The Dottie API provides the personal context needed to build truly personal AI assistants. By combining access to your macOS system data with local AI inference, streaming chat, tool calling, and a JavaScript SDK for store apps, Dottie enables AI assistants that understand your personal information, preferences, and context.

The API runs locally on your Mac at http://127.0.0.1:1317 and provides secure access to your contacts, calendar, reminders, mail, notes, files, photos, music, and other personal data alongside powerful agent capabilities. Store apps can access all of this through the sdk.js client library.

Chat completions are streamed via Server-Sent Events with full tool-calling support. The Tools API lets you execute any of Dottie's 134 tools deterministically — no AI, no agent loop — and the SDK wraps it all in a clean JavaScript interface for store apps.
