Step-by-Step: Build Your Mind Map

Follow these steps to create a complete mind map from scratch.

Open the Whiteboard and Plan Your Space

Go to onlinewhiteboard.org — no account needed. The canvas is infinite, so you have all the space you need. Before placing anything, think about your central topic and roughly how many main branches you'll have. Mind maps with 4–8 main branches work best visually.

Place Your Central Topic in the Middle

Click the Sticky Note tool and click roughly in the centre of your canvas. Type your main topic — this is the core idea everything branches from. Use a bold colour (yellow or orange) to make it visually dominant. You can also use the Text tool inside a shape if you prefer a different look.

Add First-Level Branch Nodes

Place sticky notes around the centre — above, below, left, right, and diagonals. Each one is a main subtopic. Use a different colour per branch — for example, blue for one branch, green for another. This colour-coding is key to making the map readable at a glance.

Colour tip: Assign one colour per branch and keep that colour for all its child nodes. This makes the hierarchy obvious without needing extra labels.

Connect Nodes with Arrows

Select the Arrow tool from the toolbar. Click and drag from the edge of the central node to the edge of each branch node. Repeat from each branch node to its sub-nodes. The lines radiate outward — this is the defining structure of a mind map.

Add Second and Third Level Ideas

Branch further outward from your first-level nodes. Add smaller sticky notes (or just text labels) for supporting ideas, details, and examples. Keep the same colour family as the parent branch. Second-level nodes can be smaller and use a lighter shade if you want visual hierarchy.

Add Images if Relevant

Use the Image Upload tool to add photos, diagrams, or icons directly onto the canvas near relevant nodes. Visual cues improve memory and make the map more engaging — especially useful for revision maps and study guides.

Export Your Finished Mind Map

Click PDF or PNG in the toolbar. Your entire canvas is captured — no watermark, no account needed. PDF is best for printing or sharing as a document. PNG is better for embedding in presentations or sharing as an image.

Mind Map Layouts — Which Structure to Use

Different arrangements suit different types of thinking.

🌐

Radial (Classic)

Central topic in the middle, branches radiating outward in all directions. Best for brainstorming and exploring a topic freely — no hierarchy implied by direction.

🌳

Tree (Top-Down)

Central topic at the top, branches flowing downward like a tree. Better for hierarchical content like organisational charts, decision trees, and structured outlines.

➡️

Linear (Left-to-Right)

Central topic on the left, branching rightward in a timeline or process flow. Useful for sequences, processes, and timelines where order matters.

Which to choose: For pure brainstorming and idea generation, use radial — there's no implied order or priority. For planning or structured thinking, use tree or linear.

Mind Mapping Tips for Better Results

Small habits that make a big difference to mind map quality.

Use single words or short phrases per node — not full sentences. The brevity is what makes mind maps scannable. If you need detail, add it as a sub-branch rather than a long label.

Start with quantity, refine later — in the first pass, add every idea that comes to mind. Don't edit yourself. Then in a second pass, reorganise, delete, and group related nodes.

Limit each branch to 5–7 direct children — more than that makes the branch hard to read. If a branch grows too large, consider making one of its nodes its own sub-centre.

Save frequently — click the Save button to download a project file as you work. This lets you restore any earlier version if you want to undo a restructure.

Frequently Asked Questions

What's the difference between a mind map and a concept map?

A mind map radiates from a single central topic outward, with one hierarchy. A concept map links multiple concepts with labelled relationships in any direction — more of a network than a tree. Use a mind map for brainstorming one topic; use a concept map for showing relationships between multiple ideas.

Can I share my mind map with someone else?

Export it as a PDF or PNG and share the file. You can also screen-share the whiteboard during a video call so others can see it live as you build it.

How many levels of branches should a mind map have?

Most effective mind maps have 2–3 levels: central topic → main branches → sub-branches. Going deeper than 3 levels usually means you need to split the map into multiple maps or use a different format.

Can I edit a mind map after exporting it?

Yes — save the project file (.owb) to your device before exporting. You can reopen it in the whiteboard and continue editing. The PDF and PNG exports are static images — only the project file is editable.
