StopScroll

StopScroll is an AI thumbnail generator for YouTube creators and content teams. Instead of producing a single image from a blank prompt, it creates several thumbnail concepts for the same video so the creator can compare visual directions and choose a cover before publishing. The site names faceless channels and niches such as finance, documentary, education, commentary, history and true crime as good fits.

There are two ways to start. With a public YouTube URL, StopScroll reads the video's metadata, description, chapters and transcript signals, then turns that analysis into distinct thumbnail directions. With the title or prompt option, the user enters thumbnail text, an optional prompt and optional subject images. In both cases the user picks styles and an aspect ratio, generates, reviews the results and downloads one.

Up to four styles can be selected per run, such as AI Viral, podcast hosts, product review or cinematic, and each style produces one image. Aspect ratios include 16:9, 1:1, 4:5 and 9:16. Images are made with the gpt-image2 model. Free helper tools download public YouTube and Shorts thumbnails, check for 4K versions, resize images to 16:9 and compress files.

Pricing uses credit packs rather than subscriptions, and one credit equals one thumbnail generation. The Starter pack costs $9 for 40 credits and the Creator pack costs $29 for 140 credits; credits never expire and generation history is saved to the account. Signing in gives one free credit. Thumbnails cannot be edited inside StopScroll, and the service makes no promise about click-through performance.
