Apple Intelligence is capable of processing basic requests, rewriting text, and even creating images through the Image Playground app. However, sometimes requests are too complex for Apple’s AI, but iOS 18’s ChatGPT integration means your iPhone can fall back on it when Apple Intelligence fails.

  7. Daily Limit will tell you whether you are under or over your daily limit of ChatGPT requests. On the free tier, you can use ChatGPT’s advanced features until you reach the daily limit, after which you will be limited to a more basic version of the AI.

  8. You can tap Upgrade to ChatGPT Plus to upgrade your ChatGPT to the premium tier which gives you a higher request limit.

  9. If you keep Confirm ChatGPT Requests enabled, Siri will always ask for you to confirm whether you want to route a request to ChatGPT instead. If you disable this toggle, Siri will automatically send your requests to ChatGPT without asking you first. I recommend leaving this toggle enabled.

  10. Whenever a request is too complex for Siri, you will be prompted to Use ChatGPT (you can still opt to Search the Web instead if you do not want ChatGPT to have access to your request).
