1. Concepts with reasoning
Enter your video topic and get two distinct psychological angles — curiosity and transformation — each explained so you understand why it should work before you render anything.
AI YouTube thumbnail generator with real creative strategy.
Most generators hand you an image. GoThumbnails hands you a reason — the angle, the visual strategy, the title that pairs with it, and then the render.
Generate your first thumbnail2. Render at YouTube spec
Every render is a 1280×720 16:9 image with mobile-first legibility: strong focal subject, high contrast, minimal on-thumbnail text and clean negative space for the duration badge.
3. Variations to test
Produce labelled A/B/C/D variations where each version changes exactly one deliberate thing, so your test results actually tell you something.
Questions
Does it copy other creators' thumbnails?
No. GoThumbnails produces original creative direction. It studies patterns in a niche — composition, colour, emotion, text length — and generates fresh concepts instead of reproducing any specific creator's work.
What size are the thumbnails?
1280×720 (16:9), the YouTube recommended size, in both standard and HQ render quality.
Can I edit the result?
You can re-render with an edited prompt, adjust the concept angle, or generate variation batches from any render you like.
How many credits does a thumbnail cost?
A set of two concepts costs 3 credits, and rendering one thumbnail costs 8. New accounts start with 30 free credits.
