The Jetwriter AI extension works in Chrome, Edge, Brave, Opera and Vivaldi on a computer, on any website you open there. Gmail, Outlook on the web, WhatsApp Web, LinkedIn, Slack, X, Zoho Mail, Zendesk and Freshdesk also get an **AI Reply** button. It doesn't run in Firefox, Safari, desktop apps or on phones: there, use the web app at [jetwriter.ai/app](https://jetwriter.ai/app), with the same account.

## Browsers

| Browser | Works? |
| --- | --- |
| Chrome | Yes, from the Chrome Web Store. |
| Edge | Yes, from Edge Add-ons. |
| Brave, Opera and Vivaldi | Yes, from the Chrome Web Store. |
| Firefox and Safari | No: there's no version for them. Use the web app at jetwriter.ai/app. |

The extension runs on Windows, Mac, Linux and Chromebooks. To add it, see [Install the Jetwriter AI extension](https://jetwriter.ai/help/install-jetwriter).

## Sites with an AI Reply button

These sites get Jetwriter's own **AI Reply** button, which reads the conversation you're answering. Open them in the browser, at these addresses:

| Site | Open it at |
| --- | --- |
| Gmail | mail.google.com |
| Outlook on the web | outlook.live.com, outlook.office.com, outlook.office365.com or outlook.cloud.microsoft |
| WhatsApp Web | web.whatsapp.com |
| LinkedIn | linkedin.com, in messages and in a post's comment box |
| Slack | app.slack.com |
| X | x.com |
| Zoho Mail | mail.zoho.com, or your region's mail.zoho address |
| Zendesk | your company's zendesk.com address |
| Freshdesk | your company's freshdesk.com address |

In Gmail and LinkedIn, a new message gets **AI Compose** instead. For the steps in each app, see [Reply to an email in Gmail with AI Reply](https://jetwriter.ai/help/reply-in-gmail), [Use Jetwriter in Outlook on the web](https://jetwriter.ai/help/outlook-web) and [Reply in WhatsApp Web with Jetwriter AI](https://jetwriter.ai/help/reply-in-whatsapp-web).

To ask for another site, open Jetwriter, click your profile icon at the top of its window, choose **Request Integration**, and enter the site.

## Any other website

Jetwriter works on every other website too, without a button of its own:

-   select text and use the toolbar that appears, to fix, rewrite or translate it, or to ask about it;
-   or press Ctrl+Shift+K (Cmd+Shift+K on a Mac) to open Jetwriter, write, then copy or insert the result.

See [Open Jetwriter on any page, and change the shortcut](https://jetwriter.ai/help/ways-to-open-jetwriter). It can't open on the browser's own pages, such as settings and the new tab page, or on the Chrome Web Store: there it says "Extension is not supported on this page. Please visit a regular website like Gmail and then launch this extension."

## Desktop apps

The extension only runs inside the browser, so it doesn't appear in apps you install on your computer: Outlook for Windows or Mac, Apple Mail, Thunderbird, or the WhatsApp and Slack apps. Open the same service's website in your browser instead, such as Outlook on the web or WhatsApp Web, or paste the message into the web app.

## Phones and tablets

The extension doesn't run on phones and tablets, so there's no **AI Reply** button on an iPhone, iPad or Android phone. Use the web app at [jetwriter.ai/app](https://jetwriter.ai/app) in your phone's browser: paste the message, then copy the reply. On Android, there's also the Jetwriter AI app on Google Play. See [Use Jetwriter on your phone](https://jetwriter.ai/help/jetwriter-on-your-phone).

If you use [Auto-Drafts](https://jetwriter.ai/help/auto-drafts), its drafts appear in the Gmail app on your phone too.

## The web app works in any browser

The web app at [jetwriter.ai/app](https://jetwriter.ai/app) works in every browser, Firefox and Safari included, on a computer or a phone. It uses the same account and plan as the extension. It has no **AI Reply** button: you paste the message you're answering and copy the reply back.
