Thumbfa.st

Generate YouTube thumbnails with reusable faces and visual references

Meet Thumbfa.st

Thumbfa.st is an AI thumbnail generator for YouTube creators. Users can start from a prompt, a template, a reference thumbnail, or a rough sketch that indicates the desired layout. Saved person profiles help reuse a recognizable face across new designs, while an inspiration library keeps visual references available for later projects.

The tool can generate several variations together so a creator has alternatives to compare or test. Its editor supports annotated sketches, and a podcast workflow adapts an existing thumbnail template for different guests. Thumbfa.st is designed around recurring thumbnail production, where a channel needs fresh compositions while maintaining familiar people, colors, and visual style.
