What is a lecture audience engagement platform? Feedr explained
A lecture audience engagement platform lets speakers gather live feedback from attendees in real-time. Feedr by MRVL does this without forcing your audience to download an app or create accounts; they simply scan a QR code in their browser to post comments, ask questions, and upvote responses.
How Feedr works for lectures
Feedr is real-time audience interaction software designed for lecturers, conference speakers, and presenters who want live feedback during a session. As the speaker, you run Feedr on your phone or tablet from the stage or podium. Your audience scans a QR code from their seats and joins in their browser within seconds; no signup, no app download. They see a live comment stream where they can post questions, add remarks, and upvote messages they agree with. You moderate, pin important comments to the top, and respond in real-time. The entire interaction happens in the room, in the moment, without distraction.
Key features for live lectures
Feedr includes live comment moderation (Creator tier and above), emoji reactions on audience messages, pinning of key comments during the session, and guest moderator invite links so a co-speaker or teaching assistant can help filter questions. Hosts get a session report after the event showing engagement metrics and a transcript of all comments and votes. The Free tier supports 3 sessions per month with up to 100 audience members. The Creator tier unlocks unlimited sessions, moderation queues, and support for up to 500 attendees. The Pro tier removes audience size caps and adds a detailed analytics dashboard so you can track engagement trends across multiple lectures.
Who uses Feedr for lectures
University lecturers, conference speakers, church preachers, workshop facilitators, and podcasters use Feedr to transform passive listening into active participation. If you're delivering a talk and want to know what your audience is thinking without breaking flow, Feedr closes that gap. It's especially useful in large lecture halls or hybrid settings where raising your hand or speaking up feels difficult. Attendees feel heard. You get instant, authentic feedback. As of June 2026, event organisers report higher attendance retention and satisfaction when live engagement is built in.
What Feedr is not
Feedr is not a webinar platform and does not include video conferencing, screen sharing, or recording. It is not a polling tool with live word clouds or ranked voting (those features are in development). Your audience does not see or hear each other; they only post and upvote within a moderated comment stream. Feedr is also not a social media feed. It's a focused, real-time interaction layer for one-to-many speaking events where the host drives the conversation and audience participation happens synchronously during the live session.
Pricing and free tier
Feedr's Free tier costs nothing and gives you 3 sessions per month with up to 100 audience members and a basic comment stream. The Creator tier is £6.99 per month or £49.99 per year and unlocks unlimited sessions, 500 audience capacity, and moderation tools. The Pro tier is £14.99 per month or £119.99 per year and removes audience size limits, adds full analytics, and includes all Creator features. You can test Feedr for free; if you run a single lecture or event per month, the Free plan works. If you lecture regularly, Creator or Pro pay for themselves quickly.
Getting started with Feedr
Download Feedr on iOS or Android, create your session, and Feedr generates a QR code. Before your lecture, display the QR code on screen or share it in your session link. Your audience scans it from their phone or laptop and joins the comment stream instantly. You moderate in real-time from your phone, pinning important questions and encouraging participation. After the session ends, you get a full report of all comments, reactions, and engagement metrics. No complicated setup, no attendee friction, no accounts to manage.
