Apple Intelligence on the iPhone Duo is Apple's set of AI features, from Writing Tools to Visual Intelligence, plus Siri AI, a new version of Siri that Apple says can draw on your personal context across messages, emails, and photos. Apple lists the Duo as an Apple Intelligence device, and it ships with iOS 27.1. Two things are still to come: Siri AI is in beta and speaks English to start, and Apple says five more Siri AI languages arrive in October. Here is what Apple says the features do, what works at launch, and what is not yet known.
Key takeaways
- Apple lists iPhone Duo with A20 Pro as an Apple Intelligence device, and the Duo ships with iOS 27.1.
- Apple Intelligence uses on-device processing and Private Cloud Compute, according to Apple. Some server-based features have daily usage limits.
- Apple's feature list includes Writing Tools, Proofread, Siri AI, Visual Intelligence, Image Playground, Genmoji, Image Wand, Clean Up, Spatial Reframing, Extend, and Live Translation.
- Siri AI is in beta with iOS 27 and is available in English to start, and not initially in the EU.
- Apple says French, Japanese, Korean, Portuguese, and Spanish support for Siri AI is coming in October. MacRumors reports those languages are in the iOS 27.2 beta.
What runs on-device, and why it matters
Apple says Apple Intelligence protects privacy by using on-device processing and Private Cloud Compute. On-device processing means requests can be handled on the phone itself, and Apple says Apple Intelligence is aware of your personal information without collecting it. Larger requests can go to Private Cloud Compute, Apple's server system, where Apple says your data is never stored and is used only for your requests.
On the Duo, the on-device work runs on the A20 Pro's Dual 16-core Neural Engine. Our A20 Pro performance guide covers the chip in detail.
One practical point: not everything is on-device. Apple says certain Apple Intelligence features that rely on server-side models are subject to daily usage limits, which can vary by feature, request complexity, and system demand. Apple does not publish a list of which features work without a connection.
What Apple Intelligence does at launch
These are the features Apple lists on its Apple Intelligence page, with Apple's own description of each:
| Feature | What Apple says it does |
|---|---|
| Writing Tools | Generates drafts, gives feedback, and matches your writing style, punctuation, and tone |
| Proofread | Checks grammar and spelling virtually anywhere you type |
| Siri AI | A conversational assistant with richer answers and natural back-and-forth |
| Visual Intelligence | Search and take action on what is around you or on your screen |
| Image Playground | Creates images in virtually any style |
| Genmoji | Creates Genmoji to match the moment |
| Image Wand | Turns rough sketches into images |
| Clean Up | Removes even larger objects from photos |
| Spatial Reframing | Reframes a photo after it has been taken |
| Extend | Expands the edges of a shot |
| Live Translation | Translates texts in Messages and shows live translated captions in FaceTime |
Apple notes that some features may not be available in all regions or languages. For video calls on the Duo, our FaceTime guide covers the two front cameras and Duo FaceTime.
Siri AI on the Duo. Apple describes Siri AI as an entirely new version of Siri, rolling out in beta with iOS 27. Apple says it can draw on personal context to help you find what you need across messages, emails, photos, and more, and that you can write with Siri by simply describing what you need.
Siri AI languages: now and next
Apple Intelligence works with Siri and device language set to any of these, according to Apple: Chinese (Simplified), Chinese (Traditional), Danish, Dutch, English, French, German, Italian, Japanese, Korean, Norwegian, Portuguese, Spanish, Swedish, Turkish, or Vietnamese.
Siri AI is narrower. Apple says it is available in English to start and requires an Apple Intelligence device set to a supported language. Apple also says Siri AI will not be initially available in the EU on iOS.
| Siri AI language | Status |
|---|---|
| English | Available at launch, in beta (Apple) |
| French, Japanese, Korean, Portuguese, Spanish | Coming in October (Apple); in the iOS 27.2 beta (reported by MacRumors) |
Apple's Newsroom says support for French, Japanese, Korean, Portuguese, and Spanish is coming in October. It does not name the update. MacRumors reported that the iOS 27.2 beta adds Siri AI in those five languages and expects iOS 27.2 to arrive later in October. Treat the iOS 27.2 link and any specific date as reported, not confirmed by Apple. Our iOS 27 features guide covers the rest of the Duo's software.
The honest limits
- Untested on the Duo. Independent reviews of the iPhone Duo have not been published yet, so there are no measurements of how fast or accurate Apple Intelligence and Siri AI are on this phone. Anything you read about speed or quality before reviews arrive is a guess.
- Siri AI is a beta. Apple describes it as rolling out in beta with iOS 27, so expect it to change.
- Language timing. Apple says the five additional Siri AI languages are coming in October, but has not given a date or named the update.
- Region limits. Siri AI is not initially available in the EU on iOS, and Apple says some features may not be available in all regions or languages.
- Usage limits. Features that rely on server-side models are subject to daily limits, according to Apple.
