Triage view: your recent inbox, each email with a suggested folder. Click the folder to file it, or the arrow to pick another. Undo is always one click away.

🔒 Nothing moves without you

Clear your inbox, not one email at a time

Folder Suggest works two ways, and you can switch between them with the toggle in the pane above. The classic view files the one message you're reading. Triage Mode shows your whole recent inbox as a list, each email already pre-sorted with a suggested folder, so you can clear it from one pane.

  • The folder is the button. Every email shows its suggested folder. Click it to file the email there, or the arrow beside it to pick another.
  • Change any suggestion. The arrow opens the top alternatives, a search across all your folders, and Create new folder.
  • Accept the strong matches in one go. Review the confident suggestions, untick any you want to keep in the inbox, and file the rest at once.
  • Reads like Outlook's own list. Unread mail, flags, attachments and date headings look the way they do in your inbox, and Find searches the whole folder.
  • Undo is always one click away after any move, including a bulk one. Ctrl+Z works too, and so does the rest of the keyboard.
  • Private by design. The AI runs on your device, so your emails never leave Microsoft's servers.

Triage Mode is the main experience in Outlook on the web, new Outlook for Windows, and Outlook for Mac. On classic Outlook for Windows, the classic single-email view stays the default and Triage is opt-in.

Folder Suggest is an Outlook add-in that uses on-device AI to recommend the right email folder for every message you read. Unlike Outlook Rules, which require you to pre-define conditions for each sender or subject, it reads the content of each email and matches it against messages already stored in your folders. No rules to create. No training required. It works immediately with whatever folder structure you already have.

The AI model runs entirely inside your browser, so no email content is ever sent to a server. On first use, a lightweight model (~20 MB) is downloaded once and cached locally. Every subsequent suggestion takes a second or two. Accept the top match with one click, or choose from up to seven ranked alternatives. An Undo button appears immediately.

See it in action

The video loads from YouTube only when you press play.

1

Open the pane

Your recent inbox loads as a list, each email already showing a suggested folder.

2

Review the suggestions

Use the arrow beside a folder to pick a different one, search all your folders, or create a new folder on the spot.

3

File with one click

Click the folder to file the email, or accept every strong match at once. Nothing moves until you say so, and undo is always one click away.

Your emails never leave your device

Folder Suggest processes everything locally using a small AI model that runs in your browser. Microsoft Graph is used only to read your folders. Nothing is stored on our servers.

Frequently asked questions

Is Folder Suggest free?
Yes — the free plan lets you file up to 5 emails per day, with every AI feature included and no account creation required. If you file more than that, Pro is €7.99/month (or €79/year) for unlimited moves. See pricing for the full comparison.
Does it read my emails?
Folder Suggest reads the sender, subject, and body of the email you're currently viewing, but only locally, inside your browser. No email content is ever sent to an external server. The AI model runs entirely on your device.
Which versions of Outlook does it support?
Folder Suggest works with Outlook on Windows, Mac, and web. For the smoothest experience, we recommend classic Outlook for Windows. It does not support Outlook mobile (iOS/Android).
What happens to my data?
Nothing leaves your device. The AI model runs in your browser, and folder similarity scores are cached locally in your browser's storage. Read the full privacy policy for details.
Can my IT admin deploy it to the whole organisation?
Yes. IT admins can deploy Folder Suggest through the Microsoft 365 Admin Center, either from the Marketplace catalogue or by uploading the manifest file. See the install guide for step-by-step instructions.
