Hemmingway-one is our own model. It writes like a person, not a machine, and it is built for talking to people and for writing beautifully. In our tests it sounds more human than any model we put next to it, at a fraction of their size.
Hemmingway reads your mail and chats, writes the replies the way you would, and asks before anything is sent.
It learns how you write from your own messages, and writes replies you would send.
Nothing goes out in your name until you say so.
Gmail, Outlook, iCloud Mail, WhatsApp, Slack and Teams.
On the Mac, it handles what it can on its own. On Plus, Pro and Max.
Your chats, memory and settings follow you between the app and the browser.
Download it, or open it in your browser. Same account, same Hemmingway.
