GenLayers
AI YouTube thumbnail generator with live editor, no login required
Visit genlayers.com ↗What is GenLayers?
GenLayers generates YouTube thumbnails optimized for clicks using AI analysis of top-performing videos in your niche. Users enter a video title, and the tool analyzes competitor thumbnails via YouTube's API to identify successful design patterns, then uses AI to create an initial design with pre-configured text and styles ready for editing.
The core feature is a live editor that lets creators customize every element—text, colors, shapes, and layouts—before exporting. Exports are available in YouTube's recommended 1280×720 format as PNG, JPG, or WebP. The service is completely free with no account required. The maker built it using Gemini models and Pollinations.ai to balance AI speed with creator control.
