The story

From one chemistry page to all of this.

H

Hunter

Founder of OmniEx
S-RANK BUILDER

OmniEx started as ChemLab: a single chemistry page with a periodic table and a few lab tools. I wanted revision to feel less like homework and more like something you'd actually choose to open.

So I kept adding to it. Maths, then History, English, Computing and even Plumbing. Accounts and cloud saves, so your progress follows you. Tools for teachers. An AI study helper. And then the System, which turns all of it into a game you can level up in.

A lot of what's on OmniEx started as someone's idea, and it's still growing every week. If you've got an idea, I'd love to hear it.
