What is the Thumbnail Roaster?

Our AI-powered Thumbnail Roaster analyzes your YouTube thumbnail and provides brutally honest feedback on what's working and what's killing your click-through rate. You'll get a score out of 100, detailed breakdowns across 8 key metrics, and actionable fixes to improve.

How does the CTR score work?

Our AI evaluates your thumbnail across 8 critical factors: First Glance Impact, Visual Hierarchy, Subject Effectiveness, Emotional Trigger Strength, Text Clarity, Color & Contrast, Curiosity Gap, and Brand Clickability. Each category is scored 0-100, and we combine them for an overall CTR prediction.

Is the Thumbnail Roaster free?

Yes! Free users get 1 roast per day. Paid subscribers get 5 roasts per day. This gives you enough to analyze your thumbnails and iterate on your designs without limits holding you back.

What image formats are supported?

We support PNG, JPG, and WebP images up to 10MB. You can either upload a file directly or paste a URL to any publicly accessible image. For best results, use your actual YouTube thumbnail dimensions (1280×720).

How accurate are the CTR predictions?

Our AI is trained on thousands of high-performing YouTube thumbnails across various niches. While no prediction is 100% accurate (audience, title, and timing also matter), our scores correlate strongly with real-world CTR performance. Use it as a guide to improve, not as an absolute guarantee.

Can I use this for thumbnails from other platforms?

Absolutely! While optimized for YouTube, the principles of good thumbnail design apply everywhere. Use it for Twitch stream previews, podcast covers, blog featured images, or any visual that needs to grab attention and drive clicks.

What should I do with my roast results?

Focus on the 'Immediate Fixes' section first—these are quick wins that can boost your CTR. Pay attention to the 'CTR Killers' to understand what's hurting you most. If you get a low score, don't despair—use our AI Thumbnail Generator to create an improved version based on the feedback.

How often should I roast my thumbnails?

We recommend roasting every thumbnail before publishing, especially for important videos. Also roast your top-performing thumbnails to understand what makes them work, and your underperformers to identify patterns to avoid.
