Ask HN: Any programming language or framework with LLM AI helper in website yet?

It seems obvious and inevitable that programming languages and programming frameworks/libraries will have dedicated LLM AI assistant specially trained on the language or framework topic accessible on the language or framework's website. Anyone know of a language or framework who has already put one up?

Imagine being able to ask the golang gopher or the rust crab "how do I build a REST app?" and being given a response with links to specific pages in the documentation. Imagine being able to do the same with (insert latest JS framework here) JS framework to ask how to create a web form with links in documentation. It would be interesting if language LLM ai assistants even knew of popular frameworks, libraries, or books to read.

It seems obvious because I suspect it would enhance the on-boarding experience of new programmers and eases the documentation search burden and thus would provide a competitive edge over other languages or frameworks.

Using documentation search functionality is already something all languages and frameworks offer but its much more limited than experience of using LLM AI assistants. A keyword search is a different experience than being able to explain some context.
