Margin's slim day timeline docked to the edge of the screen, showing the whole day at a glance.

Overview

Margin is a day planner for the Mac menu bar that turns plain sentences into real reminders and calendar events, for people who would rather type a thought than fill in a form. It starts with one keystroke. Press Option+Space, type a plain sentence in English or Arabic, and it becomes an Apple Reminder or a Calendar event, however you phrase the time. "Lunch tomorrow 12 to 1" just works.

The other half is a slim day timeline docked to the edge of your screen, with a live now line and a working-hours band, so the shape of the day is always in view. Ask it to find a free slot, drag a block to reschedule with a precision magnifier, finish a meeting early to reclaim the time, plan around a colleague's shared calendar, and send items to any list by typing an at sign.

Everything runs on Apple's own EventKit, syncing two ways with Apple Reminders and Calendar, with no account. An optional assistant, Apple Intelligence on your Mac or your own OpenAI, Anthropic, or Gemini key, fills in only the date and time and never rewrites your words. Margin is on the Mac App Store, and available as a direct purchase: a Developer ID notarized download with built-in automatic updates. It is also on iPhone, iPad and Apple Watch, and a focus timer started on the Mac follows you there.

Privacy

Your data stays on your device

Margin is local-first. Your reminders and events live on your Mac, in your own Apple Reminders and Calendar accounts through Apple's EventKit. There is no Margin account, no analytics, and no tracking. The only time anything leaves your device is if you turn on the optional assistant with your own API key; then the sentence you typed goes to the endpoint you picked, with the key kept in your Keychain. With the assistant off, which is the default, Margin makes no network connections at all.
