OpenDoc-AI: Local-first AI CLI for code docs & Mermaid.js diagrams

Hi Product Hunt! 👋

I'm George, creator of OpenDoc-AI.

We all know code documentation is essential, but manually writing and updating it is tedious. Cloud-based AI tools can help, but sending proprietary codebases to external servers is a major security risk for many developers and teams.

I built OpenDoc-AI to offer a local-first alternative. It scans your source code, writes structured Markdown docs, and generates visual Mermaid.js architecture diagrams—all running locally via Ollama.

How to get started:

1. Make sure Ollama is running (`ollama pull qwen2.5-coder`)

2. Install via pip: `pipx install opendoc-ai`

3. Run: `opendoc-ai scan --source ./src --output ./docs`
