Funny coincidence – saw this very similar, perhaps more polished variant of the idea trending on twitter today: https://twitter.com/fronseneca/status/1752125155667824764?s=...
First, we pre-build a codebase-wide index for large repos that's readily available vs some kind of local VSCode plugin.
Secondly, we cover different languages. We started with deep support for C/C++ based on clang while they seem to be focused on TypeScript.
I'm curious why you'd say that theirs is more polished?
