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.
Diffyn's answer:
I started working on Diffyn when I notice that prompting has become an essential part of work across many industries. While there are version control platofrms like github, they are not designed for just prompt management are can be overkill such applications, it is also not integrated natively with various LLMs and relevant tools for users to validate ideas and visualise results properly.
