What's the story behind your product?

Fast3D.io's answer

After years of working on AI-powered tools, I was frustrated by how slow and complex 3D generation still felt in 2025. I wanted to build something that stripped it all down to the essentials: just type, click, and get your model. Fast3D is the result of that idea—a tool that feels magical because it works instantly.

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?

Fast3D.io's answer

As of now, Fast3D is in public beta and used by:

3D design students in major universities
