AI Thumbnail Maker
Create viral YouTube thumbnails with AI using your video title, reference image, face, or sketch.
GenLayers is a web-based AI thumbnail studio for YouTubers. Most AI image generators struggle with text, and on a YouTube thumbnail the text is often the whole hook. GenLayers was built around that problem. Type your video title and a rough idea the way you’d normally describe it, and the tool expands it into a structured prompt and generates a 16:9 thumbnail with bold hook text. Creators don’t need to write long, detailed prompts or learn prompt engineering.
There’s no subscription. Credits are bought once and used whenever you want. New users get 200 free credits on signup, and every credit pack includes a commercial usage license. GenLayers is built and maintained by an independent developer.
Features
Title-to-thumbnail generation with no prompt engineering
Clean, readable text on thumbnails, one of the main reasons the project exists
Sketch editor: draw your layout and the AI follows the spatial structure instead of relying only on a text prompt
Reference image or previous thumbnail upload
Add your own face from a quick selfie, with a pipeline designed to keep the face consistent across swaps and edits
Background swapping
Plain-English fine-tune edits for any detail, so small changes don’t mean starting over
Pay-once credit packs with a commercial usage license
Coming next: a layered canvas where text, face and background are separate editable layers, so individual elements can be moved, resized or changed without regenerating the whole thumbnail
