An alternative to Copilot for web mail
Microsoft offers Copilot in Outlook as part of its paid Copilot plans. Hark is a lightweight, independent option for people who use Outlook in the browser and want summaries and reply drafts without a Microsoft AI subscription — plus an agent and tracker that also work outside Outlook. See Hark vs Microsoft Copilot in Edge.
What it does not do
Hark works in the browser. It does not plug into the Outlook desktop apps, does not use Microsoft Graph and cannot search your mailbox. Hark is not affiliated with or endorsed by Microsoft; Outlook is a trademark of Microsoft Corporation.

Open a message in Outlook on the web
outlook.com or your Microsoft 365 web mail, in Chrome.
Open Hark
Press Alt+Shift+H and tap “Summarize this email”.
