Do I need an account to use this tool?

No. You can use GPTAI.host tools without signing up or logging in.

How do I get better-looking images/designs?

Specify the subject, style (e.g. minimal, cinematic), lighting, composition, and what to avoid. If text looks messy, keep designs text-light and add text later in an editor.

Is it safe to paste sensitive content?

Avoid submitting passwords, private keys, or confidential personal/business data. Your input must be processed to generate an output and may pass through third-party AI services.

Can I use the output commercially?

Usually yes, but it depends on your use case and the underlying AI/provider terms. If you need legal certainty (logos, trademarks, medical/legal), review the output carefully and consult a professional.
