Apple’s Foundation Models framework unlocks new app experiences powered by Apple Intelligence

With the release of iOS 26, iPadOS 26, and macOS 26, Apple is empowering developers to integrate on-device AI capabilities through the Foundation Models framework, the core of Apple Intelligence. This framework allows developers to create intelligent, privacy-protected, and offline AI experiences at no cost. Apps across health, fitness, education, creativity, and productivity are already leveraging it to transform user experiences.

For instance, SmartGym uses AI to build custom workout plans and summaries, while Stoic offers adaptive journaling prompts. CellWalk delivers conversational explanations of biological terms, and Stuff organizes tasks through natural voice or handwriting input. Creative tools like VLLO and Signeasy now generate personalized content and smart summaries, while Agenda and OmniFocus use AI to streamline workflows.

The Foundation Models framework, built into Swift, supports structured and guided AI responses, enabling developers to integrate intelligent features seamlessly without relying on cloud processing. Running entirely on-device, it ensures user data stays private while offering responsive, real-time AI experiences across Apple devices — redefining how apps learn, create, and interact with users.
