How it scores your thumbnail
Color Vibrancy
Checks saturation levels — gaming thumbnails need rich, punchy colors to stand out in the feed.
Contrast
Measures light/dark range. Strong contrast means the thumbnail reads instantly on any device.
Face/Reaction
Detects skin-tone pixels as a proxy for face presence — a proven CTR amplifier in gaming.
Composition
Edge density analysis spots over-cluttered or under-designed thumbnails.
Rule of Thirds
Checks if the focal point sits at a thirds intersection for dynamic, click-inviting framing.
