Useful for understanding unfamiliar codebases and onboarding
From 3 comments
That's a game changer for a new Open source contributor's onboarding. Put in postgres or redis codebase, get a good understanding and get going to contribute.
wg0 on HNReally nice work and thank you for sharing. These are great demonstrations of the value of LLMs which help to go against the negative view on the impacts to junior engineers.…
zarkenfrood on HNThis is really cool and very practical. definitely will try it out for some projects soon. Can see some finetuning after generation being required, but assuming you know your own…

Impressive output quality
From 2 comments
I built browser use. Dayum, the results for our lib are really impressive, you didn’t touch outputs at all? One problem we have is maintaining the docs with current codebase…
gregpr07 on HNI had not used gemini before, so spent a fair bit of time yak shaving to get access to the right APIs and set up my Google project. (I have an OpenAPI key but it wasn't clear how…

Objections
Output tone is overly simplistic or overexcited
From 3 comments
This is actually really cool. I just tried it out using an AI studio API key and was pretty impressed. One issue I noticed was that the output was a little too much "for…
bilalq on HNThe overview diagrams it creates are pretty interesting, but the tone/style of the AI-generated text is insufferable to me - e.g.…
Retr0id on HNIs there a way to limit the number of exclamation marks in the output? It seems a trifle... overexcited at times.

Generated docs don't replace human documentation
From 1 comment
This is nice and fun for getting some fast indications on an unknown codebase, but, as others said here and elsewhere, it doesn't replace human-made documentation.…

Possible factual errors in generated code examples
From 1 comment
This is neat, but I did find an error in the output pretty quickly. (Disregard the mangled indentation) ``` # Use the Session as a context manager with requests.Session() as s:…

I love it! I effectively achieve similar results by asking Cursor lots of questions! Like at least one other person in the comments mentioned, I would like a slightly different…

Support for larger codebases beyond context limits
From 2 comments
I would find this more interesting if it made tutorials out if the Linux, LLVM, OpenZFS and FreeBSD codebases.
ryao on HNThis is super cool! I attempted to use this on a project and kept running into "This model's maximum context length is 200000 tokens. However, your messages resulted in 459974…

Questions
How much does it cost to run
From 1 comment
Did you measure how much it cost to run it against your examples? Trying to gauge how much it would cost to run this against my repos.

Can it use private repositories
From 1 comment
Is there an easy way to have this visit a private repository? I've got a new codebase to learn and it's behind credentials.

manofmanysmiles on HNWoah, this is really neat. My first step for many new libraries is to clone the repo, launch Claude code, and ask it to write good documentation for me. This would save a lot of…

Mutable AI

A company (mutable ai) was acquired by Google last year for essentially doing this but outputting a wiki instead of a tutorial.
