Kuzco
On-Device AI SDK for iOS (LLMs, Vision and Stable Diffusion)
Last verified:
What is Kuzco?
Kuzco is an on-device AI SDK for iOS apps, built for Swift and SwiftUI. It lets developers run text generation, vision AI, and image generation locally on Apple devices without sending data to the cloud. The website emphasizes privacy-first design, offline operation, and a simple API that can be shipped in a few lines of code.
The SDK is aimed at developers who want to add AI features to iPhone, iPad, Mac, and Vision Pro apps while avoiding per-token API fees and external inference calls. It includes a model manager for downloading and managing models, real-time streaming responses, and SwiftUI-ready UI components for chat experiences. The product page also highlights support for a growing set of models and optimized model sizes.
A major focus is performance on-device. Kuzco says it supports up to 32K context, works across all Apple devices, and is designed for offline use with no internet required. The site also positions it as faster than Apple Intelligence in its own benchmark callout and notes that it can handle text, vision, and image workflows locally.
The waitlist page is for early access rather than an immediate public signup flow. Joining the waitlist means you’ll receive occasional updates and an invite when the team is ready, with no credit card required and a stated privacy promise that emails are not shared. Overall, it appears best suited for Apple-platform developers, indie builders, and teams that care about privacy, offline capability, and predictable costs.
