Account and avatar menu

The sidebar avatar is the main account action entry. It opens account settings, appearance and language controls, legal links, help, and sign out.

• The top profile block shows your display name and email. Click it to open account settings.
• Settings control light, dark, system theme, and language.
• The legal area contains terms, privacy, DMCA, refund, contact, and this manual.

Generation workflow

Generation follows submit, hold credits, execute, then complete or refund. Users mainly control prompt, model, aspect ratio, resolution, any available quality tier, and count.

• Free users can use the free model; member models, batch generation, and high resolutions depend on the current plan.
• Credits are held when a job is submitted and returned automatically if execution fails.
• Generated images are saved to My works for review, download, or publishing.

Credits and membership

Credits pay for generation costs. The credits button beside the avatar shows balance, plan, renewal or expiry date, and top-up access.

• When balance is insufficient, the generate button blocks submission and shows the required credits.
• Membership benefits follow the active plan shown in the billing dialog and account page.
• After cancellation, access usually remains active until the paid period ends.

Works and favorites

My works, Favorites, and the public gallery are separate areas. Personal generations stay in My works, favorites save public works, and publishing requires review.

• My works stores your personal generation results.
• Favorites shows public works you saved.
• Published works enter a review queue before appearing in the public gallery.

Support and troubleshooting

For generation, billing, sign-in, or copyright issues that cannot be solved locally, use Contact from the avatar menu.

• If the page looks stale, refresh and confirm you are still signed in.
• If generation takes too long, check My works first, then retry later.
• For billing, refund, copyright, or account issues, email support with account email, time, and screenshots.

  "model": "gpt-image2",
  "aspectRatio": "1:1",
  "resolution": "2K",
  "quality": "auto",
