Writing
AI reply drafts in your own voice.
Three ready-to-send replies for any message. You pick, tweak, or ignore.
Halo drafts replies for you, in your own voice, for any message on your Mac. Press the reply shortcut and three ready-to-send options appear, drawn from the message you're answering. Pick one with a number key, tweak it, or ignore them all. You always read it before anything sends.
How it works
Three ways it earns the shortcut.
Three options, instantly
For any message, Halo offers three replies at once so you can choose a direction rather than write from a blank field.
Written like you
Drafts are shaped by how you actually write and your saved styles, so they sound like you and not a template.
You always send
Pick one, edit it, or dismiss them. Nothing is sent until you say so, and Halo never messages someone new on its own.
Private by design.
Reply drafts are generated on your Mac from the message on your screen. Nothing is uploaded, and Halo never sends anything without your confirmation.
FAQ
Questions, answered.
Which apps does it draft replies for?
Any message you're looking at on your Mac, including Mail, Slack, and other chat apps. Halo reads the thread locally to write in context.
Do the replies send automatically?
No. Halo offers drafts; you choose whether to send, and you can always edit first.
Do they sound like me?
Yes. Drafts follow how you write and your saved styles, so they read in your voice.
