Setting up your account

Marginborn opens with a clean slate: no passwords to invent, no waitlist to wait on. The first time you open Marginborn — in a browser at app.braird.app, or in the Android app — you can be capturing notes inside three minutes.

Step 1: Sign up

On the opening screen, pick either Continue with Google or Sign up with email.

• Google. One redirect, you're back signed in. No password, no email round trip.
• Email. Enter your address — Marginborn sends a six-digit code (or a magic link, depending on your device). Type the code in the same screen and you're in.

TIP

If you already have an account, the same buttons work for signing back in. The OTP endpoint figures out whether you're new or returning automatically.

Step 2: Verify your email

If you signed up by email, the code in your inbox is also your verification step. Email-verified accounts have full access immediately; until that's confirmed, sign-in attempts that don't include the verified code will be rejected.

Inbox not arriving?

Check spam, then make sure you used the exact same address you signed up with. The send-rate is generous but not unlimited — wait 30 seconds between resends.

Step 3: Set up encryption

Marginborn encrypts the text of your notes end-to-end. Your device handles encryption with a passkey — a piece of cryptographic material your phone or laptop holds on your behalf, unlocked by Face ID, Touch ID, Windows Hello, or your PIN.

When you first sign in, Marginborn asks you to set up encryption. This step is required: every note you save is encrypted before it syncs. Tap Set up encryption and accept the system prompt to create the passkey. From then on, unlocking your notes is as quick as glancing at your phone.

What you need

A browser and passkey provider that support passkey encryption: Chrome, Edge or Safari with Google Password Manager, iCloud Keychain or Windows Hello. If Marginborn says this browser can't set up encryption, open it in one of those browsers, or use the Android app.

Adding a second device

You can add more devices later from Settings → Linked devices. Marginborn will issue a six-digit transfer code from your working device that your new device types in to enrol its own passkey — the master key never leaves your control.

Step 4: Make your first capture

You're done with setup. Open the camera from the Home screen and walk through Capture your first page to capture, transcribe, and tag your first note.

Reader plan

You get 50 managed-AI calls per month on the Reader plan — enough to comfortably index a couple of dozen pages. Heavier indexing schedules can upgrade to Practitioner from the Settings page when you're ready.
