The AI audience engagement lead for conferences.
One QR code on the badge, the lanyard, the slide. Attendees scan and they're in — asking, voting, posting, chatting. No app to download. No account to make. No event code to mistype.
The conference engagement tax
Conference engagement tools have been quietly broken for a decade. The forced app install kills participation before the keynote starts. The 6-digit codes get mistyped. The "engagement" you do measure is mostly your own staff. The questions in the room never make it to the speaker.
By the time someone has found the app on the App Store, agreed to push notifications, made an account, and confirmed an email — the keynote has started. Most don't bother. You're left engaging the 11% who did.
"Go to slido.com and enter code XJ4-K91." Half the room mistypes it. A third end up at the wrong event. The MC repeats it three times from the stage and you can feel the energy drain out of the room.
Q&A in Slido. Polls in Mentimeter. Schedule in Whova. Networking on a Slack workspace that nobody joins. Five tools, five logins, attendee fatigue by the coffee break.
The best conversations happen at the coffee station, between two people who'd never have met without each other physically being in the room. None of it makes it back to the rest of the attendees, the speakers, or you.
The QR code moment
ReactLive is a web surface, not an app. One QR code in the venue points to your event. Attendees scan with the camera they already have open, and they're inside the chat — typing, voting, posting — before the next slide. Engagement rates climb because the friction is gone.

One QR, two modes
Print one QR on every session slide for talk-by-talk Q&A. Or print one on the badge for the whole event — attendees stay in the same chat from keynote to closing party. The organiser picks. Same product, two shapes.
Talk-by-talk
Each session is its own room. Q&A and polls scoped to one talk. Best for multi-track events.
One persistent chat
One badge QR, three days of conversation. Sessions, hallway chat, announcements all in one surface.
The Auto-Answer Loop
Conferences don't fail because the audience has nothing to say. They fail because eight hundred questions arrive and a moderator can't read them all. ReactLive clusters incoming questions, matches them against three answer sources, and resolves most of them automatically — so the moderator spends time on the questions that actually need human judgement.
The speaker covers rate limits at 14:08. Three minutes later, four new attendees ask about rate limits. ReactLive matches their questions to the moment, cites the exact phrase, and replies — with the timestamp linking back so anyone can verify.
Drop in the talk slides, the supporting docs, the changelog, the API reference. Factual questions get matched to the source page and answered with a direct citation — not a paraphrase, not a hallucination.
"v3.2 deprecates the legacy /events endpoint. Migration guide at docs/migration."
Once a question is answered — by the speaker, by ReactLive, by the moderator — the answer is reusable. Variants get the same answer, instantly, for as long as the conference runs.
Match confidence above your threshold? Answered. Below? Held for the moderator.
Before they're answered, they're clustered
Every question that comes in is grouped with semantically similar ones, voted on by attendees, and ranked by heat. Your moderator sees twenty topics, not eight hundred lines. Strategic ones go to the speaker; repeats and factual ones go to the Loop; out-of-scope ones get logged with an owner.

The moderator is always in the loop. ReactLive drafts; the moderator decides what ships, what holds, what goes to the speaker. You're never auto-piloting.
Five things, one surface
Q&A, polls, comments, announcements, and hallway chat — under one QR code. Each one is doing AI work in the background: clustering, sourcing, sentiment-tracking, drafting. Your moderator runs five threads at once, with a co-pilot.
Eight hundred questions cluster into twenty themes. Repeats get auto-answered from the speaker's words. The moderator sees the priority list, not the inbox.
API rate limits
The Loop spots a moment in the talk worth polling and drafts the question. The moderator approves with one tap. Live bar chart on the projector. Multiple choice, word cloud, rating, ranked.
Track changes, room moves, sponsor giveaways. The AI listens to the organiser's mic and drafts the announcement; one tap and it pins to the top of every attendee's chat. No app permissions required.
📣 ANNOUNCEMENT · 09:42
Keynote moved to Hall B. Starts in 10 min.
Light reactions and short comments roll up into a live sentiment read — by speaker, by topic, by minute. Speakers leave with a temperature graph, not just a Q&A log.
Audience-to-audience threads. The AI suggests topic rooms based on who's in the audience and what's being discussed — so attendees find each other around what they care about, not LinkedIn URLs.

Five agents, one event
Five specialised AI agents work the conference end-to-end — before, during, and after. They ingest your speaker pack, set guardrails, run the queue, draft the answers, and write the report. The organiser oversees; the agents do the labour.
Ingests speaker decks, agenda, sponsor briefs, prior-year Q&A. Builds the context graph the rest of the team works from.
Guardrails the room. Filters spam, slurs, off-topic noise. Flags off-limits topics for moderator review. Audit log of every action.
Clusters questions into themes, ranks by vote and heat, suggests polls and announcements when the conversation calls for them.
Runs the Auto-Answer Loop. Drafts cited replies from the live transcript, the speaker pack, or prior answers. Moderator approves; reply ships.
Five-minute exec summary in your inbox. Themes, sentiment, top questions, sponsor performance, NPS. The deck for next year, prefilled.
The agent stack
Each agent has a SOUL.md file — its tone, vocabulary, escalation rules, and red lines. Version it in git. Share across events. Edit as your voice evolves. The agents read this on every interaction so they sound like you, not like a default chatbot.
One conference, one chat
With whole-event mode, attendees scan once and stay in the same chat from keynote to closing reception. Sessions thread inside it. Hallway conversations carry over. The morning's good question is still findable at lunch.

Built for organisers
Multi-track events, sponsor branding, moderation roles, schedule integration, GDPR, exports for the post-event report. The unsexy infrastructure your attendees never see, built by people who've run conferences before.
Sessions running in parallel each get their own scoped Q&A and polls, all inside the same event chat.
Per-session moderators, organiser admins, sponsor-only posters. Everyone sees what they need; nothing they shouldn't.
Header logos, sponsored polls with attribution, branded announcement panels. Sponsors get visibility without buying their own app.
The agenda lives inside the chat. Tap a session, jump straight into its Q&A. Tap "join" to follow live.
Live transcript and Q&A translation across 16 languages. International audiences participate in the language they think in.
Live dashboard during the event. CSV export after. Real numbers for the post-event report and next year's sponsor deck.
Optimised for venue Wi-Fi reality. Offline queueing, automatic reconnect, low-bandwidth mode. The chat stays up when the conference Wi-Fi melts.
No-account model means no email harvesting unless attendees opt in. Anonymous by default; data residency configurable.
No account, by design
The download wall isn't just bad UX — it's a privacy ask attendees never agreed to. ReactLive doesn't need an account to work. Anonymous by default. Identifiable only when an attendee chooses.
Attendees don't make an account. They get a session ID. Nothing about them is collected unless they choose to share a name in hallway chat.
EU and US regions on day one. Attendee data stays in the region of your event, not yours.
Auto-filter for slurs and spam. Per-session moderator roles. One-tap remove on any message. Audit log of every action.
Post-event CSV with engagement stats, top questions, poll results, NPS. Attendee-anonymous unless they opted in to a contact share.
Pricing
Most engagement tools price by attendee, which means you pay more the more successful your event is. We charge per event. You scale; the bill doesn't.
Pre-launch · finalising tiers
We're locking pricing in with our beta cohort. Waitlist members get final pricing first, plus founder support during onboarding.
Honest comparison
Slido is a good Q&A tool. It's been the default for a decade. But the category has moved — attendees expect more, organisers need more, and AI changes what's possible. Here's an honest, row-by-row look at where ReactLive does the same job differently, and where it does jobs Slido doesn't do at all.
