What's the story behind your product?

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.

DocFryer's answer:

Like many freelancers, contractors, and small business owners, I was constantly frustrated by simple document tools. You just want to generate a clean invoice or receipt, but you're met with: - Mandatory account registration and email verification - Hidden paywalls right when you click "Download" - Annoying watermarks slapped across your document - Having to upload sensitive client and pricing data to third-party servers

I wanted a fast, privacy-respecting, and beautifully designed suite of business documents that just works — right inside the browser.
