Visual Knowledge Library
Cortex uses AI to turn any concept into a beautiful illustrated card and helps you actually retain it with spaced repetition.
The Problem
Cortex changes this.
How It Works
Create cortexes for every area you're learning—BJJ, philosophy, French, economics. Your brain has regions. So should your knowledge.
Type a concept name. Cortex generates a rich explanation and a custom illustrated card in seconds. No copying from Wikipedia. No creating flashcards by hand.
A dominant position in ground grappling where you pin your opponent...
Spaced repetition surfaces concepts right before you'd forget them. Three learning modes keep it challenging — flashcards, multiple choice, and fill-in-the-blank.
Beautiful by Default
AI-generated illustrations make abstract ideas visual and memorable. No more walls of text.
Why Cortex
Who It's For
Learning BJJ, philosophy, French, and economics—all at the same time. You need a system that keeps up.
New job, new domain. You need to get fluent in unfamiliar territory fast and sound like you know what you're talking about.
You believe in spaced repetition but Anki makes you want to quit. You want something that respects your intelligence and your eyes.
