As an Apple user you have access to the possibilities of chatgpt in combination with Apple Intelligence at system level. The OpenAI-Chatbot supports Apple Intelligence by strengthening Siri with in-depth answers and is able to answer complex questions immediately.
In addition, ChatGPT is integrated in Writing Tools (Writing Aid) to generate texts based on descriptions, which increases the productivity and creativity of users. Those who own a chatgpt (premium) account can link it directly to Apple Intelligence for iPhone, iPad and Mac.
Support Apple Intelligence
Apple Intelligence can currently be used via a detour in the EU and can also be used in the EU from macOS 15.1, iOS 18.4, iPados 18.4 and Visionos 2.4 when you change the language of your device and Siri to English vs. All supporting devices and languages ​​can be found here.
Chatgpt link to Apple Intelligence
- Open Settings (Settings) on your iPhone or iPad
- Go to ‘Apple Intelligence & Siri’
- Tap ‘chatgpt’
- If necessary, switch on the option
- Tap ‘sign in’ (log in) at ‘Chatgpt account’
- Follow the steps to log in

On a Mac you can set this via  ▸ System settings (system settings) ▸ Apple Intelligece & Siri ▸ Chatgpt ▸ Set up (configure) ▸ Sign in (log in).
No Chatgpt Subscription required
If you want to use chatgpt in an app, you normally have to take out a paid subscription. After this you get an API key, with which an app gets access. For users of Apple Intelligence, such a subscription is no longer necessary. You get access to the generative functions for text and images associated with the GPT-4O data model through Apple Intelligence.
Existing chatgpt subscribers can link their account and use features paid directly from the apps. Do you choose to link your own account? Then the Chatgpt policy applies to data use.

Daily limits
Just like on the Chatgpt website and also under iOS, iPados and macOS daily limits. The free version of Chatgpt has restrictions compared to the paid version, such as less access to advanced functions and possibly longer waiting times during busy periods. The number of (rapid) requests is also limited. With the help of Chatgpt Plus you can lift the limitations, also for Apple Intelligence. By logging in with your account you can unlock this.
Privacy after logging in
When you use chatgpt within Apple Intelligence, your privacy depends on how to configure integration. If you use the AI ​​without a chatgpt account, only your request (after permission) and any attachments (such as documents or photos) will be sent to OpenAI. Your IP address is hidden, and OpenAI may not store or use your data to train its models, unless this is required by law.
If you log in with your chatgpt account, your interactions fall under the privacy conditions of OpenAI, which means that your requests and attachments may be stored and used to improve models.
