Does it generate the thumbnail image?

No. It generates thumbnail concepts, on-image text, layout notes, and image-generation prompts you can use in tools such as ChatGPT image generation, Midjourney, Ideogram, or Canva.

What should I paste into the tool?

Paste the video title or idea, target viewer, promise, hook, visual proof you actually have, and anything to avoid. Real screenshots, product shots, charts, or before/after details make the output better.

Will it invent fake proof or metrics?

No. The prompt is designed to avoid fake UI, fake charts, invented numbers, and misleading thumbnail claims. If you want a number or benchmark in the thumbnail, include the real number in your input.
