Source: Apple opening Siri to third-party apps, preparing a Siri SDK for release at WWDC, and developing an Amazon Echo rival
Apple is upping its game in the field of intelligent assistants. After years of internal debate and discussion about how to do so, the company is preparing to open up Siri to apps made by others.
Context & Ripple Effects
This May 2016 scoop is the origin point of a decade-long arc: after years of internal debate, Apple decides Siri should be a platform rather than a captive feature, with an SDK that ships as an API in iOS 10 weeks later at WWDC. The same report puts Apple on a collision course with Amazon's Echo in the living room, turning the assistant from a phone feature into a hardware battleground.
The through-line runs straight forward: the 2016 opening is followed by a planned Siri overhaul that would command all in-app features, then by the Apple Intelligence-era Siri with its own third-party app API, and ultimately by 2026 plans to run any AI service through App Store apps. Each step reopens the question this report first raised — who controls what an assistant can reach.
First-order effects
- iOS app developers get a new surface at WWDC: voice commands routed into their apps through the Siri SDK, making Siri integration a build decision alongside notifications and widgets.
- Amazon loses its head start narrative on assistant hardware the moment Apple confirms it is building an Echo rival of its own.
Second-order effects
- Google and Microsoft face pressure to match the openness play, since a closed assistant now reads as a competitive liability against one that accepts developer intents.
- Amazon's third-party skills ecosystem stops being a differentiator Apple lacks, forcing the Echo fight onto audio quality, pricing, and home integration instead.
Third-order effects
- If the cadence holds — API in 2016, app-control API under Apple Intelligence, any-AI-service access by iOS 27 — Siri hardens from a feature into an assistant distribution layer where Apple gates which intelligence reaches iPhone users, whatever model powers it.
The trend: Voice assistants are evolving from closed single-company features into platformized distribution layers, with Apple opening incrementally while keeping the gate.
