ReactLive โ The AI Event Co-Pilot
ReactLive is an AI audience engagement platform for live, in-person, and hybrid events. Think of it as the AI meeting copilot you know for video calls โ but built for the room. Where tools like Read.ai join your Zoom or Teams call, ReactLive runs your town hall, conference, all-hands, classroom, or podcast AMA, turning everything said on stage into instant, cited answers and a summary every attendee walks away with.
At its core is the Auto-Answer Loop. ReactLive captures your speaker and documents as structured, timestamped context, matches each audience question against it in under a second, and drafts a grounded answer โ cited to the source, in your own voice. Questions that clear your confidence threshold are answered automatically; anything ambiguous is queued for a moderator, ranked by relevance, not upvotes. So the quiet majority finally gets answered, repeats resolve instantly, and nobody leaves with a "we'll follow up" that never comes.
ReactLive also runs the room with you: it tracks audience sentiment in real time, drafts polls for one-click approval, and pushes timely announcements. When the event ends, everyone gets a recap โ summary, answered questions, insights, and a searchable transcript.
Setup takes under 90 seconds, no sales call. Your audience joins from any device via QR code or link โ no app, no account. Embed it anywhere with one snippet, or call it from Claude, Cursor, or your agents via the MCP connector.
Key features: - Real-time AI answers cited to your live transcript and documents - Live Q&A with intelligent, relevance-based moderation - Real-time sentiment tracking across questions and polls - AI-drafted polls and announcements with one-click approval - Post-event summary, insights, and searchable transcript for all - Answers in your own voice and rules, from a single config file - QR-first participation โ no app or account for your audience - A free tier with usage-based pricing, no per-seat traps

ReactLive's answer:
ReactLive doesn't just collect questions or transcribe a room โ it answers, in real time, grounded in what was actually said.
The key differentiators:
It owns a venue nobody else does. Meeting copilots (Read.ai, Otter) only work inside video calls โ they go blind the moment you're on a stage or in a room. Q&A tools (Slido, Mentimeter, Pigeonhole) work in the room but are just question-collection boxes. ReactLive is the only one that brings a true AI copilot to live, in-person, and hybrid events.
The Auto-Answer Loop. It captures your live speaker and documents as cited, timestamped context and answers audience questions against it in under a second โ automatically resolving the repeats and the quiet-majority long tail that a human moderator never gets to. Everyone else makes the audience wait on a moderator; ReactLive answers most of them before the moderator even looks.
Answers in your voice, on your rules. A single config file (SOUL.md) defines tone, red lines, and escalation โ so the AI speaks as you, with a human able to override anything. It's grounded and cited, not a black box.
It closes the loop after the event. Every attendee leaves with a summary, the full answered queue, insights, and a searchable transcript โ the knowledge doesn't walk out with the room.
Radically low friction. Under 90 seconds to your first event, QR-first for the audience (no app, no account), one-line embed anywhere, plus an MCP connector so agents like Claude or Cursor can call it โ with a genuinely free tier and usage-based pricing instead of per-seat enterprise contracts.
ReactLive's answer:
ReactLive beats different competitors for different reasons. Here's how we see it:
vs. Slido, Mentimeter, Pigeonhole (the Q&A/polling tools). These collect questions and let a moderator pick a few; everyone else is ignored. ReactLive answers โ automatically, in under a second, cited to what the speaker actually said. Choose ReactLive if you're tired of the quiet 80% never being heard, repeat questions clogging the queue, and a "we'll follow up" that never happens. Same live-event job, but the AI does the heavy lifting instead of a scrambling moderator.
vs. Read.ai, Otter, Fireflies (the meeting copilots). These only work inside a Zoom/Teams/Meet call โ they can't see a stage or a live audience. If your event happens in a room or hybrid, they simply don't work. ReactLive is the only copilot built for the physical and hybrid room. (They're complementary, not competitive: use Read.ai for your calls, ReactLive for your events.)
vs. doing it manually / a human moderator. ReactLive runs four jobs in parallel that no single person can โ answering the long tail, reading sentiment in real time, drafting timely polls, and pushing announcements โ while your team stays in the actual conversation.
The reasons that tip a decision:
One-sentence version: Choose ReactLive because it's the only tool that actually runs your live event with you โ answering your audience in real time from cited context, in your voice โ where Q&A widgets only collect questions and meeting copilots can't see the room at all.
ReactLive's answer:
Event hosts and organizers โ comms and internal-communications teams, event and community managers, conference and webinar producers, educators, and creators/podcasters โ anyone who runs live, in-person, or hybrid events (town halls, all-hands, conferences, AMAs, webinars, classrooms) and wants their audience's questions answered in real time.
ReactLive's answer:
While the platform itself is our newest AI-native release, our team spent years building and powering the audience engagement engines behind some of the world's most demanding live environmentsโincluding all Microsoft High-Priority events (Build, Ignite), CES, and the United Nations. Crucially for a major newsroom, our team also delivered the core live blogging and Q&A infrastructure that The Washington Post still relies on to power their weekly reader threads.
We built ReactLive as the next logical evolution of that work, specifically designed to solve the heavy moderation burden of hybrid media panels:The Auto-Answer Loop: ReactLive tracks your live panel audio in real time, automatically drafting cited answers to repetitive background questions in the chat, filtering out noise so your moderators can focus on prime audience queries. Newsroom-Grade Control (SOUL.md): Guard and enforce the exact editorial standards, tone constraints, and red lines via a version-controlled markdown file that dictates AI behaviour.
Zero Friction for Attendees: No app downloads or account logins. Online stream viewers and physical front-row ticket holders scan a single QR code to enter the interactive space in three seconds.
I often use the Hunter Google Chrome extension to assist me in discovering the contact details of new outreach targets. The only drawback is that I quite often exceed my free monthly allowance of lead requests.

A few things worth flagging: PDL beats Clearbit's historical rates for US and Western European companies, but drops to ~52% match rate for Japan and South Korea specifically. Apollo underperforms on raw company matching but returns significantly more contacts per domain in Prospector-style queries than Clearbit's Prospector ever did โ the tradeoff is more stale titles in the result set. Hunter.io is fast and cheap... - Source: dev.to / 3 months ago
The real conclusion I'd push back on from every vendor comparison I've read: there is no single tool that solves reverse lookup at 80%+ accuracy with clean data. The waterfall is the answer. The question is whether you build it yourself with PDL + Hunter.io + Prospeo, or use a platform like Clay to abstract the plumbing โ and whether you're willing to pay FullEnrich's premium for that abstraction. - Source: dev.to / 3 months ago
Last year I ran the same LinkedIn Sales Navigator export through three enrichment APIs. Apollo matched 61% of the emails. Hunter.io matched 54%. An OSINT-first pipeline I'd built in n8n โ pulling from public sources before hitting any paid API โ matched 79% and cost roughly $0.003 per contact. The delta wasn't magic. It was sequence. - Source: dev.to / 4 months ago
Start with diligent email list hygiene. Remove invalid, dormant, or unengaged addresses regularly. Use free verification tools like NeverBounce or Hunter.io โ many of which offer limited free API calls โ or build your own heuristics. - Source: dev.to / 7 months ago
By putting a mailto link out there, you also share your contact details with any legitimate outreach specialists that wish to reach you. Finding all your company emails hidden in the html code is as easy as a single tap on a hunter.io widget (many similar tools are also available). - Source: dev.to / almost 2 years ago
