The tool
Your whiteboard
Sketchboard
Open full screen ↗Privacy-first: your files are processed in your browser and never uploaded. The few tools that need a server — running C, C++, Java or Python code, reading a public web page, or a speed test — send only what you enter for that job.
Who it's for
Made for the people who actually use it.
Teachers & trainers
The pain
Explaining a flowchart or a network on screen needs something faster than slides and lighter than design software.
The outcome
Draw boxes and arrows as you talk, then export the board to share with the class.
Students
The pain
Assignments and projects need neat block diagrams and flowcharts, but shapes in Word are fiddly.
The outcome
Rectangles, diamonds and arrows that make a clean diagram, exported as an image.
Developers & designers
The pain
A quick architecture sketch or wireframe does not deserve a paid whiteboard subscription.
The outcome
A fast canvas with keyboard shortcuts and a saved file you can reopen anytime.
