What it does
Bialborad provides a shared online canvas for teaching and team work. Its product page describes built-in video chat, screen sharing, presentation mode, file uploads, templates, exports, equation and graph tools, and a code editor. The vendor says the whiteboard is free. The page contains inconsistent classroom-size claims, listing both up to 50 and up to 100 students, so no specific capacity limit should be relied on.
Bialborad suits lessons and collaborative work where the board needs more than freehand drawing. The official page describes screen sharing and presentation mode alongside video chat, files, templates, exports, and subject-specific tools such as equations and graphs. It also mentions a code editor and tutoring use. The vendor says the product is free, but its page gives conflicting classroom-size claims of 50 and 100 students; avoid planning around a particular limit until the vendor clarifies it. Mobile access is mentioned, while Slack and Zoom integrations are described as upcoming rather than available.
