In their own words
Thumbnail X
Thumbnail X is a web service that creates YouTube thumbnails from text prompts. It produces several options to choose from and download, while automatically handling YouTube aspect ratios, selecting AI models, and applying YouTube-specific optimizations. Files are generated at 1280x720 pixels in JPG or PNG format; the FAQ says most results arrive in under 10 seconds. Prompts and images are saved in generation history for later viewing. The Free plan costs nothing and includes five generations, full-resolution downloads, and basic AI models. Plus costs $1.99 a month with unlimited generations, premium models, and priority support. Lifetime access costs 49.99 USD as a one-time payment. Generated images may be used, modified, and distributed commercially without attribution. Google sign-in is available, and the free tier needs no credit card. The API is still in development.
