About Thumblore
Thumblore turns a video title into two scroll-stopping YouTube thumbnails in about 5 seconds — no design skills, no Photoshop. Its AI is trained on patterns pulled from millions of high-performing thumbnails, so it automatically handles composition, bold readable text, color contrast, and the facial expression most likely to earn a click. Upload a photo or generate an AI avatar once, then reuse your face across every thumbnail you create. Generate multiple variants to A/B test, and export at YouTube's exact required resolution every time. Creators switching to Thumblore report an average 83% lift in click-through rate. Built for YouTube and Shorts creators who want more views without becoming a graphic designer.
