What's the story behind your product?

PromptDC's answer

Hey, it's Panagiotis 👋 Since late 2021, I’ve been building apps using only AI models. Over time, I realized the real problem wasn’t how good the coding models were, but how you write and structure prompts.

In 2024, a lot of different tools started popping up, like Cursor, Lovable, Bolt, and others. Each one had its own way of understanding prompts.

That’s when I had the idea 💡 What if I could just write my prompt the way I naturally think, and let the AI turn it into clear, structured instructions that the platform understands?

That’s why I built PromptDC.

For people like me who write fast, make typos, or don’t always structure their prompts To stop wasting credits typing all the time "FOR F*CK SAKE FIX THIS" To get better results in one click, without leaving the site you're already working on "I built PromptDC because I was tired of repeating myself. One click should be enough to get the result you asked for."

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.

Who are some of the biggest customers of your product?

PromptDC's answer

-Lovable users -Cursor users -Base44 users -Cline users -Bolt.new users -Copilot users -Replit users
