Thumbnail X
Hey HN! Software engineer here. As an amateur youtuber, I've been struggling with thumbnails, especially since I don't have any design or editing skills. Decided to give it a try and make my own automatic thumbnail generator. Me being an ADHD person, made sure that there's no parameter tuning and shape choosing and fuss like that, just simply give prompt and generate thumbnail. Increased my CTR from 1.2% to 2.3% (faceless fantasy books niche on youtube) Thumbnail X (completely free for now) - https://thumbnailx.com/ Just wanna add that this is by no means a perfect thumbnail…
