For Creators
The Thumbnail Problem Every Creator Faces
You're not alone. Every creator struggles with the same challenges.
Hours of design work
You spend countless hours designing thumbnails, never knowing which will perform best.
Post and hope
You post your content and hope it works, with no way to test before going live.
Low CTR hurts growth
Low click-through rates mean the algorithm buries your content, limiting your reach.
No way to compare
You never know what would've performed better because you can't test multiple options.
Wasted time and effort
All that design work goes to waste when your thumbnail doesn't resonate with viewers.
Guessing game
Every upload is a gamble, with no data to guide your thumbnail decisions.
