I know of a corporate who has embraced Claude for doing documentation of their codebase to better use Claude to do coding on the codebase.

So Claude can understand the codebase, it needs to document it. Makes sense and is also great for humans because now there is uptodate docu on the codebase.

I don’t know how much it cost but the codebase, I’m told, is around 2 to 3 million lines of code.
