What's the story behind your product?

ManyTools's answer

I kept running into the same problem - every time I needed a simple tool, I'd spend more time searching than actually doing the work. Ten tabs open, half the results were outdated listicles, and the other half were ads. So I started bookmarking the good ones. That bookmark folder turned into a spreadsheet, and the spreadsheet turned into ManyTools. Now it's a directory of 1,200+ tools across 72 categories, rated by people who actually use them.

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.
