Postlog

Postlog connects to a GitHub repository, private or public, and generates API documentation from the code using large language models.

It is an AI API documentation tool for developers who would rather not write endpoint docs by hand, and the short description says it supports multiple frameworks.

Output is organized into collections.

The Basic plan costs $0 and covers GitHub integration and up to 50 collections.

Pro is $10 and uses more advanced LLM models for more precise documents, adds the ability to edit collections, and raises the limit to 150.

Enterprise is priced through sales.

It adds role based access, unlimited collections, a feature for talking to your codebase, and the option to import generated collections straight into Postlog's own API Client, which only Enterprise users get access to.

The free tier is generous enough to try on a real project.

If accuracy matters more to you than cost, Pro is the plan to look at.
