Getting Started with Meridian

Creating Your Account

There are two ways to create a Meridian account:

Email and Password

1. Go to Sign Up or open the Meridian app
2. Enter your email address
3. Choose a password (minimum 8 characters)
4. You’re in

Sign In with Google or Microsoft

1. Click the Google or Microsoft button on the sign-in screen
2. Authorize Meridian in the popup window
3. Your account is created automatically and your first connection is set up at the same time

If you already have an account, the same flow will sign you in instead.

Setting Up Your Profile

After creating your account, you can update your profile in Settings:

• First name
• Last name

Your email address is tied to your account and can’t be changed.

Connecting Your First Account

Meridian becomes useful the moment you connect an external account. Head to Connections in the sidebar and link your Google or Microsoft account. See Connecting Your Accounts for the full guide.

The First Sync

When you connect an account, Meridian runs an initial sync to pull in your existing data. Depending on how much email and how many calendar events you have, this can take a few minutes. After that, syncing happens automatically in the background.

On-Device AI Setup

Meridian downloads a recommended AI model that runs locally on your Mac. This happens in the background and does not block the rest of the app. Model size depends on your hardware and selection.

Note: Meridian requires Apple Silicon (M1 or newer) and macOS 15 or later.
