Brainiac

Brainiac is a free learning extension that helps students understand problems across subjects like SAT Math, SAT English, physics, calculus, and more. It can scan your screen, read problems, accept typed or pasted questions, and let users upload screenshots. After the user chooses their level of understanding, Brainiac creates a clear, step-by-step visual video with a voiceover explanation. If a student is confused about a specific step, they can generate another video that explains that part in more detail. Explanations can also be saved to files or stored in a personal library for later review.
