Generate ready-to-paste AI image prompts and overlay text ideas for your next YouTube thumbnail.

AI Powered Thumbnail

AI POWERED

This generates text prompts ready to paste into an image generator (Midjourney, DALL·E, etc.), plus overlay-text and placement guidance — it does not render a finished image for you.

How It Works

Describe Your Video

Enter the video title and a short script/summary, then either pick 2-5 built-in styles or upload reference thumbnails you like.

AI Recommends A Style

An AI strategist picks the best-fitting style for THIS video (or extracts the shared style from your reference images) and suggests overlay text.

Get Ready-To-Paste Prompts

A second pass turns the chosen style into 2-3 detailed image-generation prompts, plus overlay text and placement guidance.

Paste & Generate

Copy a prompt into Midjourney, DALL·E, or any image generator, then add the overlay text yourself in an editor for a crisp, legible result.

Frequently Asked Questions

Does this generate an actual thumbnail image? ▾

No — it generates a detailed text prompt you paste into an image generator (Midjourney, DALL·E, Stable Diffusion, etc.), plus separate overlay-text and placement guidance you add yourself afterward.

Why doesn't the prompt include my overlay text? ▾

AI image generators are still unreliable at rendering exact, legible text. The prompt describes only the visual scene; adding your overlay text as a real typography layer afterward looks far crisper.

What's the difference between the two modes? ▾

"Style Presets" picks the best of 10 built-in thumbnail styles for your video. "Reference Images" instead looks at 2-5 thumbnails you already like and extracts their shared visual style.

Are my uploaded reference images stored? ▾

No — they're used only for that one request to the AI and are never written to disk.
