You don't have to turn off Apple Intelligence completely. You can disable the ChatGPT integration or even turn it off within apps, preventing Siri from making suggestions across all your apps.

You can disable Apple Intelligence completely, or you can turn off specific features, depending on your requirements.

If you decide that you'd rather not use Apple Intelligence on your iPhone, iPad, or Mac, you can easily disable it. Go to Settings > Apple Intelligence & Siri and toggle off Apple Intelligence.
