Supacodes watches a GitHub repository and regenerates its code documentation every time new commits land, aiming to solve the problem of documentation that's accurate on day one and wrong by week three. It supports TypeScript, JavaScript, Python, Java, PHP, Dart, C, and C++, covering most of what a typical polyglot team would need.
The pitch is narrow and specific: instead of a general-purpose AI writing assistant, it's a background process tied to a CI pipeline that keeps internal docs honest without anyone remembering to update them. That makes it closer to infrastructure than to a tool developers open and interact with directly.
It's free to use, which for a tool this specialized suggests it's either early stage and building usage, or monetizing through an enterprise tier not reflected in the public pricing.
