Stable Diffusion: AI 3D creator turns an idea or one source image into a usable 3D asset. Create from text in any supported language, or upload a clear image of an object or character. Choose an optional visual style, generation quality, and output profile while seeing the exact credit cost before you begin. Built for real workflows: • Text to 3D and image to 3D • Optional AI-created source image when you do not have one • Optional styles that guide appearance without replacing the subject • Quality choices shown without technical provider names • Local model library with preview, share, re-download, and delete • Exports for web, Apple AR, games, 3D editing, and 3D printing • Transparent credits, fair-use limits, and automatic refunds for confirmed failures No account is required.

Manage or cancel in your Apple Account subscription settings. Weekly, monthly, and annual plans include recurring credits. Active members can purchase optional extra credit packs; purchased extra credits do not expire and remain usable after membership ends.
