An AI tutor on an infinite whiteboard, not a chat thread
Gauth Unlimited Digital Canvas revolutionizes online learning by replacing traditional chat threads and slide decks with a continuous, spatial whiteboard. Designed for educators, students, and lifelong learners, it offers an immersive environment where lessons unfold on an expansive canvas, allowing for dynamic spatial arrangements of concepts, notes, and multimedia. As narration progresses, chapters expand side by side, and notes synchronize seamlessly with AI voice, creating a cohesive and interactive learning experience. Users can zoom from a broad concept map down to specific formulas, pause at any moment to interact with the AI Tutor, and receive immediate, on-board explanations. The ability to generate entire canvas-based lessons and export or share them as PDFs makes this an innovative tool for visual and interactive education.
