Start with your video
Describe the hook and what viewers should notice. Get several thumbnail ideas for one upload.
Make distinct options before you run a test. VisualKit makes the thumbnails; YouTube Studio runs the test.
When you have the idea, use AI thumbnail maker to make a few options and pick the one that reads on a phone.
Use VisualKit to make candidates. Use YouTube Studio to run Test & Compare and read the result.
Describe the hook and what viewers should notice. Get several thumbnail ideas for one upload.
Try a face-led reaction, a product close-up, or a clear result. Small color changes may say the same thing.

One instruction. A more deliberate thumbnail.
Download your thumbnail and add it to your YouTube video.
Give each candidate a different hook. Changing only the color may leave you with several versions of the same idea.




Your thumbnail gets one chance to earn the click before the video starts.
If the thumbnail looks confusing, they click another video.
Each round of feedback can cost another day.
Make a few thumbnails, then pick your favorite.
Real thumbnails created with VisualKit.
Short walkthroughs from our channel on making thumbnails people click.
Getting AI thumbnails past the fake look.
VisualKit helps with the thumbnail options. YouTube Studio handles the test and its result. For your next A/B test, compare thumbnail options with an AI thumbnail maker.
Compare a reaction, a product close-up, or a visible result. Each option should give viewers a different reason to watch.
Add two or three candidates with meaningful differences. A face-led reaction, product close-up, and visible result teach you more than three color grades.
Review the title and thumbnail together, then keep other changes out of the test so the comparison stays useful.
A stronger hook still needs to match the video. Check names, numbers, and claims before you publish.
YouTube says a result can take a few days or up to two weeks. Early leaders can change as more impressions arrive.
VisualKit makes and edits thumbnails. YouTube runs Test & Compare and reports watch-time share, not raw clicks alone.
If YouTube finds similar performance, choose the option that best fits the video and try more distinct concepts next time.

VisualKit helps you make and revise thumbnail candidates. You run Test & Compare in YouTube Studio, where YouTube evaluates the options by watch-time share rather than clicks alone.
Make two or three genuinely different 16:9 options. Keep the title steady, run the test in YouTube Studio, and let the result collect enough data before you choose.
