Project Chiron
Grammarly for Math
Free
Chiron is the whiteboard that gives you complete confidence in your math - showing instantly if each step is right as you write.
CORE FEATURES
• Real-time verification of each step
• Natural handwriting understanding
• Built on symbolic logic, not LLMs or chatbots
• Rigorous mathematical foundation
SUPPORTED MATHEMATICS
• Number: arithmetic, inequalities, approximations
• Algebra: variables, functions, equivalences
• Trigonometry: trig functions, small angle approximations
• Calculus: derivatives, integrals, ODEs, infinitesimals
• Logarithms: any base, natural log, log rules
TECHNICAL PRECISION
• Implicit symbolic calculation engine
• Every line is either defining something or making a statement to be checked
• Work with complex mathematical notation
• Define variable domains and constraints
• Handle mathematical relations and equivalences
KEY DIFFERENCES
We're here to make doing math easier and faster by verifying each step as you write. We don't rely on a chatbot's "vibes" to tell you if you're right or wrong—we use solid, structured reasoning.
We are constantly developing and iterating based on user feedback to expand these capabilities.
Chiron is best experienced with an Apple Pencil.
