I use AI at work. We have a huge codebase in Golang.

1000s of files.

I had tried cursor, claude code, gemini cli, openai codex and all sorts of vscode based idea (like windsurf, antigravity etc). All of them get overwhelmed when there is something to implement or change in the codebase primarily due to the amount of code.

But I like aider. I had better capabilities and is controllable, you can try. And if you use it with latest claude sonnet or gemini 2.5 pro it will be most accurate. Adding files is a manual process but it has nearly 100% code accuracy.

And it will never change anything without your knowledge.

You can try it.
