How Hark compares with Gemini in Gmail
Google builds Gemini into Gmail for eligible Google accounts and plans. Hark is an independent alternative that works with any Gmail account in Chrome, adds an agent that can act on other websites, and keeps a Tracker of what your emails ask of you. If you live in Google’s ecosystem and already pay for Google AI, Gemini’s deep integration is a strength; if you want one assistant for Gmail, Outlook and the rest of the web, Hark is built for that.

Privacy by architecture
Hark does not use the Gmail API. It cannot list, search or read your mailbox; it only sees the message displayed in your tab when you press a button. Hark is not affiliated with or endorsed by Google; Gmail is a trademark of Google LLC.

Open a message in Gmail
In Chrome, at mail.google.com.

Press Alt+Shift+H and tap “Summarize this email”.

Does Hark need permission to access my Gmail account?
