Axint

The Apple-native execution layer for AI agents.

Context tells agents what to build. Axint makes it shippable on Apple.
Open-source compiler that turns TypeScript into validated Swift —
App Intents, SwiftUI views, WidgetKit widgets, and full apps.

Why Axint

Apple's API surfaces — App Intents, SwiftUI, WidgetKit — are verbose. A single widget needs a TimelineEntry, a TimelineProvider, an EntryView, and a Widget struct before you've written a line of business logic. AI coding agents pay per token, and all that boilerplate adds up fast.

Axint compresses it. One defineIntent() call replaces 50–200 lines of Swift. One defineWidget() replaces an entire WidgetKit stack. The compiler handles the struct conformances, the @Parameter wrappers, the LocalizedStringResource literals — everything an agent would otherwise have to generate token by token.

Four surfaces, one pipeline:

defineIntent()  →  App Intent for Siri & Shortcuts
defineView()    →  SwiftUI view
defineWidget()  →  WidgetKit widget
defineApp()     →  Full app scaffold

The result: agents ship Apple features at 5–15× fewer tokens than hand-written Swift.

Quick start

npm install -g @axint/compiler

# compile a single file
axint compile my-intent.ts --out ios/Intents/

# or pipe to stdout
npx @axint/compiler compile my-intent.ts --stdout

Intent

import { defineIntent, param } from "@axint/compiler";

export default defineIntent({
  name: "CreateEvent",
  title: "Create Calendar Event",
  description: "Creates a new event in the user's calendar.",
  domain: "productivity",
  params: {
    title: param.string("Event title"),
    date: param.date("Event date"),
    duration: param.duration("Event duration", { default: "1h" }),
    location: param.string("Location", { required: false }),
  },
});

View

import { defineView, prop, state, view } from "@axint/compiler";

export default defineView({
  name: "EventCard",
  props: {
    title: prop.string(),
    date: prop.date(),
  },
  state: {
    isExpanded: state.boolean(false),
  },
  body: [
    view.vstack({ alignment: "leading", spacing: 8 }, [
      view.text("entry.title"),
      view.conditional("isExpanded", [view.text("entry.date")]),
    ]),
  ],
});

Widget

import { defineWidget, entry, view } from "@axint/compiler";

export default defineWidget({
  name: "EventCountdown",
  displayName: "Event Countdown",
  description: "Shows time until the next event.",
  families: ["systemSmall", "systemMedium"],
  entry: {
    eventName: entry.string("Untitled"),
    minutesUntil: entry.int(0),
  },
  body: [
    view.vstack({ alig
