What Creators Are Saying

Results that speak
for themselves.

Honestly I was skeptical. But I ran my worst-performing video through it and it nailed every single reason why it failed. Hook too slow, background music too loud, no clear CTA. Those were exactly the notes I had gotten in comments.

Used the Hook Writer after my analysis and got 5 hooks I actually wanted to use. Usually I spend 30 minutes trying to write a good opening. Now I pick the best one in under 5 minutes.

The retention curve prediction is scary accurate. I analyzed a Reel before posting, saw the predicted drop at second 11, re-edited that section, and the real retention curve after publishing was almost identical to what Retensis showed. The drop was gone.
