Analyzing your thumbnail... Checking CTR potential
ThumbAura - Free AI YouTube Thumbnail Analyzer
Your thumbnail is the single most important factor in whether someone clicks your video or scrolls past it. Studies show that 90% of top-performing YouTube videos have custom thumbnails. Yet most creators design them by gut feeling with no objective feedback on what is working and what is not.
ThumbAura is a free AI thumbnail analyzer that gives you instant, professional feedback on your YouTube thumbnails. Upload any thumbnail and get a detailed score out of 10, CTR potential rating, text readability analysis, emotion impact score, color contrast evaluation, and specific improvement actions powered by Google Gemini AI.
The Compare mode lets you upload two thumbnail versions side by side and get a clear winner with detailed reasoning, perfect for A/B testing before you publish. The Single mode gives you a deep dive analysis with font suggestions, color recommendations, and copy-paste search queries for design platforms.
