Online Whiteboard

A real-time collaborative whiteboard that holds up under 20+ students drawing at once. Classroom-friendly tools — manuscript paper, post-its, stickers — come standard, alongside subject-specific custom objects and digital-textbook sync. Proven in live AI Digital Textbook lessons.

Online Whiteboard

A real-time class lives or dies on uninterrupted collaboration.

In a live class, the experience that matters most is teachers and students drawing and writing together on the same board. The moment that experience breaks, the flow of the class breaks with it.

We built a real-time collaborative whiteboard around our own WebSocket-based synchronization engine. A class of 20+ students drawing at full speed stays consistent and uninterrupted on the same board.

It's a tool proven in MiraeN's live AI Digital Textbook classes. Manuscript paper, post-its, stickers, and subject-specific custom objects — the variety of classroom activities all live in one place.

So that live class flow stays unbroken

A live-edit engine, classroom-ready tools, and connections to subject content and the digital textbook.

WebSocket real-time collaboration

An in-house WebSocket-based synchronization engine. Many users on the same board, drawing at the same time, stay in a consistent state.

Validated at 20+ concurrent

Validated in MiraeN's live AI Digital Textbook classes — 20+ students drawing fast on the same board, with no degradation.

Classroom-ready tools

Manuscript paper, post-its, stickers, and other tools teachers actually use — included by default. The familiar feel of paper worksheets, on a digital board.

Subject-specific custom objects

Math shapes, science lab tools, vocabulary cards, and more — domain-specific objects can be developed and added to the board. Subject-aligned learning activities stay natural to use.

Background add-ons

Scenario-specific backgrounds delivered as add-ons. Grid, coordinate planes, music staves, maps — teachers stop redrawing the canvas every time.

Data history & textbook sync

Per-class board history accumulates over time, and the board can sync with digital textbook pages. After-class records become a real learning asset.

Live whiteboard for the AI Digital Textbook classroom

MiraeN uses our online whiteboard as a core tool in live AI Digital Textbook classes. We built an in-house WebSocket synchronization engine so that 20+ students drawing at full speed never see a hiccup, and delivered classroom-ready tools — manuscript paper, post-its, stickers — alongside subject-specific custom objects.
