Mavea turns AI answers into a living canvas: charts, timelines, maps, and evidence you can check, drawn in real time as it talks. Draw back to ask: circle a number, cross one out, or drop a question mark, and the next answer grounds on that exact spot. Runs on your machine with your own API key (Claude, GPT, Gemini, Grok, or OpenRouter). No signup, no install required. Try it: npx @mavea/mavea@latest. Code and docs: github.com/TryMaveaAI/mavea
