Hey everyone 👋

I built **ThumbPrompt** to solve a problem I kept facing when generating YouTube thumbnails with AI. Most image models change the face too much, so the thumbnail doesn’t actually look like the creator.

ThumbPrompt helps generate **structured prompts for thumbnails and posters** that work with tools like Midjourney, Flux, ChatGPT, and Nano banana.

The main feature I focused on is a **face-style prompt builder**. It creates prompts designed to preserve the creator’s facial identity, so the generated image stays very close to the original face instead of turning into a different person.

Other things included in the launch:
• Step-by-step prompt builder
• 100+ proven thumbnail prompt examples
• Trending thumbnail styles
• Works with multiple AI image models
• Free to use, no login required

If you create YouTube thumbnails or posters with AI, I’d really appreciate your feedback on what could make it better.

Thanks for checking it out.
