Rates YouTube thumbnails and suggests better titles and variants
Thumbnail AI scores an uploaded YouTube thumbnail on audience fit, emotional pull, curiosity gap and how clickbait it reads, then lists concrete changes and alternative titles. A generation step produces reworked thumbnail options from the same source image. It is a single-purpose tool from an independent developer, metered by daily analyses rather than a credit wallet.
Free accounts get 10 analyses a day; Pro at $9.99/month raises that to 100 and adds 120 thumbnail generations per month.
Use tool ↗A cheap second opinion before you publish, useful precisely because it is narrow — it does one thing and does not pretend to be a channel suite. Treat the score as a prompt to think, not as a CTR prediction.
Watch out: The product moved off its old thumbnail-ai.ybouane.com subdomain to thumbnail-ai.app, so older catalogue links and bookmarks point at the wrong place.
