Thumbnail downloader
Paste any YouTube link and grab the full-size cover. Study it, then remake it on the bench.
Thumbnail sizes
See the three sizes the bench renders: 16:9 for YouTube, 9:16 for Shorts and Reels, 1:1 for square posts. Pick the ratio before you render and the layout is composed for it, not cropped.
Thumbnail tester
Drop a cover into a fake search result and a phone feed. If it does not read at this size, it will not read on YouTube.
Your face in any scene
Upload one selfie to Face Lab. The bench cuts it out, renders up to eight expressions of it, and puts it into any scene you describe. No photoshoot.
