Actually, I found a bunch of services online that solve problems just from a photo. Like, you point your camera at an equation and get the solution photo in a few seconds. Crazy stuff, honestly.

I tested a few. Photomath — the classic option, works with handwritten and printed text, shows step-by-step solutions. But only for math. Mathway is similar, but has a more user-friendly interface. Symbolab is really powerful — it even solves integrals and formats formulas nicely.

If you need more than just math — there's MathGPT, which also covers physics and chemistry. Free, by the way. Or Gauth — it covers biology, languages, economics. More versatile.

In general, the most flexible option is BotHub. It's like an aggregator of different neural networks (ChatGPT, Gemini, Claude). You upload a photo of the problem, choose a neural network, and get a solution. Plus, it has graphic tools and text generators. For serious calculations — Wolfram|Alpha, but it only supports photo input in the paid version.

I don't know, maybe everyone already knows this, but I thought it was useful. Solving problems from photos — it really works.
