James Booth & Max Booth for Chiron, a neurosymbolic AI app for mathematical reasoning + Super Tutoring
https://projectchiron.org/about-us
Chiron is building what the brothers and co-founders describe as “Grammarly for Math.” It is an iPad application designed to understand mathematical equations exactly as they are written by hand on a screen. Using symbolic logic and AI, the platform provides students with real-time feedback on every stroke (in under 300 milliseconds). While highly applicable to high school, it scales directly into university-level courses like Calculus I, correcting the common issue where generic AI struggles to spot specific procedural math mistakes.
James Booth & Max Booth are brothers and co-founders from the UK. Both are graduates of mathematics at Oxford University. Their vision stems from their academic expertise combined with extensive experience as personal tutors. This combined knowledge allowed them to build the app that seeks to “shift math practice from a static, frustrating process into an active, 1-on-1 feedback loop.”
The webpage describing Chiron, along with their brief bios, suggests that the brothers are heavily invested in active learning and promoting exploratory learning for students. Their app helps to move away from passive learning and foster the ethical AI usage within this space. The ‘super tutoring’ angle speaks to parents directly, identifying the real paint point of kids meeting with tutors weekly, but continuing to make the same mistakes. With Chiron, work is watched between session, reading student handwriting in real time and catching mistakes when they happen, to course correct on the spot. There is a human in the loop for this as well, as Chiron reports the findings to the ‘Super Tutors’ (the co-founders) can assist the student directly. In other words, this is a technology that requires a human element, and so scalability for the ‘Super Tutoring’ layer as a value prop will be something the co-founders will need to continue to think through moving forward. Overall, I think this project has great potential. The co-founders have taken the time to address teachers directly on their webpage and have addressed considerations around AI ethics, the future of learning and teaching, and what students might be able to do to expand their horizons in the field of mathematics.
I think James and Max represent strong role models for would-be entrepreneurs because Chiron is built around a very specific and meaningful learning problem: students often do not just need the final answer in math; they need feedback on their thinking process while they are working. Their “Grammarly for Math” idea is compelling because it targets the moment when mistakes actually happen, instead of only correcting work after the fact.
What makes them especially interesting as founder-leaders is the combination of subject expertise, tutoring experience, and technical vision. Since both founders have strong mathematics backgrounds and years of tutoring experience, their venture seems grounded in real learner needs rather than just the excitement around AI. I also appreciated your point about the human-in-the-loop element. Chiron is not presented as replacing teachers or tutors completely, but as creating more timely feedback and better visibility into student learning.
One question I would be interested in watching is scalability. The real-time AI feedback seems highly scalable, but the “Super Tutoring” layer may require careful design if the company grows. Still, this is also what makes the venture thoughtful: the founders seem aware that math learning is not only about automation, but also about guidance, confidence, and active practice.
