What YouTubers Are Saying
"Before ThumbGen my CTR was usually around 3–5%. Now most of my videos sit somewhere between 12–15%, which is honestly way better than I expected."
Alex Chen
Tech YouTuber (50K subs)
"I'm not a designer at all, so thumbnails were always stressful for me. This makes it super easy to get something that actually looks good and fits my vibe."
Sarah Miller
Lifestyle Creator
"The reference images are what sold me. I can keep the same style across my channel without overthinking every thumbnail."
