Online brainstorming whiteboardSticky notes, mind maps and idea boards — free, no sign-up

Get every idea out of people's heads and onto the board. Add sticky notes in six colours, drag them into clusters, connect them into a mind map, and send the result around as an image or a link.

The Mind map template — one topic, six sticky notes, lines that stay attached.

Sticky notes on an online whiteboard

Press N (or pick the sticky note in the toolbar), click where the note should go and start typing — the note is ready for text the moment it lands. Long ideas are fine: the note grows to fit what you write.

  • Six colours — yellow, pink, green, blue, orange and purple — to sort ideas by theme, person or priority.
  • Fast duplicates: Ctrl + D copies a note, or hold Alt and drag to pull a copy off it.
  • Any size: drag the corner handles to make headline notes bigger than the rest.
  • Three fonts: hand-drawn, normal or code, in four sizes.

Make a mind map with connected ideas

Put the main topic in the middle — an ellipse works well — and branch ideas off it. Draw a line or arrow from the topic to each idea: the ends lock onto both shapes, so you can drag ideas around and the branches follow instead of breaking.

  • Use lines (L) for plain branches and arrows (A) where direction matters.
  • Switch an arrow to curved in the style panel for a softer, organic map.
  • Double-click an arrow to write a label on it — “because”, “blocks”, “depends on”.

Cluster and sort ideas (affinity mapping)

When the ideas are out, sort them. Drag a box around a set of notes to select them all, then move them together. Useful tools once a cluster forms:

  • Group (Ctrl + G) so a cluster moves as one piece.
  • Align and distribute from the style panel to line notes up into tidy columns.
  • Recolour a whole selection at once to mark a theme.
  • Name the cluster with a text heading above it (T).

Run a brainstorming session online

For a remote session, one person shares their screen and adds notes while the group talks — everyone sees the board fill up in real time on the call. Afterwards, send a share link so each person gets an editable copy to add to. The whiteboard has no live co-editing, so a single person at the keyboard keeps the session moving.

To vote, give each person a colour and have them add a small dot or tick with the pen next to their favourites, then count the dots.

Brainstorming templates: mind map, SWOT, retrospective and kanban

These starting points are one click away in the menu under Templates:

  • Mind map — a central topic with six sticky notes attached.
  • SWOT analysis — strengths, weaknesses, opportunities and threats in four quadrants.
  • Sprint retrospective — Went well, To improve and Action items, with dot votes.
  • Kanban board — To do, In progress and Done columns with notes to move across.
  • Project timeline — a roadmap with milestones, for planning what comes next.
  • Flowchart — for turning the chosen idea into steps.

A template is placed next to whatever is already on your board, never on top of it.

Keep and share the results

Export the board as a PNG for the meeting notes or a Slack thread, or as an SVG that stays sharp in a slide deck. Send a share link when someone should keep working on it, and use Save to file to archive the session as a .whiteboard file.

How to run a brainstorm on the whiteboard

  1. Write the question

    Type the problem at the top of the board with the text tool, so everyone answers the same question.

  2. Add one sticky note per idea

    Press N, click, type and repeat. Don't judge yet — quantity first.

  3. Cluster related notes

    Drag similar ideas next to each other, then select each cluster and group it with Ctrl+G.

  4. Name the clusters

    Add a short text heading above each group and recolour its notes to match the theme.

  5. Connect and decide

    Draw arrows between clusters that affect each other, and mark the winners with a pen dot vote.

  6. Share the result

    Export a PNG for the notes, or send a share link so the team can keep editing their own copy.

Brainstorming whiteboard FAQ

Sticky notes, mind maps and working with a team.

Is there a free online whiteboard with sticky notes?

Yes — this one. Sticky notes come in six colours, grow to fit their text and can be grouped, aligned and connected, all free and without an account.

Can my team add sticky notes at the same time?

Not live — the whiteboard has no real-time co-editing. Share your screen while one person adds notes, then send a share link so everyone gets an editable copy.

How do I make a mind map online for free?

Open the Mind map template, or put a topic in an ellipse, add sticky notes around it and draw a line from the topic to each note. The lines stay attached when you move things.

How do I change the colour of a sticky note?

Select the note (or several) and pick a new colour under Note colour in the style panel on the left.

Is there a limit on how many sticky notes I can add?

There's no fixed limit. The board lives in your browser, so the practical limit is your device — hundreds of notes are no problem.

Can I export a brainstorm as an image?

Yes. Export image in the menu downloads a PNG or SVG of the whole board or just the selected notes, or copies a PNG to your clipboard.
