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
Lensmor is a next-generation AI-native Event Intelligence and GTM (Go-To-Market) Signal platform tailored for B2B enterprises. Unlike traditional providers that simply sell static attendee lists, Lensmor solves the critical challenge of converting "Who is there" into "Who is ready to buy." By aggregating data from over 160,000 top global B2B events, Lensmor powers a three-tiered intelligence engine: Event Aggregation, Dynamic Lead Graphs, and Deep Intent Analysis, equipping sales teams with actionable intelligence that goes far beyond static spreadsheets.

LensmorReactLive'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.
Lensmor's answer:
Lensmor is the only AI-Agent-native platform in the pre-show exhibitor intelligence space. While competitors like Vendelux sell static attendee databases, Lensmor lets sales reps describe their ICP in plain language and instantly get a qualified prospect list โ enriched with verified contacts and AI-drafted outreach โ weeks before the event. The entire workflow from discovery to first message takes minutes, not days.
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.
Lensmor's answer:
Vendelux, the category leader, is a traditional database product built around human sales cycles. Lensmor is Agent-first and self-serve: no onboarding calls, no static exports. B2B teams in tech, finance, and consumer industries can run a full pre-show prospecting workflow โ find exhibitors, enrich contacts, draft outreach โ without waiting on a vendor. For teams that want speed over depth of enterprise features, Lensmor wins on time-to-pipeline.
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.
Lensmor's answer:
B2B marketing and sales teams (Manager level and above) at tech, finance, and consumer companies that actively exhibit at trade shows. They spend significant budget on event participation and want to convert that spend into measurable pipeline โ not just badge scans.
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.
Lensmor's answer:
The founding team observed that the pre-show exhibitor intelligence market is massively underpenetrated โ Vendelux is the only real player, and it operates on a traditional data-sales model. With AI Agent technology maturing in 2025, building a self-serve, AI-first version of this workflow became viable for the first time. Lensmor was built to give any B2B team the same pre-show intelligence advantage that was previously only accessible to large enterprise sales orgs.
Lensmor's answer:
Large language models (Claude by Anthropic) for the AI Agent layer, large-scale web crawling and data aggregation covering 160,000+ global B2B events, contact enrichment APIs, and a REST API backend supporting CRM integrations with HubSpot and Salesforce.
Lensmor looks especially promising for teams working around exhibitions and trade shows. It feels focused, practical,and much more relevant than generic market monitoring tools. I like that it seems built to help users quickly spot useful industry and competitor signals without getting lost in noise.
