Why most free mind map tools do not feel free
Many free plans add friction right when you need to think quickly: account gates, map limits, export restrictions, or watermarks.
| Common problem | What happens | MindKey |
|---|---|---|
| Free plan limits | Only a few maps, storage caps, or paid export options | Unlimited maps and watermark-free exports |
| Signup friction | Email or social login before you can even start | No account required |
| Slow input | Create nodes with buttons, drag them around, then type | Keyboard-first editing with automatic layout |
| Export mismatch | The exported image differs from the canvas preview | The same SVG pipeline powers screen and export |
Three keys are enough to grow the tree
Create a child with Tab, add a sibling with Enter, and move back up with Shift+Tab. Each new node is focused immediately, so your hands stay on the keyboard.
Keyboard-first flow
Fast note capture for meetings, study plans, writing outlines, and brainstorming.
Private by default
Your maps stay in browser storage. Use JSON export when you need a backup.
Portable exports
Export PNG, SVG, Markdown, OPML, and JSON without a watermark.
Frequently asked questions
Is there really no signup?
Yes. MindKey does not ask for email, social login, or an account.
Can I make unlimited maps?
Yes. Maps are stored locally in your browser, so MindKey does not need a map limit.
Will exported files have a watermark?
No. PNG, SVG, Markdown, OPML, and JSON exports are watermark-free.
Can teams edit together?
No. MindKey focuses on fast solo thinking, not real-time collaboration.
