YouTube thumbnails that get the click.
Describe your video — or paste the title — and AI generates a bold, scroll-stopping thumbnail in seconds. Add your face, pick from 100+ styles, let AI write the text. No design skills, no Photoshop.
One prompt. Every part of the thumbnail.
From the idea to the headline to your face in the frame — the AI Thumbnail Maker handles it, and hands you the controls when you want them.
Auto-fill from your topic
Type your video idea and AI writes the full image prompt — then auto-picks the style, subject emotion, negative prompt, and on-image text. Start from a finished brief instead of a blank box.
Enhance my prompt
One click turns a rough line into a detailed, model-ready prompt — sharper subject, lighting, mood and composition.
100+ Style Dictionary
Search a library of creator-tested styles — MrBeast, cinematic, gaming, vlog, horror and more.
Style Blender
Mix a primary and secondary style with a ratio slider for a look that's unmistakably yours.
Put yourself in it
Upload your photo as the subject and AI builds the thumbnail around your face.
AI-written text
Turn text on, type a headline, and pick a style — 3D glowing, neon, metallic gold, cartoon or horror — with auto-contrast so it pops off the image.
Emotion control
Shocked, hyped, curious, crying, angry — direct exactly how your subject reacts to camera.
Style reference
Upload a thumbnail you love and match its look, lighting and energy.
Negative prompt
Exclude clutter, watermarks, extra fingers and blur — clean results, every render.
Every size
16:9 for YouTube, 9:16 for Shorts & Reels, 1:1 for square — all from one idea.
