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.

GalleryPlanner's answer:

GalleryPlanner was created by Tim Straub, a data scientist, after a real home project: turning a growing family frame collection into a clean wall layout with exact spacing.

Existing options did not meet two core needs:

  • precision (exact nail placement and spacing),
  • privacy (no unnecessary cloud photo uploads).

So he built GalleryPlanner as a local-first, measurement-accurate planner for practical, confidence-first installs.

Who are some of the biggest customers of your product?

GalleryPlanner's answer:

  • DIY homeowners
  • families planning personal gallery walls
  • independent interior designers using client previews
