Ask HN: What's the best AI coding assistant tool?

I think with the reasoning models, LLMs can be more useful at coding than just smarter autocomplete and search. I have not tried any yet though.

What is the best process or tool to use AI to help me code in a specific somewhat large codebase?

Probably better to be model agnostic. The more integrated in my coding setup the better (I use VSCode, mostly Typescript, work in basic Saas stuff, nothing advanced, if it matters).
