サムネAI

📖 What is サムネAI?

A tool that generates stream and video thumbnails in seconds just by typing in some text for the AI. It supports 16 templates covering VTuber, game streaming, and more, and you can keep refining the result afterward just by telling the AI what to change. The free plan includes up to 3 credits.

💡 When to Use It

Use it when you don't have time to design a thumbnail, or want a professional-looking result even without design skills. Since the free plan lets you try a few thumbnails right away, it's also an easy option to practice with if you're making a thumbnail for the first time.
