Simulate how your thumbnail looks to color-blind viewers with protanopia, deuteranopia, tritanopia, and grayscale — all shown side by side.
Preview how your thumbnail looks at real phone sizes — small feed cards, search results, and suggested-video corners — over a simulated mobile feed.
Compare a before and after thumbnail side by side with a draggable slider, plus a swap view and full-size comparison, to judge which design reads stronger.
