DeepDocs's answer:
Hi, I’m Neel — solo developer, and the founder of DeepDocs. I built this tool to solve a problem I kept facing at work: keeping high-level docs in sync with a fast-changing codebase. What started as a personal fix is now something I’m sharing with other developers who want to automate the annoying chore of keeping docs updated.
