Show HN: Open-Source Visual Wiki Your Coding Agent Writes for You (docs.davia.ai)

Davia is an open-source, npm-installable tool that lets your AI coding agent automatically generate interactive, visual documentation for large codebases—think diagrams, flow charts and editable whiteboards that live alongside your repo. After installing the davia CLI (requires Node.js and npm), you run davia init in a project and link the AI coding agent in your IDE (or skip linking and run davia init alone). The agent then analyzes the codebase and emits interactive documents using Davia’s paradigm; you open a local Davia workspace in your browser to view and edit diagrams and notes, and when ready you can push the workspace to Davia’s cloud for real-time team collaboration. For the AI/ML community this bridges automated code understanding and tangible, visual documentation: it speeds onboarding, code reviews and navigation of complex systems by turning agent insights into browsable artifacts. Key technical points: Davia is local-first (edits happen locally), distributed via npm, integrates with multiple coding agents, and provides a davia push flow that currently creates a new cloud workspace each time (editing/updating an existing cloud workspace isn’t supported yet). Implications include faster developer workflows and reproducible docs, but also the usual caveats—documentation quality depends on the underlying agent and teams should consider privacy and repo access policies when syncing to the cloud.
