An infinite online whiteboard for teams
Sketch, map and plan on an infinite canvas with shapes, connectors, sticky notes, rich text, frames and pages — fast enough for thousands of objects.
Why teams use it
Type anywhere
Double-click empty space for text, or double-click any shape to write a centred label inside it. Press Enter on a selection to edit.
Shapes that connect
Rectangles, diamonds, clouds, cylinders and more, joined by straight, curved or elbow arrows that stay attached as you move things.
Sticky notes that think
Brainstorm on stickies, then turn the good ones into real tasks with one click.
Frames and pages
Group work into frames, split big boards into pages, and keep every idea one zoom away.
Built for scale
Spatial indexing and viewport culling keep large boards smooth on a laptop.
Works offline
Edits save locally first and sync when you are back online.
How it works
- 1Open a blank canvas or start from a template.
- 2Draw with the toolbar or single-key shortcuts (R, O, D, A, T).
- 3Share the link and keep working together.
Questions
Is Planloom a whiteboard or a diagramming tool?
Both. Freehand sketching, sticky notes and diagramming primitives live on the same infinite canvas, so a brainstorm can become an architecture diagram without switching apps.
How does it compare to tldraw or Excalidraw?
The editing feel is similar — fast shortcuts, double-click to type, snappy shapes — but the canvas is connected to your team’s tasks and GitHub, and every board is collaborative by default.
Can I export my work?
Yes. Export boards as PNG, SVG or JSON, or present them straight from the canvas.
