Use ChatGPT in your browser
The ChatGPT web app is simply ChatGPT running at chatgpt.com. It opens in any modern browser — Chrome, Safari, Edge or Firefox — on Windows, macOS, Linux, Android or iOS. There is nothing to download: open the page, sign in with your OpenAI account, and start chatting.
Because it signs in with the same OpenAI account, your conversation history is shared with the official mobile and desktop apps. You can begin a chat on your phone and continue it in your browser on a laptop.
Why people use the web app
- No install: useful on shared, locked-down or work computers where you cannot install software.
- Cross-platform: the same page works on practically any device with a modern browser.
- Always current: you load the latest version each time, with no manual app updates.
- Same account: history and settings follow your OpenAI account across web and apps.
Add it to your home screen (PWA-style shortcut)
On mobile, you can add chatgpt.com to your home screen so it opens like an app. Open chatgpt.com in your browser, tap the browser's Share or menu button, and choose Add to Home Screen. The exact wording varies by browser and device. This creates a shortcut to the web app; it is not a separate install from an app store.
Web app vs the native apps
The web app and the native apps share your account and history. The native apps can add conveniences — a home-screen icon out of the box, a global keyboard shortcut on desktop, or tighter system voice integration. The web app's advantage is that it works everywhere with no install. Capabilities change over time, so verify current details on OpenAI's help center.
Make sure you are on the official web app
The official ChatGPT web app is at chatgpt.com. To avoid look-alike sites, type the address directly rather than clicking ads or unknown links. If you prefer a native app, follow our iPhone, Android or desktop guides, and read official vs fake ChatGPT apps before installing anything.
Use more than ChatGPT
Want ChatGPT, Claude, Gemini, Grok and more in one place?
MultipleChat is useful when you do not want to jump between separate AI tabs. You can use multiple leading AI models, compare answers side by side, generate images, work with documents, and use AI Collaboration when one answer is not enough.
Privacy-first: MultipleChat doesn’t save your chats to memory and doesn’t share your data with model providers or let them train on it.
