Chiron is trying to make math feedback happen while the student is still writing.

## What it does

Chiron describes itself as “Grammarly for Math”: an iPad app that understands handwritten mathematics and gives feedback as the student works. The [YC profile](https://www.ycombinator.com/companies/chiron) says the product uses symbolic logic rather than relying only on a language model to assess the student’s reasoning.

The buyer fit is specific: students, parents, tutors, and schools that want feedback on working, not just an answer at the end.

| Fact | What the public source says |
| --- | --- |
| Buyer | Math learners, tutors, teachers, and education teams |
| Product | iPad whiteboard, handwriting understanding, symbolic checking, live feedback |
| Technical claim | The company says it converts strokes to LaTeX and evaluates work against a problem’s ground truth |
| Founder context | The Booth brothers are Oxford math graduates with a decade of tutoring between them |
