Euiyun Live
A real-time Q&A platform where seminar and training audiences join instantly with no sign-up. Questions, polls, and live reactions all in one place.
Overview
At seminars, talks, and training sessions it is hard to collect audience questions and opinions on the spot. Raising a hand feels intimidating, and separate survey tools require sign-ups and link sharing.
Euiyun Live lets the audience join instantly with just a room code or QR — no account needed. Questions are ranked by upvotes, and presenters open multiple-choice or open-ended polls to gauge understanding and reactions in real time.
Features
- Instant join with a room code or QR — no sign-up
- Question upvotes — the questions the audience cares about rise to the top
- Open multiple-choice and open-ended polls to collect live responses
- Stage (projector) view — highlights the active question or poll
- Schedule, timers, and live emoji reactions
- Built-in seminar/training survey templates, including AI familiarity
