Show HN: I built a CLI tool that uses AI to document an entire Python codebase
For years, I've dealt with the pain of undocumented Python projects. It makes onboarding new devs a nightmare and brings refactoring to a crawl. Existing tools can lint for missing docstrings, but they don't actually write them for you.
I wanted a tool that could just fix the problem. So, I built Docu-AI Pro.
It's a simple Python CLI tool that recursively scans a directory, finds every function without a docstring, and uses an AST-based analysis (a smart simulation of an AI for now) to generate a clear, helpful one. It correctly identifies parameters, return statements, and even infers the function's purpose from its name and structure.
It's idempotent, so you can run it safely on a project anytime. The goal is to get a codebase from 0% to 80% documented in about 5 minutes.
I've packaged it as a lifetime deal for $49. I'm hoping to build it into a more powerful tool with true LLM integration in the future, and early buyers will get all 1.x updates.
I'd love for you to check it out and hear your feedback.
