Project Chiron is an iPad app that understands math as it’s written, offering a unique, interactive approach to learning algebra and other math topics. Project Chiron enables students to freely write on a digital whiteboard, providing immediate, intelligent feedback on their handwritten math work—much like Grammarly does for writing, but for mathematics.
How Does Project Chiron Work?
Chiron’s core technology converts handwritten math (using stroke data) into LaTeX, parses it, and checks each step for correctness by comparing it to mathematical ground truth. This process enables real-time, step-by-step feedback without relying on large language models. The app combines:
- Freeform writing on a digital whiteboard, encouraging natural mathematical expression
- Calculator-level accuracy using symbolic logic
- Instant feedback on every pen stroke, helping learners improve as they work
What Makes Project Chiron Different?
Unlike many math learning platforms that depend on language models or rigid answer formats, Chiron’s approach is based on parsing the actual mathematical logic behind each step a student takes. This allows for:
- More flexible input: students can solve problems as they would on paper
- Deeper assessment: the app can analyze solution strategies, not just final answers
- Enhanced learning: real-time corrections and suggestions foster a more active learning experience
Who Is Project Chiron For?
While specific customer names are not listed, Project Chiron is designed for students and educators seeking an interactive, one-on-one math learning experience. Its features are particularly suited to:
- Students learning algebra and related subjects who benefit from stepwise feedback
- Tutors and teachers aiming to provide personalized, digital instruction
- Educational organizations exploring innovative math technology
How Was Project Chiron Started?
Project Chiron was founded by the Booth Brothers, James and Max, both Oxford mathematics graduates and experienced math tutors. Their backgrounds include over a decade of tutoring and careers in quantitative trading at Jane Street and Optiver. Their personal experiences with transformative math education inspired them to create a tool that makes learning math active and experimental for everyone. You can read more about their story on their About Us page.
Where Can You Find Project Chiron?
The app is available for download on the App Store. Project Chiron was also launched on Y Combinator's Launch YC platform in July 2025.
