Apple is preparing to let European iPhone users replace Siri with third-party voice assistants like Google Assistant, Gemini, or ChatGPT. This ends Siri’s exclusivity since its 2011 debut. The change responds to the EU’s Digital Markets Act, which requires gatekeeper platforms to promote fair competition. Apple must now allow users to override built-in defaults, marking a significant policy shift.
New “Default Assistant” Setting
Reports suggest iOS 18.5 and iOS 19 for EU devices will introduce a “Default Assistant” option. The update is expected in late 2025. Users will see a list of compatible assistants and select their preferred one. This setting will replace Siri at the system level, enabling third-party alternatives to handle core functions like messaging, navigation, and smart-home control.
Supported Third-Party Assistants
| Assistant | Developer | Core Functions Supported | Limitations |
|---|---|---|---|
| Google Assistant | Messaging, navigation, and smart-home control | No system-level controls (e.g., airplane mode) | |
| Gemini | General queries, task automation | Limited iOS integration | |
| ChatGPT | OpenAI | Conversational AI, knowledge queries | No background system access |
| Microsoft Copilot | Microsoft | Productivity tasks, web searches | Requires app integration |
| DeepSeek | DeepSeek | AI-powered searches, translations | New to iOS, limited features |
| Meta AI | Meta (Facebook) | Social media integrations, basic commands | Restricted system-level actions |
Technical and User Experience Limits
Despite the change, Siri remains deeply embedded in iOS. Features like “Hey Siri,” power-button activation, and lock-screen suggestions rely on private system hooks. Third-party assistants won’t fully replace these integrations. Users will mainly experience differences in voice-initiated app launches rather than a complete Siri substitution. This partial access may limit seamless functionality.

Siri’s AI Upgrade Delayed
Apple’s next-gen Siri, powered by a large language model, was unveiled at WWDC 2024 but faces delays. Expected in iOS 19, its release follows extended testing for bias reduction. Until then, third-party assistants may address some feature gaps. However, users might face fragmented experiences until Apple’s enhanced Siri arrives, potentially offering deeper integration.
A Symbolic Win for EU Users
This move represents a victory for user choice in the EU. However, practical benefits depend on how well third-party assistants integrate over time. Outside the EU, Siri remains the default, highlighting that this change is primarily regulatory compliance rather than a global iOS policy shift. The long-term impact on Apple’s ecosystem remains uncertain.
Conclusion
Apple’s decision to allow third-party assistants in the EU reflects regulatory pressure rather than a voluntary shift. While it increases user options, technical constraints may limit functionality. As Siri’s AI upgrade looms, the balance between compliance and seamless user experience will shape Apple’s future voice assistant strategy. For now, EU users gain choice but with trade-offs.
