Why Use an Online Whiteboard?

Physical whiteboards are great, but they don't scale. Our digital solution offers:

Use Cases

1. Remote Teaching & Tutoring

Teachers can share their screen and use the whiteboard to explain math problems, draw chemical structures, or map out history timelines. The freehand pencil tool works great with tablets.

2. Software Architecture

Developers love our "Mermaid JS" integration. You can type code to generate clean flowcharts and sequence diagrams, then annotate them with freehand drawings.

3. UX Wireframing

We've included presets for iPhone, Tablet, and Desktop frames. Drag and drop basic shapes to create low-fidelity wireframes for your next app.

How to Use the Whiteboard

  1. Open the tool.
  2. Press S or click the Sticky Note icon to drop an idea.
  3. Press P to switch to Pencil mode and draw connections.
  4. Use the mouse wheel to zoom in and out.
  5. Click Export PDF to save your session as a document.
