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 maker for huge YouTube moguls with millions of subscribers but I'm sure it's gonna be extremely helpful for beginner youtubers and medium size channels struggling with thumbnails.
Tools used: 1. Cursor for development (shoutout to claude oppus 4.0) 2. Few image generators (primarily ideogram, but leonardo ai, deep ai and gpt 4o as fallbacks) 3. Few llms (chatgpt, claude, gemini for validating images and prompt enhancement) 4. AWS and Redis for storage & caching 5. Digital ocean for hosting and db 6. Python

I did the experiment for my fantasy youtube channel (https://www.youtube.com/@AIBookBytes) and CTR increased from 1.2% to 2% which for me was a huge deal.
This is probably not the tool for super high subscriber youtube channels but from amateurs to mid size youtube channels could be very helpful. Obviousy it is clear that it's AI generated by many channels use that and still are successful. As long as expressions are clear and text is bold and visible, should be good.
