ChatGPT Action Button iPhone: Step-by-Step Guide to Launching ChatGPT with a Single Press
OpenAI has introduced a shortcut to launch ChatGPT voice mode using the iPhone 15 Pro’s action button. This new feature provides users with a hands-free AI assistant experience, extending conversational capabilities beyond Siri.
If you’ve ever wondered if you could replace Siri with something even faster, OpenAI may have handed you the next best thing. Thanks to a recent update to the ChatGPT iOS app, iPhone 15 Pro and newer users can now turn the action button into a shortcut that instantly launches ChatGPT’s voice mode. outcome? A hands-free, conversational assistant that feels a lot like the AI sidekick Apple never gave you.
According to MacRumors, this neat trick turns the action button into a “one-press portal” to ChatGPT, giving users immediate access to the chatbot’s powerful voice capabilities. While Apple still keeps Siri firmly tied to the side button, this solution makes it easier than ever to talk to OpenAI’s assistant without having to manually open the app.

The Action button, introduced with the iPhone 15 Pro (Review) was already one of Apple’s most flexible features, letting users assign shortcuts for actions like launching the camera, turning on the flashlight, or recording a voice memo. Now, with the update to OpenAI, you can use the same button to directly summon ChatGPT’s voice mode.
It’s a clever way to get around Apple’s limitations. You can’t technically replace Siri, but you can create an experience that feels remarkably similar and in some ways more advanced. ChatGPT can have relevant, open conversations that Siri still struggles to handle. As MacRumors points out, setup is quick and completely seamless once configured.
OpenAI’s iOS app already supports both text and voice input, but until now, users had to manually open the app and select voice mode every time. This new action button shortcut eliminates all that friction, letting you go straight into spoken chat, no menus, no taps through the screen.
How to set up ChatGPT on your iPhone’s action button
It takes just a few minutes to set up the feature. Here’s how to do it:
Step 1: Download and install the ChatGPT app from the App Store, and sign in.
Step 2: Go to Settings on your iPhone and tap the Action button.
Step 3: Under the Controls section, tap the chevron next to your current shortcut.
Step 4: Use the search bar to look for ChatGPT.
Step 5: Select Open ChatGPT Voice.
That’s it. From now on, holding down the action button will immediately launch ChatGPT’s voice interface. The first time you try it, you may be asked to allow microphone access, and simply tap Allow to continue.
Once set up, the experience is impressively intuitive. A recent app update means voice chats now take place in the same thread as your text conversations, displaying both written and spoken responses together. The interface feels natural, allowing you to switch between typing and talking without losing the context of your conversation.
You can also multitask. If you exit the app in the middle of a chat, the conversation is reduced to a dynamic island that shows whether ChatGPT is still listening or generating replies. To end a session, simply tap Dynamic Island and hit End within the app.
A smarter assistant, not a full Siri replacement
Of course, this integration doesn’t make ChatGPT a system-level assistant, at least not yet. It can’t perform iOS functions like setting reminders, opening apps, or checking your calendar. Siri still controls those basic functions. But for those who want richer, more conversational interactions, ChatGPT’s action button shortcuts are a game-changer.
It’s also a subtle sign of how quickly the AI assistant landscape is changing. With companies like OpenAI, Google, and Anthropic working to make voice AI feel more human, Apple’s long-standing dominance of the voice assistant field suddenly looks less secure.
However, for now, this new shortcut is the easiest way to give your iPhone a serious AI upgrade. Whether you’re dictating a message, brainstorming ideas, or just curious about what an AI poet sounds like, a press of the action button can now summon ChatGPT, ready to chat, no taps required.
