Margin: Read with Claude · Delancey Labs LLC

Margin support.

Email mick@delanceylabs.com and we’ll get back to you. It helps to include your device, its iOS, iPadOS or macOS version, the version of Margin (shown in the App Store), and what happened, step by step. If a particular article is the problem, include its link. Please don’t send passwords or API keys.

Margin runs on iPhone and iPad with iOS or iPadOS 18 or later, and on Macs with macOS 15 or later.

Subscriptions and restoring purchases

Margin is a monthly or yearly subscription with a one-week free trial, billed through the App Store. It includes every AI feature, with no API keys to set up. To change or cancel, open Settings › Subscription › Manage Subscription in Margin, or your Apple Account’s subscriptions.

If Margin asks you to subscribe again on a new device or after reinstalling, tap Restore Purchases (in Settings › Subscription, or on the subscribe screen) while signed in with the Apple Account you subscribed with.

Daily limits and extra credits

Each subscription has generous daily limits, which reset at midnight UTC; Settings › Subscription › Today’s usage shows where you are. If you reach one, you can wait for the reset or add a pack of extra credits. Credits never expire, are only used after a daily limit runs out, and work on every device that uses your subscription.

iCloud sync

Your library, conversations, highlights, images and videos sync between your iPhone, iPad and Mac through iCloud. Sign in to the same Apple Account on each device and make sure iCloud is on for Margin. New articles usually appear within a few minutes; pulling down to refresh in the library (or pressing ⌘R on a Mac) checks for anything new. If your iCloud storage is full, syncing stops until there’s space again.

Narration audio and the library search index are made on each device separately, so a new device may take a little while to prepare them.

The Safari extension on Mac

  1. In Safari, open Settings › Extensions and turn on Margin. (Margin’s own Settings › Safari › Turn On in Safari… takes you there.)
  2. Click the Margin button in Safari’s toolbar, or press ⌥⇧M, to save the page you’re reading, or the post or thread you have open on X.
  3. Right-click any link (on X, a post’s timestamp) and choose Save Link to Margin to save it without opening it.

On iPhone and iPad, use the Share button in Safari or any other app and choose Margin. You can also paste a link with the + button.

Connecting X bookmarks

Margin imports your X bookmarks, including whole threads and X Articles, through your own X developer app, so the connection is yours alone. X bills bookmark reads to your developer account.

  1. Go to developer.x.com, sign in, and create a Project and an App.
  2. In the App’s User authentication settings, choose Native App with Read permissions. This uses OAuth 2.0 with PKCE, so there’s no client secret.
  3. Set the Callback URI to margin://x-oauth, and enter any website URL.
  4. Copy the OAuth 2.0 Client ID (not the API key), paste it in Margin under Settings › X Bookmarks, and choose Connect X Account.
  5. Add API credits to your developer account.

Margin checks for new bookmarks when you open or refresh it, at most every 30 minutes, and only imports bookmarks newer than the last import. Import New Bookmarks fetches them right away. Your X connection is kept in iCloud Keychain, so your other devices are connected too. Choose Disconnect to stop.

Deleting your data

Delete an article in the library (swipe it, or right-click on a Mac) to remove it, with its conversations and media, from all your devices. To remove everything, delete Margin’s data in your iCloud storage settings and then delete the app. You can export your library first with Export Library in Margin’s Settings. The privacy policy has the details, including how to remove what our server keeps.
