The Ultimate Thumbnail Lab

Every metric that moves clicks — measured, scored, and explained.

AI Generation

Generate professional thumbnails from a text prompt using Flux AI, optimized for your specific niche and channel style.

Face & Emotion Detection

Our face detection model locates every face and scores expression, size, and engagement potential.

Contrast & Saliency

Ensure your thumbnail pops in a crowded feed with optimal contrast, color vibrancy, and visual hierarchy scores.

Text Legibility

Our text extraction engine reads your text and grades it at real mobile resolution — the size most viewers actually see on a phone.

Niche Benchmarking

Compare your scores against the gold standard for Gaming, Finance, Tech, Cooking, Fitness, and 9 more niches.

Actionable Recommendations

Every score comes with specific fixes — not vague advice. Raise contrast, resize your face, sharpen your text, and re-analyze in one loop.

From Idea to Click

Three steps to thumbnails that actually perform.

1

Describe or Upload

Generate from a text prompt with Flux AI, or upload a thumbnail you already have. Both paths lead to the same deep analysis.

2

Analyze & Score

Our ML pipeline evaluates face emotion, contrast, text legibility, aesthetic quality, and saliency — then benchmarks every signal against your niche.
