OVERVIEW
About Shortwave
Shortwave is an email app that runs on top of Gmail and Google Workspace. Its AI groups newsletters and updates into bundles, applies filters you write in plain English, and turns an email into a to-do in one click. It can draft replies in your writing style, summarise long threads and search your mail from a plain description. The assistant can also check your Google Calendar, create events and write scheduling emails.
The practical use is a faster daily inbox pass: clear the low-value mail, see what needs you and start from a drafted reply. Shortwave suggests replies, but you decide what to send. When you ask, the assistant can create calendar events and send invites, so check those before they go out. It needs a Gmail or Google Workspace account; Microsoft 365 and Exchange mailboxes are not supported. AI use comes from a daily quota that grows with the plan, and Shortwave says customer data is not used to train third-party models.
