Lessons and tutoring
Work through equations, diagrams, vocabulary, and examples in real time with visual structure.
Sketch ideas, teach visually, map a process, and work through technical details on a full Windows whiteboard with custom backgrounds, grid mode, precision tools, session saving, and crash recovery.

Drawing, text, shapes, focus aids, and precision tools stay close to your workspace.
Use the whiteboard independently or alongside OS Pen's screen annotation tools for teaching, presenting, planning, and technical communication.
Work through equations, diagrams, vocabulary, and examples in real time with visual structure.
Sketch flows, group ideas, number steps, and keep a shared explanation easy to follow.
Combine grid mode, ruler, protractor, shapes, and labels for geometry and precise diagrams.
Start with an open canvas, then add the background, grid, tools, and recovery options the session needs.
Build a visual explanation with freehand drawing and structured annotations in the same workspace.
Choose a suitable board background for lessons, diagrams, planning, or presentation material.
Add consistent visual spacing when working with charts, layouts, geometry, and aligned notes.
Use supported precision instruments to demonstrate angles, measurements, and technical construction.
Save supported board sessions so important work can be continued or revisited later.
Recoverable workspace support helps protect progress after an unexpected interruption.
Prepare the board for the topic, add the right tools, and save the session or capture the result.
Launch the full whiteboard and choose a clean, custom, or grid-based background for the task.
Use ink, highlights, shapes, text, numbering, ruler, or protractor as the explanation develops.
Save the supported session for later or capture the visual result for notes, training, and follow-up.
