GRM Visual Designer (GPT)

Bring geometry to life — with fixed ratios and visual precision.

The GRM Visual Designer is a specialized AI assistant powered by the Geometric Ratio Model (GRM). It generates, analyzes, and optimizes images using fixed proportions. No π, no guesswork — just pure, measurable logic.

This GPT is built for:

  • AI artists and designers seeking visual harmony
  • Educators explaining geometric concepts in a clear and visual way
  • CAD developers implementing consistent shape ratios
  • AI engineers optimizing prompt efficiency and visual accuracy

Using standardized ratios like the SPU (0.7854 for a circle’s perimeter in a square) and SVU (0.5236 for a sphere’s volume in a cube), this assistant brings rational, repeatable, and aesthetically powerful image generation to life.


What can you do with it?

  • Generate DALL·E prompts with ratio-based visual logic
  • Compare “without GRM” vs “with GRM” visual series
  • Create visual explanations of geometric proportions
  • Design digital architecture using perfect form ratios
  • Save time and computing power with fewer prompt iterations

Backed by science

The GRM Visual Designer is based on the original Geometric Ratio Model developed by M.C.M. van Kroonenburgh, MSc, and follows the principles outlined in the official GRM whitepapers. All image prompts adhere to the core concept of form in relation to its frame.
