Nodea

Nodea is an AI branching chat canvas that replaces the standard linear conversation thread with a tree-based interface for anyone using Claude to think, write, or research. Instead of scrolling through a single thread and losing earlier replies when you edit a prompt, Nodea turns every AI response into a node you can fork — creating a map of every path you have explored. Built natively on Anthropic Claude (Haiku 4.5, Sonnet 4.6, and Opus 4.7), the tool lets you open a branch from any message, keep the original response untouched, and compare both answers side by side on a zoomable canvas.

Core features include one-click branching from any node, a full-canvas view where you can drag and zoom across your conversation tree, color-coding to tag the answers worth keeping, and a global search (⌘K) that reaches every node across every branch simultaneously. An anonymous mode lets you try the canvas without creating an account or entering a credit card.

Nodea is the best AI thinking canvas for writers, researchers, and developers who routinely iterate on prompts and need to compare multiple AI responses without starting a new chat each time. It is MIT-licensed and the source is publicly available on GitHub. The tool is free during beta, with a Pro plan at $8 per month for users who want continued access after the beta period ends.

Nodea is used for branching AI-assisted thinking, writing, and research by individuals who want to explore multiple prompt directions simultaneously without losing earlier Claude responses. It is suited to writers, developers, and knowledge workers who iterate heavily on prompts and need a visual map of their conversation history.
