Check your homework with AI from a photo

You solved the problem but don't know if it's right. With Dottya you take a photo of your notebook and the AI checks your work step by step: it tells you which steps are right, where you went wrong and why, and gives you a hint so you fix it yourself instead of handing you the answer.
