# Outlook Add-in
> Use Sensbot AI directly inside Microsoft Outlook as a side panel — for classic desktop Outlook, Outlook on the web, and the new Outlook for Windows
# Sensbot AI – Outlook Add-in
The Sensbot Outlook Add-in brings AI-powered email assistance directly into Microsoft Outlook. Without switching apps or copying email content, you get instant AI-generated reply drafts, email analysis, and decision support — all inside a side panel next to your inbox.
## Two versions
There are two versions of the add-in, depending on how you use Outlook. On Windows there are also **two different Outlook desktop apps** — the older **Outlook (classic)** and the **new Outlook** — each of which uses a different version of the add-in:
The new Outlook is a rebuilt app (based on the same technology as Outlook on the web), while classic Outlook is the long-standing desktop program. The quickest way to tell which one you're in: look at the **top-right corner of the Outlook window** — if you see a **New Outlook** toggle, you're in the new Outlook; if there's none, you're in classic Outlook.
### Classic Outlook (desktop)
The desktop add-in works with the classic Microsoft Outlook application on Windows. It integrates as a task pane in the Outlook ribbon and is compatible not only with Microsoft 365 email accounts but also with **any other email provider** you have connected to Outlook — including Gmail, IMAP/SMTP, and others.
This version is available now. See [Installation](/customization/email-assistant/outlook-addin/installation) to get started.
### Outlook on the web **and the new Outlook for Windows**
The web add-in works in Outlook on the web for both Microsoft 365 (work/business) and personal Outlook.com accounts. It appears in the same Outlook add-ins toolbar and shows the identical Sensbot AI panel.
The web add-in works **only with Microsoft mailboxes** (Microsoft 365 or Outlook.com). To use Sensbot with a **Gmail, IMAP, or POP** account inside Outlook, use the [classic desktop add-in](/customization/email-assistant/outlook-addin/installation) instead — it works with any provider connected to classic Outlook.
The **new Outlook for Windows** (the new desktop app that replaces classic Outlook) uses the **same web add-in and the exact same install and usage procedure** as Outlook on the web. If you use the new Outlook app, follow the web pages — not the classic desktop installer.
Business accounts are deployed centrally by an administrator; personal accounts install it themselves. See [Web installation](/customization/email-assistant/outlook-addin/web-installation) to get started.
## How it works
Once installed, the add-in adds a **Sensbot AI** button to the Outlook ribbon. Clicking it opens a side panel. When you select an email, the panel automatically loads that message and either shows a previously generated response or lets you generate a new one with a single click.
The panel is identical in both versions — the same AI analysis, response tabs, and refinement tools are available whether you use the desktop app or the web client.
For full details on working with the panel, see [Usage](/customization/email-assistant/outlook-addin/usage).
