpenWiki

The self-maintaining wiki. Built for agents, explored by humans.

Overview

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.

Generated documentation has one well-known failure mode, and it is not that the first draft is bad. It is that the draft is decent, the code moves, and six weeks later the docs confidently describe a system that no longer exists - which is worse than having no docs, because people believe them. OpenWiki's answer is Grounded Claims: material facts in a code wiki carry versioned evidence pointing at the source they came from, so when that evidence changes or disappears the tool knows precisely which propositions need to be confirmed, rewritten or retired. Whether that holds up in practice is the thing to evaluate before you trust it, and it is the reason to read the first generated wiki carefully rather than merging it. The project is young and moving: it is at an early 0.x version, and the repository generation flow was recently rebuilt into a resumable page-job pipeline, so expect the shape of the output to keep changing for a while yet.
