Gmail
Premium OAuth CommunicationEmail drafted in your voice, sent on your say-so.
Tell Halo "email Mario about the pricing change" and it writes the message in your voice, shows it to you, and only sends when you confirm. The draft is written and reviewed on your Mac; Gmail is only involved at the moment of sending.
Halo asks Google for the narrowest permission that makes this work: sending only. It can't read your inbox with this connection, a deliberately small footprint.
Premium
A paid capability, part of a Halo plan. The free Mac app stays fully featured on its own.

What Halo does with it
With a Halo plan
- Drafts email in your voice, using what you're working on as context
- Shows you every draft and sends only when you confirm; nothing goes out on its own
- Uses a send-only permission: Halo can't read your inbox
How it connects
You authorize. Your Mac holds the key.
- 01
Set up Halo's own line
A quick one-time setup gives Halo a dedicated Apple ID, a private line that is just for talking to it. You make it once, the way you would any Apple ID.
- 02
Text it from your iPhone
Message that line from your iPhone like you would text a friend. Your Mac, signed in to the same line, receives it.
- 03
Your Mac answers
Halo reads the text on your Mac, thinks on your Mac, and texts you back. The whole exchange rides Apple's end-to-end-encrypted iMessage.
What stays private
Your Google key is stored in the macOS Keychain and refreshed from your Mac. The permission is send-only, so Halo cannot read your mail, and your drafts are written and reviewed on-device before anything goes out.
