Cortex Desk
Bringing AI into how people learn and do research.
A chatbot in a separate tab won’t help you master a hard subject. We build tools that weave AI into the work itself — the reading, revision and practice where real progress happens.
Our mission is to bring AI into education and research — built for the specific work in front of you, not a generic assistant in another tab. A UPSC aspirant, a law student, a scientist and a schoolteacher each deserve tools that understand their world and earn a place in their daily study.
cortexlearnupscis our first product — a complete prep platform for one of the hardest exams anywhere. It turns the UPSC syllabus into living courses, spaced-repetition decks, interactive maps and simulations, an answer-writing studio, and an AI mentor that knows exactly what’s on your screen. Everything is built around one idea: understanding should compound, and AI should make the abstract finally click.
We’re only getting started. The same approach reaches far beyond a single exam — other examinations, higher study, research, and the everyday tools people use to think. We’re a small team building carefully and in the open, from Kanyakumari at the southern tip of India.
What we believe
Access for everyone
What we teach with is free, in full, to anyone with an account. The AI on top of it is priced to stay within a student's reach, not to ration the syllabus.
Built for your subject
Generic tools treat every subject the same. Ours are built around the UPSC syllabus, so the help you get fits the exam in front of you.
Depth over shortcuts
AI should build real understanding that compounds, not hand you an answer you forget by morning. Every tool we make is judged by what you retain.
How we charge
Only AI costs money. Everything you learn from is free to any signed-in account — every course, every test, every deck, no subscription and nothing held back. What we charge for is the work that runs a live model on your request, and that comes with an allowance before you pay anything.
