About penecho

Think with AI beyond the chat box. PenEcho is a shared canvas where handwriting, equations, diagrams, and spatial context become part of the conversation. Think on the canvas Put a question, equation, diagram, or half-formed idea anywhere on the canvas and pause. PenEcho reads your marks and their spatial relationships, then answers beside them. You can work through a problem without translating every step into a chat message or rebuilding it with rigid diagram tools. Get answers, hints, explanations, continuations, formulas, plots, and diagrams directly on the canvas.
