YouTube Thumbnail Prompt Generator
Three click-worthy thumbnail ideas for your video — ready to paste into ChatGPT or Gemini.
Get my thumbnail promptsA great video still needs the click, and the click comes from the thumbnail. Writing a good image prompt is a skill of its own — this generator writes it for you, based on your video’s title and keywords.
Four questions
Size (16:9 for videos, 9:16 for Shorts covers, 1:1 or 4:5), who is on it (your photo, an AI model or no face), whether you want text and in which language, and a style from bold to clean to 3D cartoon.
Rules that win clicks, built in
One clear focal point that reads on a small phone, strong contrast, a big face or object, two to four words of text — and never in the bottom-right corner, where YouTube shows the video length.
How to use it
- Open your video and go to the SEO step.
- Answer the four questions.
- Copy the prompt for ChatGPT or Gemini and generate the image.
- Rename the file to the suggested name and upload it in YouTube Studio.
Questions creators ask

Can the text be in Hindi?
Yes. Pick the language for the thumbnail text.
How many ideas do I get?
Three different ideas, each with its own prompt for ChatGPT and for Gemini, plus three short text options.
