Yes — sign up free with just an email. Every new account gets 50 starter credits to try the AI, and your trees are saved to your account across devices. You can browse the Library without an account.

It's free to try. Every new account gets 50 one-time starter credits — enough to grow a couple of trees and see how it feels. They don't renew. To keep working with AI you pick a plan, and every plan starts with a 7-day free trial. Trees you build and edit by hand are always free.

Anything you'd brainstorm on a whiteboard — product names, content outlines, project plans, research angles, lesson ideas, trip itineraries. You type a topic and the AI grows it into a branching tree of ideas you can prune, re-grow, and reshape until it's yours.

Grow asks the AI to branch a topic into related ideas. Each new branch is aware of the rest of your tree, so the suggestions stay on theme instead of drifting. Grow any node to go a level deeper.

Pruning is deleting the branches you don't want, so the tree reflects only the directions worth keeping. Re-growing takes a branch you like and expands it further. The loop — grow, prune, re-grow — is how a rough topic turns into a focused set of ideas.

Yes. The built-in assistant chat can add, rename, reorganize, and grow branches for you — just describe what you want. Every change it makes is fully undoable, so you can experiment freely and step back if a direction doesn't work out.

Yes. Voice mode lets you talk through ideas instead of typing — handy when you're thinking out loud or working hands-free — and the tree grows from what you say.

Both. The canvas view shows your ideas as a visual, spatial tree you can pan and explore; the outline view shows the same tree as a structured, top-to-bottom list that's easy to read and copy. Switch between them anytime — it's the same tree, two ways of seeing it.

Three monthly plans — Starter, Pro and Max — with the same product on every one. They differ only in how many credits are included each month, and the bigger plans get more credits per dollar. Every plan starts with a 7-day free trial: add a card, nothing is charged until the trial ends, cancel before then and you pay nothing. See pricing for the numbers.

Credits measure AI work — a heavy request costs more than a light one, so you only spend what you use. Every plan includes a monthly balance that refills on renewal; if you need more before then you can add credits any time. Any amount from $10 to $500, at 20 credits per dollar. Top-ups are one-time, never expire, and aren't refunded if you cancel.

Yes. Cancel during the free trial and you're never charged. Cancel later and you keep your plan through the end of the period you've paid for. Credits you bought as top-ups stay on your account and aren't refunded. For billing questions, reach out via support — full terms are in our Terms.

When your starter credits or your plan's credits run out, AI pauses and we'll let you know — your trees stay fully intact, and you can keep editing them by hand. Starter credits don't renew; start a plan (with a free trial) to keep going, and on a plan you can add credits any time.

We don't sell your content, and our aim is to keep your trees yours. Because the specifics matter, please see our Privacy Policy for exactly how data is handled, including anything related to model training.

Yes. Trees you create are private to you unless you choose to share them. Sharing is always an explicit action. Details are in our Privacy Policy.

You can share a tree with a link so others can explore it — and stop sharing it whenever you like. You stay in control of what you share and when.

Yes. Export any tree as Markdown, a Word document (.docx), a PDF — as shown on screen, or with every branch expanded — or JSON, and save a guided tour of a tree as a video. Your chat with the assistant exports as Markdown. A JSON export can be imported back in, to restore a tree or move it to another account.

Treat AI-generated ideas as starting points, not final answers. They're meant to spark thinking and can be incomplete or wrong, so review anything important before acting on it. See our Privacy Policy and Terms for more.
