Ask HN: Best AI Assistant for Large Codebases?

1 surrTurr 0 6/11/2025, 4:42:13 PM

I'm currently using GitHub Copilot, which works well for small projects / project that have little rules enforced. However, when using GH Copilot on a large codebase, with certain rules, architectural patterns etc, it's suggestions start degrading since they do not fit into the overall context anymore.

I was wondering, what's the best AI assistant, that also indexes the whole codebase and makes inline suggestions based on that information.

I saw GH Copilot has an indexing function (when used in VS Code), however it is limited to 2000 files.

I saw Codeium offers a remote indexing feature, which looks interesting, but I haven' t used it yet. Does anyone have experience with it?
