ThinkBoard AI is a whiteboard with an AI tutor that helps you think through problems instead of just giving you the answer. You write or draw your work on an infinite canvas, and the tutor looks at what’s on your board. It can check your work, give a hint, or suggest a next step, and it highlights the exact line it’s talking about with a popup answer beside it. It uses Meta’s Muse Spark to read your board and respond, and it explains the concept rather than solving the problem for you. Ask it to draw something (“make a graph for the rejection region”) and it plans the diagram first. Graphs and distributions are drawn exactly by the app, technical figures are drawn as clean SVG, and Muse Image is used for pictorial topics like the water cycle. You can speak your questions with Muse Voice Transcribe, with live captions as you talk, and stop the AI at any point. The app has a light/dark theme, a graph builder you can edit later, and math-friendly text with fractions and symbols. Study questions stay on topic, and a spending cap keeps the paid AI calls in check.
