How to use ChatGPT with Siri on iPhone in iOS 18.2

At the time when Apple published its iOS 18.2 update, it brought several new Apple Intelligence features to your iPhone 16 (or iPhone 15 Pro Max), mainly centered around the generation of images and visual intelligence on the iPhone 16. At the same time, Apple has also integrated chatgpt into its IA tools, including Siri, and it can be incredibly useful. Here are all the places where chatgpt has been added to iOS and how you can use them to turbocharger AI on your iPhone.

Note: This article focuses on the iPhone, but you can also use chatgpt on an iPad or Mac.

What is the Chatppt?

Chatgpt is a generative artificial intelligence chatbot developed by Openai. It can generate text, speech and images depending on the user prompts, including code, tests, drawings and music. On the iPhone, it is mainly used to provide answers to certain requests to which Siri is unable to answer, including questions about photos and documents.

On iOS 18 iOS 18, the Chatppt is fueled by the GPT-4O model, but in iOS 26, it will get an upgrade to the last GPT-5 model which was launched in August 20205. According to Openai, GPT-5 is “a unified system that knows when to respond quickly and when to think longer to provide expert responses”.

Activate ChatPPT

You don’t need a chatgpt account to start using it on your iPhone, but you have to activate it. Open the settings> Apple Intelligence & Siri And look for it Cat Menu under the “Extensions” section. If and when Apple incorporates other AI services, they will also appear here.

In the chatgpt menu, press Facility... And you will get a pop-up card indicating what you can do with chatgpt. Press Next, then on the following card, press “Activate Chatgpt” or “Use Chatgpt with an account”.

You will also see a “confirm Chatgpt” rocking which is activated by default. Whenever Siri or any other AI tool wants to use Chatgpt, you will be invited first. Turnout it will allow you to discuss without interruption, but you will always be asked before sending a kind of image to Chatgpt, whatever the way you define this rocking.

Apple sharing very limited information with OPENAI, only what is strictly necessary to meet the demand, but to leave this activity means that you must opt each request. This can be a good thing, but if you are not so worried or embarrassed by constant requests, you can deactivate it so that your interaction flow is much more fluid.

Connect to your Chatgpt account

If you want to connect to your Chatgpt account later, you will find a Connect Option in the chatgpt menu. Be signed will keep a recording of all your chatgpt requests in your Chatgpt account – when you use the Chatgpt application (mobile or office), you will find the history of all your Siri chatgpt requests and elsewhere in iOS.

There is a daily limit to the number of “advanced” requests that you can make if you are not a chatgpt subscriber, and you will see a note on this page if you have exceeded the limit. You will get “basic” results that are less advanced to the next day. If you have a chatgpt plus subscription, you connect allows you to make all the advanced requests you want.

Chatgpt in Siri

Now that the GPT cat is on, let’s start using it. The most important place to use Chatgpt is when interacting with Siri. As long as chatgpt is activated, Siri automatically turns to Chatgpt for everything he does not know the answer. This means that the answers involving personal information on your phone will always be managed by Siri, as well as certain questions of general knowledge, but the Chatppt can answer much more than Siri.

You can also force Siri to use Chatgpt even on a question that he would normally answer, adding “asking the chatppt” before. “Hey Siri, ask Chatgpt if dogs can eat broccoli” gives you a response from the Openai chatbot instead of Apple.

The real pleasure begins when you ask Chatgpt to do things Siri Never do. Try “Ask Chatgpt to compose a short letter of thank you to my mother” or “ask Chatgpt to create a two -day route for visiting San Francisco”.

You can even use OPENAI image generation tools. For example, in the example below, I asked Chatgpt to create an image of a Siamese cat in a ninja holding. Chatgpt image generation capacities are much more advanced and less restrictive than image game image.

Chatgpt can also analyze the images and what is on your screen. If you tell Siri to ask Chatgpt something on a web page you look at, you will be invited to send a screenshot or complete web page content to chat for an answer. For example, you can find an online recipe and ask Chatgpt to summarize it, or take a photo of certain ingredients and ask Chatgpt which dishes you can do with them.

When you look at a photo in the photo application, ask Siri to ask Chatgpt something about it, and you will be invited to send the image to Chatgpt for analysis.

With Apple Intelligence, any text box has the possibility of activating the writing tool menu (by pressing the Apple Intelligence button in notes and other applications, or by typing and holding in a text entry area). But in iOS 18.2, you will also see an option “compose” at the bottom of the contextual window of writing tools.

Press it and you will receive an prompt where you can describe what you want chatgpt writing. It can be a poem, a short invitation to a birthday party, a piece of fiction or a technical document. When done, you can be able to enter the invite window on the means of refining the exit or having the opportunity to simply rewrite it from your original prompt. You will even have some suggestions to a chatgpt.

The generation of chatgpt images works here too! Simply use a prompt that clearly shows that you are looking for an image rather than text, like the image below of a “sad puppy a rainy day …”

Chatgpt in visual intelligence

Visual intelligence is new on the iPhone 16 in iOS 18.2. Press the camera control button in the long term to launch a new camera search interface – NAP An image of a company to see notes and hours, a common product to see a link to its website, text to summarize or translate it, and more.

In addition to the “Research” button, you will see a persistent “Ask” button that will ask Chatgpt for what you look at. Chatgpt is capable of identifying many plants and animals, for example, and an entry area at the bottom of the screen allows you to ask follow-up questions like “Is it toxic?”, “How many calories does this have?”, Or “Does that have good criticism?”
