The AI audience engagement lead for live broadcasts.
The second screen, finally built for the moment. While your audience watches the match, the address, the keynote, the show — you host the room. Live takes, AI-cued polls, shareable clips of every reaction. ReactLive runs alongside the broadcast they were going to watch anyway.
The second-screen mess
Your audience is watching the match. They've got Twitter open for hot takes, Discord for the group chat, group texts on their phone, your Substack tab open in the background, the broadcast in the foreground. The audience you've built is having the moment together — just not with you. The platform you actually own — your audience — is fragmented across five surfaces you don't.
You posted three sharp observations during the second half. They're buried under twelve thousand other tweets by full-time. Your followers saw two of them. The algorithm made the calls.
The community talks great in your Discord, but only the regulars are there. The seven hundred subscribers who paid you to read your Substack don't know it exists. The conversation is small because the surface doesn't pull.
Your closest five friends are the best audience for your live commentary. They're in a group chat. The other six thousand five hundred people who'd love your takes have no way in.
The match ends. Your takes evaporate. Your reactions don't become content. Three hours of your best live thinking and the only artifact is a tired post-match Substack on Tuesday.
The watch room
ReactLive gives every event its own room. Your audience scans the link, lands in the room, and watches the broadcast on their first screen while the room runs on their second. You drop takes, fire polls, react in real time. Everyone in the room reacts together — synced timestamps, shared moments. The watch room becomes the living room you used to share.

That second yellow's harsh. He's playing the ball there, not the man.
Engagement spiked at 73:14 — half the room reacted to the red card. Fire a poll while it's hot?
Reaction stream · last 60s
Your audience opens the link, lands in the room. Browser, phone, anywhere. They watch the broadcast on the screen they were using anyway, with the room on their second. No download, no friend-of-friend invite trail.
Your job is the takes, not the moderation. ReactLive's agents handle the heckle filter, the bot detection, the spam patrol. You watch the match. The room runs itself.
Reactions are timestamped to the broadcast. When you fire a poll at 73:14, everyone in the room knows what 73:14 was. The shared moment becomes a shared artifact, replayable forever.
Three flavours of watch party
A football match isn't a State of the Union isn't an Apple keynote. ReactLive's the same engine; the rooms feel like the host. Sports rooms are loud and reactive. Political rooms are sharp and source-cited. Tech rooms are nerd-deep with running specs. Your tone, your voice, your room.
Football, NBA, F1, UFC, boxing. Pre-match predictions, live takes between actions, post-match heat. The vibe is loud, opinionated, fast — your audience is high on adrenaline, you're feeding the moment.

The Auto-Answer Loop
Two minutes into the match someone asks "what's the score?". By half-time, sixty more people have asked the same. ReactLive transcribes the broadcast, knows what's happening on screen, and resolves the repeats automatically — so you stay focused on the takes that actually need a host.
ReactLive transcribes the live broadcast feed in real time. Score, time, key events, named players, named topics. When the audience asks "did Haaland score?", the answer comes from the actual broadcast — cited and timestamped.
Plug in your back catalogue — Substack posts, podcast episodes, prior watch parties. When someone new asks a question you've answered before, they get your previous take — cited and linked, not regurgitated.

Substack · 14 Mar · cited
The AI watches the room as carefully as you watch the match. When engagement spikes — a goal, a foul, a controversial line — it suggests a poll, a clip, a take. You decide whether to fire. The AI is the producer; you're still the host.
CUE
Engagement spiked at 73:14 — fire a "was that a red?" poll?
After the broadcast
The match ends; the content begins. Every reaction moment — your hot take, the poll spike, the room's roar — is auto-cut into a shareable clip. Branded as your show. Captioned. Vertical or horizontal. Your post-match content is already cut by the time you close the laptop.
Note: clips are of your commentary and audience reaction — not of the broadcast itself, which stays with the rights holder.
Every host take becomes a vertical clip — your face cam, captioned with your line, branded with your show identity. Drop into TikTok, Instagram, Twitter while the broadcast is still running.

The plumbing
A single match is one room. A football season is forty. A campaign cycle is dozens of debates. ReactLive is built for shows that recur — same audience, different broadcasts, persistent identity.
Schedule a season. Subscribers get auto-notified when the next room opens. Persistent room identity across forty matches.
Lock the room to paying subscribers. Patreon, Substack, your own membership system. Public visitors see the post-match recap.
Sponsored polls. Half-time announcements. Branded reaction packs. Sponsors get measurable engagement, you keep editorial.
SOUL.md encodes your show's rules. Heckle filter, slur block, brigade detection. The room polices itself the way you would.
Run a panel show? Bring two or three co-hosts into the same room. Each has their own face cam, their own reaction stream.
The audience reacts in any of 16 languages. Captions auto-translate. Your global audience joins the same room.
Drop the room into your Substack, your Ghost site, your YouTube live page, your fan club. Your domain, your identity.
Who showed up. What spiked. Where they reacted. The dashboard your sponsor pitch needs, plus the data your editorial wants.
