Most AI email tools write an email. Hemmingway tries to write your email: the reply you would have sent if you had the time, in the way you write to that particular person.
How it works
The Hemmingway apps for Mac, Windows and Android have an Inbox. Connect your mail, and Hemmingway puts your mail and chats in one list, with what needs you first at the top.
- Open a message. Hemmingway reads the thread and drafts the reply.
- Read it. Change whatever you like, or ask for another go.
- Send it. Nothing goes out until you do.
It works with Gmail and Outlook, and the same Inbox holds WhatsApp, Slack and Teams, and iMessage on the Mac.
Why the drafts sound like you
Three things go into a draft besides the email itself.
- People. You can tell Hemmingway who someone is: your boss, a client, your sister. It then writes to them the way you would, in the language you use with them, with what it should keep in mind. They never see any of it.
- Memory. Hemmingway keeps a short list of things about you and your people. You can read every line, change it or delete it.
- The model. Hemmingway-1 was trained for exactly this kind of writing and tested against the largest models at it. On everyday messages and emails it came first in our tests. The numbers are here.
It also gives you the email and nothing else. No "Here's a draft you could send", no three options, no note at the end explaining the tone. What you see is what goes out.
Autopilot, if you want it
Autopilot is the part that answers on its own, and it is off until you switch it on. When it is on, it follows your rules: it answers people you know when they just need an answer, and holds everything else for you to look at.
Everything it does goes into Activity, newest first, with the reason it did it. Where a thing can be undone, there is an Undo next to it. Autopilot is in the Mac and Android apps, on the paid plans.
What it will not do
- Send in your name without asking, unless you have turned Autopilot on and the message fits your rules.
- Train on your mail. We do not train our models on your chats, memory or People. The privacy page says exactly what is kept.
- Decide things that cost you if they are wrong. It can sound sure and still be wrong. Money, legal and medical mail needs your eyes.
Getting started
Download the app, sign in, and connect your mail in Inbox. There is a free trial and no card is needed. If you only want to write an email now and then, the web version does that without connecting anything: paste in what you got, say what you want to say, and it writes the reply.
