Slides for teachers and tutors, with live audience interaction.
Build a lesson deck, press Start, and the class joins from their phones with a short code. Polls, quizzes, word clouds, rankings and Q&A sit on the slides they belong to, and results appear on the projector as people answer. Tutors also keep lesson notes, set homework, and give each student a private link to their practice and feedback.

- Deck editor with layouts, themes, reveal order, speaker notes and version
history. Runs in the browser, or offline in the Desktop app on local
.openroomfiles. - Live sessions: phones join with a code or QR, no app or account needed. Polls, multiple choice, word clouds, rankings, open text, fill-the-gaps and moderated Q&A.
- Presenter view with answer controls, results shown as bars or clouds, and a second display for the stage.
- Tutoring workflow: students and classes, notes after each lesson, homework and practice, and a private learner page with returned work.
- Agents built in: the Desktop app has an agent sidebar that edits the open deck
("add a slide with a picture of a cat"). The same tools are available to any agent
through the
openroomCLI and an MCP server. - PowerPoint add-in that puts OpenRoom questions and session controls inside PowerPoint.

OpenRoom deploys to your own Cloudflare account, either the relay alone for live
sessions without accounts, or the full app. A deployment without billing configured
has every feature unlocked. See docs/SELF-HOST.md.
The core (packages/, the relay, stage, participant, Office and Desktop apps) is
MIT. The workspace (apps/workspace,
apps/workspace-worker, apps/site, e2e/) is AGPL-3.0.
