File every email in seconds
AI-powered folder suggestions for Outlook. No rules, no configuration.
Folder Suggest uses on-device AI to instantly suggest the right Outlook folder for each email. No rules to set up, no cloud processing.
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.
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.
