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

Questions & Answers

As answered by people managing Duolingo and ReactLive.

What makes your product unique?

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.

Why should a person choose your product over its competitors?

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:

  • It answers, not just collects โ€” the Auto-Answer Loop resolves most questions live, grounded and cited.
  • In your voice, on your rules โ€” a single config file controls tone and red lines; a human can override anything. It's not a black box.
  • Everyone leaves with the knowledge โ€” automatic summary, answered queue, insights, and searchable transcript sent to the whole audience.
  • Nearly zero friction โ€” under 90 seconds to launch, QR-first for the audience (no app, no account), one-line embed, plus an MCP connector for AI agents.
  • Priced for reality โ€” a genuinely free tier and self-serve, usage-based pricing, not per-seat "contact sales" contracts.

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.

How would you describe the primary audience of your product?

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.

What's the story behind your product?

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 environmentsโ€”including 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.

Duolingo Reviews

  1. A review

    It's incredibly easy to use and the regular reminder from the app about practicing more keep you consistent. Besides,in my opinion,it also can be not only a tool for learning languages,but a good entertainment for kids too. I've been practicing here almost every day throughout the year and i highly recommend Duolingo:))

    ๐Ÿ‘ Pros:    I added everything i want to be mentioned above
    ๐Ÿ‘Ž Cons:    Perhaps the design may look "too childish" for some adults,but it's only the matter of taste
  2. Pretty good

    Duolingo is a quite nice language learning app for the begginers and for those who want to know a certain language on a pretty good medium level(It's like something between A2-B1,i suppose). Moreover, I'd like to admit it's can be useful for kids as well because the app has cute design and playable interactions , challenges and its own little app - shop where you can buy different bonuses for you ,and in my opinion,children could like an idea of learning languages in a playable form. Though, Duolingo can be rather annoying, when you miss one or two days of studying ,so it'd be really awesome if my brother,for example, who uses this app ,could make his own studying schedule here.

  • how gamifying my life helped me build better habits and achieve my goals
    Duolingo: a language-learning app that uses points, levels, and rewards to keep you motivated.

    Hi! I wish I'd seen a post like this a few months ago. I would have been interested then. By now it's a little late for me. I just signed up for the 2 week free trial since that's about all the time I have left before I leave. If you can, use a desktop computer/laptop to do duolingo.com and it will have no ads and unlimited hearts! Not as convenient as the app on a phone but saves tons of time and you can do it...
