Thumblore

Thumblore is an AI-powered thumbnail generator built for YouTube and Shorts creators. Drop in your video title and it produces two polished, click-optimized thumbnails in roughly 5 seconds — no editing software, no design background required. The AI draws on patterns from millions of top-performing thumbnails to choose the layout, headline text, color contrast, and facial expression that drive the most clicks. You can save a personal avatar (upload a photo or generate one with AI) and reuse it.
