AI YouTube Thumbnail Generator
Thumbnails decide whether your video gets clicked. YTDiscovery's Thumbnail Studio uses Gemini-powered image generation to design pro-grade thumbnails in seconds — no Photoshop, no stock-art hunting.
The problem
Hiring a thumbnail designer costs $20–$100 per video. Generic AI generators produce blurry, low-CTR results that don't match your channel's style.
How YTDiscovery solves it
Thumbnail Studio lets you upload reference images, describe the concept, refine the output, and upscale to 4K — all inside one workflow tied to your video's title and hook.
