Nodea is a branching canvas for Claude that turns every reply into a node you can fork. Ask the same question a different way, compare both answers side by side, color-tag the keeper, and the path you didn't take stays exactly where you left it. The whole conversation grows as a navigable tree, not a scroll. That model works well for research drafts, planning alternatives, and iterative prompt work — but Nodea is a single-model interface locked to Anthropic Claude. Teams that need GPT-4o, Gemini, or their own fine-tuned model will hit that wall on day one.
