Why teachers use an online whiteboard

• Visual explanation: sketch diagrams, work through math problems, and annotate as you teach.
• Screen sharing friendly: share your screen on any video call and draw live.
• No setup time: the board opens instantly, so no class time is lost.
• Save lessons: export the board as an image to share with students afterward.
• Works on tablets: pair it with a stylus for natural handwriting.

How to teach with the whiteboard

Open the board, choose a dark pen color for clear visibility, and use the text tool for headings. Use shapes and arrows to build diagrams, and the eraser to correct work in real time. When the lesson ends, click Save PNG to keep a copy of everything you covered.

Great for every subject

Math teachers solve equations step by step, language teachers diagram sentences, science teachers sketch processes, and tutors annotate student work. Because the canvas pans and zooms, you never run out of room mid-lesson.
