Whiteboard by Endless AI

Whiteboard by Endless AI is a digital whiteboard aimed at people who explain things for a living — tutors working over a video call, parents walking a child through a long-division problem, coaches drawing up a play. It handles handwriting and typed notes side by side, and lets you switch between discrete pages, which suit a structured lesson, and an infinite canvas, which suits a topic that keeps expanding. On an iPad it supports Apple Pencil input; on a desktop it works with a mouse or a graphics tablet.

The feature homeschool families are most likely to care about is PDF import and annotation. A great deal of homeschool material arrives as a PDF worksheet or a scanned page from a manual, and being able to pull that straight onto the board, write over it, and then export or share the marked-up result removes a printing step from the day. Shapes, arrows and text boxes are available for diagramming, and finished boards can be exported or shared.

Its genuine differentiator is platform coverage. It runs on iPhone, iPad, Android, Mac, Windows and Linux, including Linux packages for both x86_64 and ARM64 — which is unusual, and matters for families running Chromebooks-turned-Linux boxes or older hardware that newer apps have dropped. A separate mode provides sports tactics boards with numbered players on court and field templates, useful if you also coach.

Points to weigh before committing. Download is free, but optional paid features vary by platform, so what you get for nothing on Android may not match what you get on iPad — check the store listing for your device rather than assuming. This is a tool, not a curriculum: it teaches nothing on its own and contains no lesson content. And as a relatively young product from a small developer, it does not have the long track record or the large community that established whiteboard apps have built up. Worth a trial precisely because trying it costs nothing.
