OnDevice Forge - describe the feature, get the Apple on-device AI scaffold

Describe an AI feature for your iOS/iPadOS/macOS app - paste your Swift types alongside - and get the complete Apple FoundationModels integration: an honest Strong fit/Workable/Poor fit verdict, 1-4 compilable Swift files (@Generable models mirroring your types field-for-field, an availability-gated SwiftUI view, session code with instructions, snapshot streaming, tool calling when needed), integration notes in wiring order and the real limits (4,096-token window, device eligibility). A free in-browser fit scan sizes up the feature before you run anything. Derived from the @affaan-m/foundation-models-on-device skill (MIT).

Every public app is built from a security-scanned skill and must pass a clean scan — skill and frontend — before it can be listed. Have a skill of your own? Turn it into an app — or read the step-by-step walkthrough.
