Built for the classroom

Every tool a teacher
actually needs.

Whiteboards, breakouts, polls, chat, and recording — crafted into a single, uncluttered experience that gets out of the way of learning.

A canvas every
student can touch.

The multi-user whiteboard turns any lesson into a collaborative space. Draw, annotate, and teach — together, in real time.

Small groups.
Big conversations.

Spin up breakout rooms in a single click. Hop between them, share materials, and bring everyone back when the bell rings.

Every lesson,
on replay.

Built-in recording captures audio, video, slides, and chat so students can revisit the moment — from any device, anywhere.

Engagement,
built in.

Polls, shared notes, emoji reactions, and raised hands — a toolkit for classrooms that hum, not classrooms that mute.
