Your day, announced before it arrives. Posthorn reads your email, calendar, messages, and chat — and surfaces the few things that actually need your attention.
Your data never leaves your machine in unencrypted form. Memory, raw email, message contents — all stay on your Mac. We don't have servers that see them.
Setup takes about 10 minutes. Five short steps. We'll never ask you to remember anything you've already told us.
Posthorn reads iMessage + Apple Notes locally, and uses Messages to text you reminders. Click each button, then come back here.
Posthorn uses a large language model to compose your briefings and parse your replies. Pick where it runs.
You can change this later in Settings.
Each one opens a sign-in flow. You can add more or remove any later. Skip what doesn't apply.
I'll ask 5 or 6 questions. This becomes the memory I use to interpret everything else. Skip anything you don't want to answer — we can come back to it.
