Overview

Product summary

Review the store description, core capabilities, and common use cases.

YouTubers want to preview their new upcomming video on amongst the other one on the YouTube Homepage to see if their thumbnail is good or bad. They often screenshot the homepage, go in Photoshop and make the job themself. This extension just requires you to upload your thumbnail and type the title of your video and you're done!

You also have pretty interesting options such as:

* Placing your thumbnail randomly on the homepage so you have to try to find it yourself and see if it's efficient or not.

* Dark mode

* Does not requires you to login and give your credential

* Remembering your last submission
