How to Make an AI YouTube Thumbnail (From Your Own Photo)
The reaction-face thumbnails that top creators use aren't built in Photoshop from scratch anymore — they're a real photo of the creator, dropped into a dramatic AI-generated scene. Here's how to do the same with just a selfie and a title.
Steps
- Upload a reference photo at Stelluna's AI Thumbnail Generator — a clear photo with your face visible, up to 10MB.
- Pick a cinematic style. Tech Studio, Cinematic Dark, Neon Cyberpunk, or Minimal Studio.
- Pick a pose and expression. Each style has its own set of pose options to match the mood of your video.
- Write your thumbnail title. The text the AI will render directly into the scene.
- Generate and download. A 16:9 thumbnail with your face preserved, ready to upload.

Open AI Thumbnail GeneratorWill it actually still look like me?
The prompt sent to the AI model specifically instructs it to preserve your facial identity as the single most important constraint — that instruction is repeated at both the start and end of the prompt, since models can otherwise drift on longer generations. It's not a pixel-perfect copy (it's still an AI generation, not a photo edit), but it's built to keep you recognizable, not to replace your face with a generic one.
FAQ
Is it free?
You get a few free generations per day; create a free account for unlimited use.
Is my photo stored?
No — your reference photo is only used for that one generation and is deleted from the server immediately after.
Can I use a photo of someone else?
Only if you have their explicit rights to it. Generating from a public figure's photo isn't allowed.
How long does a generation take?
Usually 10-20 seconds.
Can I pick the exact same pose across multiple thumbnails for a consistent channel look?
Yes — each style's pose options are fixed and reusable, so you can pick the same one every time for a consistent series look.
