Every AI chat forces one linear thread, so a single follow-up buries the path you actually wanted. Nodea moves the conversation onto a canvas. Each reply becomes a node, and you can fork from any node to explore a new direction while the original stays intact. Compare answers side by side, keep parallel branches alive, and see your thinking as a tree instead of an endless scroll. Runs on Claude Haiku, Sonnet, and Opus. Free to start, Early Access Pro is $8 a month (forever price).
