Ask HN: How to share entire codebase with ChatGPT

I recently started a new job and need to quickly understand a large codebase. I’m considering using ChatGPT to help with this, but I’m not sure how to share the entire codebase effectively.

Has anyone figured out a way to share a large codebase with ChatGPT for better context and understanding? Are there any tools or methods that work best for this?

Just make sure your employer is okay with you sharing the codebase with an external agent, so ask first, you don't want this to cost your job..
