Honestly, I didn't know before that you could just point a camera at a problem and get a ready-made solution. Turns out, by 2025, this is already common practice — neural networks have learned to recognize not only printed text but also handwritten formulas, graphs, everything in between. The smartphone has become a 24/7 assistant for homework.

I tested several popular services. Photomath is a classic for mathematics. Point your camera at an equation, and within a second, you see not just the answer but a full step-by-step solution breakdown. But the downside is that it only works with math, and doesn't solve physics or chemistry problems. Plus, a subscription is required for full access.

MathGPT is more interesting — here, you can solve problems from a photo across three subjects: math, physics, chemistry. Free, no registration needed. The interface is in English, which might confuse younger students.

Wolfram|Alpha is for serious calculations. It doesn't just give an answer but computes it itself, builds graphs, solves integrals. Covers hundreds of topics. But photo recognition is only available in the paid version.

There’s also Mathway and Symbolab — both allow solving math problems from a photo with step-by-step explanations. Symbolab is especially good for students: it displays formulas nicely, covers calculus, differential equations — everything.

BotHub is an aggregator that combines ChatGPT, Gemini, Claude, and other models. More versatile than specialized solvers. You can use different neural networks in one place, with a free plan available.

Gauth also covers many subjects: not just math but biology, economics, languages. Upload a photo — get a detailed solution with all explanations.

Newcomer — Nano Banana Pro from Google DeepMind. It’s not just a solver but an image generator with analytics. Can recognize handwritten notes, solve an example, and even reproduce the answer in the same handwriting. Plus, it formats solutions as infographics or diagrams.

In general, if you need to quickly solve a problem from a photo — there are options to choose from. For school math, Photomath, Mathway, Symbolab are suitable. For serious science, Wolfram|Alpha. If you need versatility — BotHub or Gauth. The main thing is to remember that these are assistants, not replacements for learning.
