Sohil Rathi

I build tools that make complex ideas easier to understand.

I am a builder working at the intersection of mathematics, education, and AI. I have created math textbooks, educational games, and visual explanations reaching students around the world.

Now I am building Limerse to reimagine what the textbooks of the future should look like.

Limerse

limerse.com

The next generation of math textbooks.

Limerse creates complete online textbooks with immersive visual explanations and interactive examples. Using a custom animation engine and AI pipeline, it transforms a teacher's handwriting, voice, and teaching style into production-quality visual lessons that feel like learning from a real teacher.
