TinyAI

TinyAI targets a very specific gap: moments when you need an AI assistant but have no usable connection. Instead of calling a cloud API, the app downloads a compact language model to your device and runs inference locally, so it works on a plane, in a basement or anywhere coverage drops. The developer has repeatedly shrunk the model size across updates to widen device compatibility, and recent versions let you pick which model to download based on your phone's capabilities.

The app's selling point is privacy by architecture rather than by policy: per Apple's App Store listing, the developer collects no data, because prompts and responses never leave the device. It also handles the simple utility cases well — quick arithmetic, short questions, casual back-and-forth — positioning itself as a wittier, offline alternative to a standard voice assistant.

Be realistic about the trade-offs. On-device models of this size are noticeably slower and less capable than frontier cloud models, and user reviews describe occasional quirks such as a generation not stopping cleanly or older devices struggling. The app is free to download with optional in-app purchases that act as tips, and it requires iOS 16 or later.
