Querion AI the math solver app

Querion AI is a learning support app that allows you to simply upload a photo of a math problem taken with your camera (or from your photo library), and the AI will instantly analyze and solve it for you. With detailed step-by-step explanations, it not only gives you the answer but also helps you deepen your understanding.

Now, in addition to math, Querion AI also supports English-related learning, including grammar checks, sentence structure correction, translations, and English composition proofreading. Furthermore, the newly added “Any Image Explanation” feature enables the app to interpret and solve a wide variety of problem images—even beyond math and English—providing support across multiple subjects.

It covers everything from junior high and high school math to university-level problems, including national standardized tests and entrance exams. Whether it's calculations, proofs, English grammar or vocabulary questions, sentence arrangement tasks, writing corrections, or translations, Querion AI is a multi-subject learning assistant that supports all types of academic questions.
