UI Mockup Studio
Use the UI Mockup Studio to design realistic chat screenshots, Direct Message screens, notifications, and social feed previews for UX prototypes, education, product demos, and presentation drafts. Mockups render in the browser editor and should only be used for legitimate design, planning, or instructional contexts.
No file upload is required for the standard workflow. Processing happens in the current browser session unless you choose a separate account or export feature.
