Technical Overview
Photomath is a consumer-facing mobile application — there is no publicly documented developer API. Here is what is known about its technical architecture:
- OCR & Computer Vision: The app uses camera-based optical character recognition to capture and interpret both printed and handwritten mathematical expressions, including multi-line problems and word problems.
- Math Solving Engine: A proprietary backend engine parses the recognized expression and computes solutions across a broad curriculum scope (arithmetic, algebra, geometry, trigonometry, statistics, calculus). Multiple solution paths can be returned for a single problem.
- Smart Calculator Input: In addition to camera scanning, users can manually enter expressions via an in-app smart calculator, supporting complex notation.
- Platform: Available on iOS and Android as a native mobile app. No self-hosting or API integration options are publicly available.
- Subscription Model: Free tier provides basic step-by-step explanations; paid tiers unlock custom visual aids and enriched contextual annotations billed monthly ($9.99/mo) or annually ($69.99/yr).
