A creator taps a trailer, reacts on camera or voice only, and walks away with a clip built for their own channel. Studios and sponsors see exactly how the trailer landed. Everyone knows the recording is on. That is the whole point.
A Reactor opens a trailer on Reactr, agrees on a clear consent screen to be recorded, and hits start. The trailer plays while the reaction records. No app, no editing software, no upload wrangling.
The finished clip belongs to the creator, edited and sized for their own channels. That is why Reactors show up: the trailer drop is a moment worth capturing, and Reactr captures it well.
Reactr's server-side editor turns a full reaction session into finished content in under a minute. It listens for the moments that matter: laughs, gasps, exclamations, and every Pause & Comment segment a fan records.
Every clip is simultaneously two things: content the fan wants to post, and evidence of exactly how the trailer landed. That double life is what makes Reactr different from a research tool or an editing app.
Reacters choose a trailer because they want to react to it. Before any recording starts, a plain-language consent screen states what is recorded, what it is used for, and how long raw footage is kept. Recording begins only after an explicit, separate agreement, never bundled into terms of service.
For studio and exhibitor partners, this is a feature, not a constraint: a campaign your legal team can approve quickly is a campaign that actually ships.
Every campaign comes with a dashboard built on signals that require no biometrics and no guesswork, because they come from what fans actually did.
The insight layer is aggregate and honest. We report what fans did, not scores invented about them.
Knowing a camera is on does not fake a gasp. A first watch happens exactly once, and the reaction it produces is involuntary: the jump at the reveal, the laugh at the needle drop, the pause to yell about a cameo. Reaction videos became one of the internet's biggest formats precisely because audiences can tell the real thing when they see it.
Reactr's design leans into that instead of pretending observation away. Fans come to react, so the incentive is honesty: an overacted reaction makes a bad clip, and a bad clip does not get shared or featured. The format polices itself.
What studios get from that is something surveys and panels cannot produce: thousands of real first watches, each one generating both a data point and a piece of earned media that carries the title across social.
Facial-coding vendors and survey panels have measured trailers for years, and the market clearly values that intelligence. Reactr is not a denial of that category. It is a different trade: paid panels produce a report; Reactr produces a report and a wave of fan-made content, from the audience you actually want to reach.
| Method | Who Reacts | What You Get | Becomes Content? |
|---|---|---|---|
| Focus groups | 8 to 20 recruits | Declared opinions | No |
| Panel webcam facial coding | Paid research panel | A report | No |
| Social listening | Whoever posts | Noisy post-hoc signal | Already was |
| Reactr | Real fans who opt in | Moment-by-moment signal + clips | Yes, that's the point |
Panelists are paid to watch; fans choose to. Panel data stays in a PDF; fan reactions travel across TikTok, Reels, and Shorts carrying the title with them. And because campaigns run through studio and exhibitor channels, the audience reacting is the audience being marketed to, not a rented sample.
The question was never whether reaction data matters. It is whether the reaction is real, and whether it works for the campaign after it is measured. Reactr is built to make both answers yes.
The fastest way to understand Reactr is to record a reaction. It takes about as long as the trailer.
