AI can search your code today. In cursor this is called “codebase indexing”. We have some million(s) lines of code, orders of magnitude smaller than Facebook, but definitely larger than the average startup. We search with AI tools, through Q&A, and for AI-driven code mods. Cursor also exposes LSP stuff to their AI system so it can look at that tool.

Sourcegraph Cody is another example of a code AI that can search.
