Sizzle AI

Sizzle AI (now branded Campus) is a free AI tutor that gives interactive, step-by-step help across math, science and other subjects, including from photos of problems.

Sizzle AI is an AI tutor aimed at students and lifelong learners who want to understand concepts, not just get answers. It breaks problems into manageable steps, answers follow-up questions and adapts to a learner's pace across subjects including math, physics, chemistry and biology, as well as humanities and test prep. Learners can upload a photo of a problem for the AI to analyze, making it easy to get help on homework. A distinguishing choice is that Sizzle has stayed free and unlimited, focusing on growth and learning quality rather than gating detailed steps behind a paid tier the way some competitors do. It was founded by Jerome Pesenti, a former Meta VP of AI, with a team drawn from Meta, Google and other technology companies. The app is now branded as Campus, an AI learning companion, in the app stores, though it is still widely known as Sizzle. Sizzle fits self-study, homework help and quick concept refreshers. Because it emphasizes interactive walkthroughs and critical thinking, it appeals to students who want guided practice rather than a black-box answer engine, though as with any AI tutor its explanations should be checked for accuracy.
