What is Nodea?
Nodea is a branching AI chat canvas. Every reply becomes a node you can fork from. Your conversation grows as a tree of branches, not one long thread. Built on Anthropic Claude (Sonnet 5, with Opus on Pro).
Don’t like an answer? Branch and ask again. The original stays put, right next to the new path.

See your AI chats as a tree.
Every edit and regenerate hides a branch. Nodea Tree draws that hidden tree right beside your chat on claude.ai and chatgpt.com — and lets you branch without leaving the page. One click imports the whole tree into Nodea, where you can fork, compare, and keep working.

Every thought you've had,
without losing any.
One thread, scrolling forever.
Edit a prompt and the old reply vanishes. Try a different angle and you fork into a new chat. Context gets lost between tabs.
A map of every thought you've had.
Branch from any message to explore an alternative. Compare answers side by side. Color-code the keepers. Search across every path at once.
Built around the idea
that thinking forks.
Every feature exists to make branching feel natural, not bolted on.
Branch from any message.
Hover a reply, hit branch, ask the question a different way. The old path stays put. You explore in parallel instead of starting over.
See your thinking, not just your scroll.
Every conversation becomes a live tree. Drag, zoom, jump to any node. Your thinking takes a shape you can see and edit.
Color-code the keepers.
Tag the answers worth remembering. Skim a project at a glance.
Search across every path.
One ⌘K, every node, every branch. The good thought is never more than a keystroke away.
Three motions. That's it.
Start a conversation
Type a question, a problem, a half-formed idea. Claude answers.
Fork any moment
Hover any message and hit branch. A new path opens; the original stays where you left it.
Jump between paths
Click any node to switch paths instantly. Full history, no scrolling.

See Your Claude Conversations as a Tree (Free Chrome Extension)
Claude.ai hides a branch tree behind every chat you edit or regenerate. The free Nodea Tree for Claude extension draws it beside your conversation — and imports the whole thing into a canvas you can fork and merge.
How to Branch a Chat in Claude (See the Hidden Tree)
Yes, you can branch a chat in Claude — it already forks every time you edit or regenerate. Claude just hides the tree. Here are the two built-in tricks, their limits, and a free extension that shows every branch.

What does Nodea do?
Nodea lets you chat with Anthropic Claude on a branching canvas instead of one linear thread. Every reply becomes a node. Fork any node to ask the question a different way, explore an alternative, or compare two answers side by side without losing the original path.
What is branching AI chat?
Branching AI chat is a conversation interface where each message is stored as a node in a tree. From any node you can start a new branch: a separate path that explores an alternative without overwriting the original. Linear chatbots (ChatGPT, Claude.ai) only let you append, edit, or start over.
Why would I use Nodea instead of ChatGPT?
Nodea is the better tool when you want to explore alternatives (different tones, framings, or plans from the same starting point) without losing any of them. ChatGPT is the better tool for a single linear question-and-answer session, or when you need OpenAI-specific features like image generation. Nodea Pro is $24/mo — a few dollars more than ChatGPT Plus at $20/mo — but you’re paying for the branching canvas and Claude Opus, not a cheaper linear chatbot.
Can I try Nodea without signing up?
Yes. Nodea supports anonymous sign-in: a real account with no email address required. Open a canvas, branch, and save projects immediately, then link an email later to claim your data.
How much does Nodea cost?
Nodea is free during beta with 50,000 daily / 500,000 monthly tokens on Claude Sonnet 5. The Pro plan is $24/month and unlocks Claude Opus, a 300,000 daily / 3,000,000 monthly token budget, and early access to new features. Cancel anytime.
Which AI models power Nodea?
Nodea runs on Anthropic Claude: Sonnet 5 powers every conversation, and Pro routes the heaviest tasks to Opus. The model is selected automatically based on prompt complexity and your plan tier.
Is Nodea open source?
Yes. The Nodea source is MIT-licensed and available on GitHub. The hosted product runs at nodea.ai; you can self-host the same codebase against your own Supabase project and Anthropic API key.
