What a digital whiteboard is for
A whiteboard is a freeform drawing surface: a canvas with pens, shapes, arrows, and text, and no imposed structure. That lack of structure is the point. Documents and slides force a sequence and a hierarchy before you know what you are explaining; a whiteboard lets the diagram develop as the thinking does.
Technically it is an HTML canvas that captures pointer input — mouse, trackpad, stylus, or finger — and renders strokes as you draw. Everything you produce lives in the browser tab until you export it as an image. That also means a whiteboard is a working surface rather than a document store: nothing is saved automatically, so anything you want to keep needs exporting before you close the tab.
Why we built this tool
Engineers sketch architecture and data flows, teachers explain a problem step by step, designers rough out a layout, and anyone in a call reaches for something to draw on when words are not working.
What ends up on those boards is unpublished system design, internal architecture, and half-formed ideas — the material most companies guard hardest. Collaborative whiteboard products store all of it on their servers under an account, indefinitely. Ours does the opposite by design: the canvas is local to your browser, nothing is transmitted, no account exists, and when you close the tab the drawing is gone unless you exported it. It is a scratchpad that leaves no trace, which is exactly what a scratchpad should be.
Tips and common mistakes
- Export before closing the tab — nothing is stored on a server, so an unexported board is gone.
- Use consistent colours for consistent meanings, such as one colour for infrastructure and another for data flow.
- A stylus or trackpad gives far better strokes than a mouse for freehand work.
- Sketch the rough shape first and label afterwards; labelling too early tends to freeze the diagram.
Quick start: using Online Whiteboard
- Open the whiteboard and pick a pen, shape, or text tool.
- Draw with your mouse, trackpad, or stylus — a stylus gives the most natural result.
- Use colours to separate layers of the diagram as it grows.
- Undo and erase freely; nothing is committed until you export.
- Export as an image before closing the tab, because the board is not saved anywhere.
Add labels and callouts to the exported picture with Annotate Image, or capture written notes alongside it in Note Editor.
