Connect iOS 18 Siri to ChatGPT: Setup and Tips

Connecting Siri to ChatGPT lets Siri hand suitable questions to ChatGPT for a more detailed answer, and you can choose whether to send a request each time. You need an iPhone that supports Apple Intelligence, iOS 18.2 or later, and access to the relevant Apple Intelligence settings; availability depends on your device, language, and region.

What You’ll Need

An iPhone model that supports Apple Intelligence. Support is limited to compatible newer models; check Apple’s current device and regional availability information if the option does not appear.
iOS 18.2 or later. The ChatGPT integration was added in iOS 18.2, not the initial iOS 18 release.
Apple Intelligence enabled, with a supported device language and Siri language. The available languages and regions can change as Apple expands support.
An internet connection. You can use the integration without signing in to a ChatGPT account, or connect an account if you want your eligible account features and history.

Step-by-Step

Update iOS. Open Settings > General > Software Update. Install an available update that brings the phone to iOS 18.2 or later. Keep the phone connected to Wi-Fi and power during a major update.
Turn on Apple Intelligence. Go to Settings > Apple Intelligence & Siri. Turn on Apple Intelligence if the control is available, then allow time for required files to download. The exact screen and availability can differ by region, device, and software release.
Open the ChatGPT settings. In Settings > Apple Intelligence & Siri, tap ChatGPT. On some releases, you may first need to tap Extensions and then choose ChatGPT. If you do not see either option, check the troubleshooting section below.
Choose whether to sign in. Tap Set Up or the sign-in option shown. To use the integration without an account, choose the option to enable ChatGPT without signing in, if offered. To link an account, choose Sign In and follow the on-screen instructions. The available sign-in methods can vary.
Review the confirmation prompt. Follow any prompts explaining what information may be sent to ChatGPT. You can generally ask Siri to use ChatGPT without enabling automatic sharing of requests. Review the current privacy details on the setup screen before proceeding.
Check the confirmation setting. Under the ChatGPT settings, look for Confirm ChatGPT Requests. When confirmation is on, Siri asks before sending a request to ChatGPT. Turn it off only if you prefer eligible requests to be sent without that extra confirmation. Image or file-related requests may still require approval.
Try a request. Activate Siri with your usual method, then say something explicit, such as “Ask ChatGPT to suggest three names for a houseplant.” If Siri asks whether to send the request, confirm it. You can also try a question that benefits from a longer explanation, then check that the response appears on screen or is read aloud.
Use it with context when appropriate. Siri may offer ChatGPT for requests involving text, images, or documents, depending on the task and your device. When you want ChatGPT specifically, say “Ask ChatGPT…” or accept Siri’s offer. Check the prompt before sending anything private.

Common Mistakes

Expecting the feature on every iOS 18 phone. Installing iOS 18 alone is not enough. Apple Intelligence and its ChatGPT extension require compatible hardware and supported settings.
Looking for the setting in the ChatGPT app. The connection is configured in iPhone Settings under Apple Intelligence & Siri, not by simply installing or opening the ChatGPT app.
Assuming Siri sends every question to ChatGPT. Siri handles many requests itself. Say “Ask ChatGPT” when you want to direct a request there.
Turning off confirmation without considering privacy. The confirmation control changes how requests are handed off. It does not make a request private; review what will be shared before approving it.
Confusing account sign-in with activation. In supported configurations, the integration can be enabled without signing in. Signing in is optional, though account access may affect available features and history.

Tips

Be specific about the task and the format you want: for example, ask for a short summary, a comparison, or a list of ideas.
Use the phrase “Ask ChatGPT” if Siri answers a basic question itself or does not offer the handoff.
Keep confirmation enabled if you want a chance to review each handoff. You can change the choice later in the ChatGPT settings.
Check the current Apple Intelligence language and region requirements if the feature is missing. The iPhone’s language and Siri’s language may both matter.
For sensitive material, avoid sending details you would not want processed by an online service. Read Apple’s and ChatGPT’s current privacy information for how requests are handled.

Troubleshooting

ChatGPT is missing from Settings: Confirm that the iPhone model supports Apple Intelligence, update to iOS 18.2 or later, and check Settings > Apple Intelligence & Siri. Make sure Apple Intelligence is available for your region and configured languages. If a download is pending, connect to Wi-Fi, plug in the phone, and wait before checking again.

Siri does not hand off the request: Say “Ask ChatGPT” at the start of the request, verify that the ChatGPT extension is enabled, and check your internet connection. Try a different, clearly worded request. Siri may answer directly when it determines that a handoff is unnecessary.

The request is not sent: If Confirm ChatGPT Requests is on, watch for Siri’s confirmation prompt and approve it. For an image or document request, follow any additional permission or confirmation prompt. If you chose to sign in, reopen the ChatGPT settings and check whether the account connection is still active.

Setup is stuck or the feature still does not appear: Restart the iPhone, install any available iOS update, and revisit the settings. Check Apple’s current support information for device, language, and regional eligibility. Menu labels can vary slightly between iOS releases.
