What is iChatWithGPT?

iChatWithGPT is an AI assistant that runs inside iMessage, reachable from iPhone, Apple Watch, Mac, CarPlay and Siri. It answers questions, browses the web, sets text reminders and generates images, with a free tier and a Pro upgrade for unlimited messaging.

iChatWithGPT puts an AI assistant inside iMessage, so questions and answers happen in the same thread you already use for texting. There is no app to install: the service is designed to be reached from an iPhone, Apple Watch, MacBook, CarPlay and Siri, and the site notes that the setup page needs to be opened on an iPhone or Mac. A short invite flow adds the assistant as a contact, after which it behaves like any other text conversation. The assistant handles several everyday jobs in one place. It performs AI powered web research for recommendations, news summaries, weather forecasts and game results, sets simple text reminders to keep habits and mental to-dos on track, and generates images from short prompts, which the site frames as an artist in your pocket. Because the contact is stored in the address book, voice commands such as asking Siri to text GPT make the assistant usable hands-free, including from a car. The tool is built for people who want occasional AI help without another tab or subscription app cluttering their phone. Casual users, commuters and anyone who already lives in Messages are the obvious audience; heavy prompt engineers will find the interface deliberately minimal. The site states that no signup is needed and that no identifying information is collected, which lowers the barrier for a quick first test. Under the hood, responses are powered by GPT-5.6, Claude 4.8, Google Search and Nano Banana, according to the homepage. A free tier exists, and a Pro upgrade for unlimited messaging can be requested by asking the assistant directly. The natural comparison is with Apple Intelligence or a standalone ChatGPT app: iChatWithGPT trades depth of settings for zero-friction access inside the messaging app people already have open.

How do you use iChatWithGPT?

1Open the start page on an iPhone or Mac
The onboarding flow only works on Apple hardware. Visit the start chatting link from your iPhone or Mac to begin the invite process.
2Enter your phone number to request an invite
Provide a valid phone number on the homepage form. The assistant is added to iMessage once the invite is processed.
3Save the assistant as a contact
Add the number to your address book so it appears under a name. This is also what enables the Siri voice command later.
4Send your first message or use Siri
Text a question, ask for a reminder or request an image. Alternatively say a Siri command to send the message hands-free.
5Upgrade to Pro from inside the chat
When the free allowance runs low, ask the assistant about Pro. The homepage says the upgrade is handled through the conversation itself.
