We help you know before you post.
firstreactions is a video reactions app for creators. Upload what you made, pick who reacts, watch them react on camera in under an hour.
Why we built it
Every creator faces the same terrifying gap: you finish something, you post it, and only then do you find out what strangers actually think. Friends are too polite. AI is too vague. We wanted honest reactions from the exact people you’re trying to reach — before you press publish.
Real people. Not bots.
Every reaction on firstreactions is a real human, filming on their phone, saying what they actually feel. No generated summaries. No fake enthusiasm. Just the face, the voice, the pause when they don’t get it, the moment they smile.
Made in London.
We’re a small team in London building for creators everywhere. If you use the app and something feels off, tell us — hello@firstreactions.app lands in a real inbox that a real person reads.
