ChatGPT is way better than Siri as an AI assistant.

While we wait for Apple to catch up in this department, here’s a cool hack that will allow you to summon ChatGPT from Siri, either by tapping the app icon on your phone, or by telling Siri “Hey GPT”.

Watch the full video tutorial or follow the steps below:

Step 1

On your iPhone or iPad, access this Apple Shortcut.

Tap Set Up Shortcut.

You will need to add your ChatGPT API key. You will need the paid version of ChatGPT for this.

Go to and find the API keys page. Click Create New Secret Key.

Copy the key and paste it back into the Shortcut app. Tap Add Shortcut.

Step 2

You will find the Hey GPT in your Shortcuts tab in the Shortcuts app. Tap the three little dots.

Here you will see the code for the Shortcut. Tap the down arrow and then Add to Home Screen.

And there you go, you got ChatGPT on your iPhone!

If you get this “no value was found” issue, it’s because your API isn’t allowed to spend credits yet. Go to your API usage limit, and set them as follows:

Bonus: this also works on the Apple Watch.
