Mind Maps Online: How Browser Mapping Works
Mind maps online are diagrams made in a web browser. A central idea sits in the middle, with main branches radiating outward and smaller nodes hanging from each branch. Because the map lives on the web, you can edit it, share a link and return to it from any device without installing software.
- Central topic: the core idea everything connects to
- Main branches: the major themes or categories
- Sub-nodes: supporting facts, examples and definitions
- Links between nodes: relationships across branches
- Notes and sources: details kept beside each node
Use a map to revise, plan or outline a project by collapsing and expanding branches. To build one from your own notes, CogniGuide generates a personalized mind map online from your files.
Mind Maps Online: Common Questions
Answers about browser-based mind maps and how CogniGuide builds them.
What is the difference between a mind map and a concept map?
A mind map radiates from one central idea in a tree-like layout. A concept map links ideas with labeled arrows, so the connections between concepts are explicit. Both help you see structure at a glance.
Do I need to install anything to use an online mind map?
No. Online mind map tools run in your browser, so you can open, edit and share a map without downloading software.
Which files can CogniGuide turn into a mind map?
You can upload a PDF, Word (DOCX) or PowerPoint (PPTX) file, a text or Markdown file, or an image. You can also type a topic instead.
Is it free to create a mind map online with CogniGuide?
Yes. The free plan includes 5 creations a week and needs no payment. Paid plans raise those limits.
