What Chiron does

Chiron is an iPad app that understands math as it’s written - like Grammarly for algebra. We’re both Oxford math grads, have tutored for a decade, and we’re creating the future of learning which will be entirely 1-on-1.

Grammarly for Math ✏️

What is your company going to make? Please describe your product and what it does or will do.

We're building an iPad app that understands math as it's handwritten and provides instant feedback, corrections, and tutoring help - effectively a Grammarly for algebra. It's designed to make 1-on-1 learning scalable and interactive, helping students write and solve math problems properly rather than just getting answers.

Where do you live now, and where would the company be based after YC?

We live in London, and the company will be based in London after YC.

Explain your decision regarding location.

We are based in London because that's where we live and where we've done our tutoring for a decade. Staying here means we can continue close contact with early users and understand the UK education market deeply.

Frequently Asked Questions

Is this the real Chiron YC application?

No. Y Combinator keeps submitted applications private. This is a reconstruction: the real YC form questions, answered from Chiron's public data (launch notes, founder backgrounds, product description). It shows how a company like Chiron would present itself to YC, not the text they submitted.
