How One UGC Reaction Video Drove 55M Views for an AI Coding App
Before this format took over, @kaisbrf looked like a fairly standard UGC account.
It was testing all sorts of strategies, from “i love gen z” to “i spent [x] hours” hooks, but still stuck at low viewership.

Then on May 25, everything changed.
A single video hit nearly 55M views on Instagram. The hook:
“POV: you gave a chance to the IT guy and he sent this… like wtf“
She opens in selfie mode, headphones on, hand over her mouth in a shocked reaction. Then she flips the camera to her laptop screen, where a website the “IT guy” built is asking her on a date.
She tries to press “no.” The button keeps moving away every time she gets close. Eventually she gives up and hits “yes.” A GIF pops up:
“WAIT YOU ACTUALLY SAID YES??”
Then comes the date planner: pick a day, pick what you want to do.
That’s the whole video. There’s no forced app mention, no CTA slide, no “link in bio” moment. The product is the bit.
Two days later, a second ambassador who had also been stuck in low views replicated the exact same format.
She hit 8.8M views.
Then she did it again. And again. The streak of viral videos with the same structure kept going, and at the time of writing, it still is.

That’s the clearest signal of how transferable this format actually is.
It doesn’t depend on the original creator’s audience size or follower count.
The format along with this specific hook is doing the work.
The same principle recently drove huge numbers for Cantina. They led with a funny app made AI-generated dating video, leaned into the emotional hook, and went extremely viral.
Replit took the same idea and adapted it to their niche. Instead of an AI-generated clip, the centerpiece is a vibe-coded website, but it’s still highly visual.
The dating angle stays. The shocked reaction stays. The “how was this made?” comment section stays.
For apps built on user creation, this might be the cleanest conversion path available: let someone build something funny, let the reactions do the reach, and let the comment section do the selling.
