A mind map maker is a tool for drawing a central idea with related ideas branching out from it. Type your idea, add branches with Tab and Enter, drag to rearrange, color-code and collapse branches, then export a PNG, SVG, PDF, or outline. Start from a template to map a business idea, a product, or a marketing plan.

Your map saves automatically in this browser. Images and PDF show the map as it looks now, so collapsed branches stay hidden. Markdown and OPML always include every branch.
Ways to use it
Select the box in the middle and type the problem, product, or decision you want to think through. Start from a template or a blank map.
Press Tab to add a branch under an idea and Enter to add one beside it. On a phone, use the Add branch and Add sibling buttons.
Drag an idea onto another to nest it, or onto the top or bottom edge of one to place it beside that idea. Pick a color for each main branch and collapse what you're not working on.
Download a PNG, SVG, or PDF for a deck or document, export a Markdown or OPML outline, or copy a link that holds the whole map.
Common questions
A mind map is a diagram that puts one central idea in the middle and branches related ideas out from it. Because each branch can split into smaller ones, it shows how thoughts connect, which makes it useful for brainstorming, planning, and note-taking.
Yes. There is no signup, watermark, or paid plan. You can make as many maps as you like, each with up to 300 ideas, and export them in any format.
Your map saves automatically in this browser's local storage and isn't uploaded to Idea Score. It reopens when you come back on the same device and browser, but clearing site data removes it, so export anything you want to keep. The tool keeps one saved map at a time.
The share link holds the entire map inside the link itself, so there is no account or server copy. Anyone who has the link can see the map and edit their own copy, and your original doesn't change. Very large maps make long links that some chat apps may cut off, so export OPML or Markdown for those.
Use PNG for slides and chat, SVG for artwork that stays sharp and can be edited in design tools, and PDF for printing on a Letter page. Those three show the map as it looks now, with collapsed branches hidden. Markdown and OPML outlines always include every branch, and OPML can be imported by outliner apps that support the format.
Start with the business idea template and fill in the problem, customers, competitors, channels, revenue, and risks. Empty or vague branches show what you don't know yet. Turn those gaps into questions to test with real customers, starting with your riskiest assumption.
