Frequently Asked Questions

Is it free?
You get a few free tries per day; create a free account for unlimited use.

Is my photo stored?
No — your uploaded reference photo is only used for the generation itself and is permanently deleted from the server right after.

Does the result actually look like me?
The AI model is specifically instructed to preserve your facial identity — but since it's an AI generation, small variations can happen; it's not a pixel-perfect copy.

Can I only use my own photo?
Yes — you may only upload your own photo or an image you hold the rights to. Generating from someone else's photo, especially a public figure's, isn't allowed.

Can I write the title in any language?
Yes, you can type the title text in any language or script.
