Is the AI thumbnail generator free?

Yes — 100% free, no signup, no usage limits.

Does it save my data?

No. Inputs are processed in your browser and never uploaded to a server.

Can I use it on mobile?

Yes. The interface is fully responsive and works on iOS and Android.

Why does the title text look wrong?

Diffusion models still struggle with crisp, legible text. Use the AI image as your base and add the actual title in Canva or Photoshop afterward.
