OpenWiki: CLI that writes and maintains agent documentation for your codebase

OpenWiki is a CLI tool that uses AI agents to automatically generate and maintain documentation wikis for codebases, with features including support for 13 model providers, integration with popular coding agents (Codex, Claude Code, Cursor), and self-updating capabilities via GitHub Actions or similar CI systems. The tool includes "Grounded Claims" that track documentation back to source code evidence, an interactive visualizer for exploring the wiki as a node graph, and outputs in an open, portable knowledge format. It can be installed via npm and run locally or integrated directly into coding environments to keep documentation accurate as code changes.
