Photomath

Photomath belongs in the catalog because it still defines the quick-start experience for students who want help from the page in front of them, not from a blank prompt box. The product is built around scanning math problems and turning them into understandable steps, which keeps it useful even as more expansive AI tutors enter the market. In practice, that simplicity is the feature. Many students do not need a general chatbot for algebra homework. They need a fast way to capture the expression, see the method, and understand why the answer unfolds the way it does.

It also deserves inclusion because the public pricing is unusually straightforward. The official site currently lists Basic at $0, an annual paid option at $69.99, and a monthly option at $9.99. The paid tiers add richer help such as custom visual aids and extra 'how' and 'why' tips. That makes Photomath easy to compare: the free tier gets students into step-by-step explanations immediately, while the paid tier exists for families that want deeper instructional support rather than just answer checking.
