Does this exist: copilot but trained with the latest docs (Expo / RN etc.) & all your local codebase?

Currently I'm using Cody + copilot + chatgpt but wondering if there's anything better

I was using it today and it told me it was searching some docs to help answer a question. I can’t remember what library it was searching the docs of.

I've been meaning to try it. Does it have the latest knowledge of api docs?
