# Use Jetwriter in Outlook on the web > Jetwriter adds AI Reply to Outlook in the browser, under an open email and next to Send. It doesn't work in the Outlook desktop apps. - Applies to: Every plan. Outlook on the web in Chrome, Edge, Brave, Opera or Vivaldi on a computer, work and personal accounts - Updated: Nov 7, 2026 - Web page: https://jetwriter.ai/help/outlook-web Jetwriter AI works in Outlook on the web, the version of Outlook you open in your browser. Open an email and click **AI Reply** under it, or click **AI Reply** next to **Send** in a reply or a new email. Say in a few words what to write, then click **Insert** and send the email from Outlook yourself. Jetwriter doesn't appear in the Outlook desktop apps for Windows or Mac. You need the Jetwriter AI extension (formerly ChatGPT Writer) in Chrome, Edge, Brave, Opera or Vivaldi on a computer, and you need to be signed in to it. Each email uses one AI response from your plan; the Free plan includes 15 a month. ## Which Outlook works Jetwriter works when the address bar shows one of these addresses: | Address | Used for | | --- | --- | | outlook.live.com | Personal accounts: Outlook.com, Hotmail and Live | | outlook.office.com | Work and school accounts (Microsoft 365) | | outlook.office365.com | Work and school accounts (Microsoft 365) | | outlook.cloud.microsoft | Work and school accounts (Microsoft 365) | It doesn't work in Outlook for Windows (classic or new), Outlook for Mac, or the Outlook app on a phone, because the extension only runs inside a browser on a computer. If you use one of those apps, open your mailbox in the browser instead: sign in at outlook.live.com for a personal account, or outlook.office.com for a work or school account. ## Reply to an email 1. In Outlook on the web, open the email you want to answer. 2. Click **AI Reply** (1), under the email next to Outlook's **Reply**. Outlook opens a reply to everyone on the email (**Reply all**), and the Jetwriter window opens. ![An email open in Outlook on the web, with the AI Reply button between Outlook's Reply and Forward buttons under the message.](https://jetwriter.ai/images/help/outlook-web/ai-reply-below-email.webp) AI Reply shows under every email you open in Outlook on the web. *Numbers in the screenshot:* (1) AI Reply 3. In the box that says "Tell AI what to write (e.g., 'Politely decline')", type what the reply should say, such as "Monday works, send me the new dates". A few words are enough: Jetwriter already reads the email thread. 4. If you like, pick a **Writing style** and a **Length**, then press **Enter** or click the send arrow. The reply appears in a few seconds. 5. Read it. To change it, type what to change in the box that says "Tell AI what to change (e.g., 'Shorter and more direct')" and send again. 6. Click **Insert**. The reply goes into Outlook's reply box and the Jetwriter window closes. 7. Check the reply and its recipients, edit it like any email, then click Outlook's **Send** (1). To write it again, click **AI Reply** (2) next to **Send**. ![A reply written by Jetwriter in Outlook's reply box, with Outlook's Send button and the AI Reply button next to it at the top.](https://jetwriter.ai/images/help/outlook-web/ai-reply-in-reply-box.webp) The reply waits in Outlook's reply box, next to Send and AI Reply, until you send it. *Numbers in the screenshot:* (1) Send; (2) AI Reply To answer only the sender, click Outlook's **Reply** first, then click **AI Reply** next to **Send** in the reply box. ## Write a new email 1. In Outlook on the web, click **New mail**. 2. If you like, type the subject first: Jetwriter uses it. 3. Click **AI Reply**, next to **Send** at the top of the new message. 4. Describe the email in a few words, such as "Invite the team to Friday's review at 2pm", and press **Enter**. 5. Click **Insert**, check the email, add the recipients and send it from Outlook. ## What AI Reply reads AI Reply reads the email thread of the reply you're writing: the earlier messages, the subject, who the reply goes to, and your name. If Outlook hides the earlier messages in your reply, Jetwriter opens them to read them, so you may see them appear at the bottom of the reply box. It doesn't read the rest of your mailbox. ## If something goes wrong - **No AI Reply button:** check the address bar shows outlook.live.com, outlook.office.com, outlook.office365.com or outlook.cloud.microsoft, then reload the Outlook tab. That fixes it in most cases, especially right after you install or update Jetwriter.
