For Creators who want a quick, custom thumbnail without a design tool.

Generate an AI thumbnail

Create a cover image for your Space from a text prompt, with an optional reference image.

Overview

Don't have a cover image ready? You can generate one with AI from a short text description, and optionally guide it with a reference image. The result becomes your Space's thumbnail just like an uploaded image.

When to use

  • You need a polished cover quickly and don't have a designed image.
  • You want to try a few visual directions before committing.
  • You have a reference look in mind and want the result to echo it.

The AI thumbnail generator may be unavailable if it has been turned off platform-wide. When that happens, the Generate with AI button is disabled — just upload an image instead.

Where to find it

The generator is available wherever you set a thumbnail: the upload step when creating a Space, and Edit details later. Look for the Generate with AI button next to the thumbnail area.

Generate an image

  1. 1Select Generate with AI to open the generator.
  2. 2Type a prompt describing the image you want — subject, mood, style, and colors all help.
  3. 3Optionally add a reference image to steer the result toward a particular look.
  4. 4Generate, then review the result.
  5. 5If it's not quite right, adjust the prompt and regenerate.
  6. 6When you're happy, apply it — it becomes your Space's thumbnail.
AI Thumbnail Generator dialog with template chips (LED Media Art, Neon Gallery, Immersive Exhibition, Minimal Gallery, Futuristic Space), a prompt field, a reference-image dropzone, and a Generate button.
The AI Thumbnail Generator: pick a template or describe the scene, optionally add a reference image, then Generate.

Daily limit

To keep things fair, each account has a daily limit on AI image generations (20 per day by default). When you reach it, generation pauses until the limit resets — you can still upload your own image any time.

Notes

  • A generated thumbnail behaves exactly like an uploaded one — you can replace it later via Edit details.
  • Clear, specific prompts (subject, lighting, style) tend to give the best results.
