iOS 27: Siri Now Supports ChatGPT, Claude & Gemini — Here’s How to Enable It in 2026

iOS 27 is set to revolutionize Siri by allowing third-party AI chatbots like ChatGPT, Claude, and Gemini to power its responses — marking Apple’s biggest AI shift since 2011. According to 9to5mac.com, Apple will open Siri’s backend via a new API, letting users choose their preferred AI model for complex queries. This isn’t a replacement for Apple’s core AI but a customizable layer built on top — putting user choice at the center.

How Third-Party AI Will Transform Siri’s Capabilities

When you ask Siri a complex question — like ‘Summarize this article’ or ‘Compare these two laptops’ — iOS 27 will prompt you to select your preferred AI provider: ChatGPT, Claude, Gemini, or even a niche app from the App Store. Your choice becomes a saved preference, so future similar queries auto-use your selected AI.

This feature doesn’t remove Apple’s partnership with Google for basic Siri functions. Instead, it adds a user-controlled AI layer that adapts to your needs: privacy-focused users pick Claude, real-time data seekers choose Gemini, and productivity fans may opt for ChatGPT.

How to Choose Your AI Chatbot in iOS 27

Once iOS 27 launches this fall, navigate to Settings > Siri & Search > AI Assistant. Here, you’ll see toggle options for:

• Default Apple AI
• ChatGPT (OpenAI)
• Claude (Anthropic)
• Gemini (Google)
• Other approved third-party apps

You can even set different AI defaults for different contexts — e.g., use Claude for personal notes, Gemini for research.

Privacy & Security: Apple’s On-Device AI Promise

Apple insists all third-party AI interactions will respect its privacy-first principles. Queries will be encrypted end-to-end, and sensitive data won’t leave your device unless you explicitly opt in. Developers must comply with App Tracking Transparency, App Privacy Report, and on-device processing standards to be approved.

ChatGPT vs Claude vs Gemini: Siri Performance Comparison

Each AI brings unique strengths to Siri:

• ChatGPT: Best for creative writing, coding help, and long-form reasoning.
• Claude: Superior for summarization, privacy-sensitive tasks, and ethical reasoning.
• Gemini: Strongest in real-time web search, image analysis, and Google ecosystem integration.

Early beta testers report that switching between them feels seamless — no app switching required.

This update isn’t just a feature — it’s a strategic pivot. Facing regulatory pressure in the EU and U.S., Apple avoids antitrust risks by enabling open AI access while keeping its hardware and services revenue intact. For users, it means finally having control over their digital assistant’s personality and intelligence.

With beta testing underway, iOS 27 is expected to launch this fall. Keep an eye on the WWDC 2026 keynote for official confirmation.
