Share a Grocery List

Shared grocery lists eliminate communication gaps and prevent duplicate purchases. Instead of texting "Did you get milk?" or calling from the store, everyone sees updates in real-time.

ListAIse synchronizes shared-list changes without a manual refresh. Updates normally appear on the other devices within 1 to 2 seconds.

Sharing a list takes less than 30 seconds. Follow these steps:

2

Tap the Share Icon

Look for the share icon (usually in the top right corner or in the three-dot menu). It looks like three dots connected by lines or a standard "share" icon.

Tapping this opens the sharing interface.

Enter Collaborator Information

You can invite collaborators in two ways:

• By Email: Enter their email address (they'll receive an invitation email)
• By User ID: If they're already a ListAIse user, enter their User ID for instant sharing

Finding User IDs

Users can find their User ID in Settings → Profile → User ID. It's a unique identifier that makes sharing faster than email invitations.

Collaborator Accepts & Syncs

When the collaborator accepts the invitation:

1. The shared list appears in their Lists tab instantly
2. They see all existing items immediately
3. Changes sync in real-time from that moment forward
4. They receive a welcome notification

Acceptance Required

The list won't appear for the collaborator until they explicitly accept the invitation. This prevents unwanted shared lists.

Viewing Current Collaborators

To see who has access to a list:

1. Open the shared list
2. Tap the share icon or go to List Settings
3. View the "Collaborators" section

You'll see:

• Collaborator names and email addresses
• Permission level (Editor or Viewer)
• Last active time (when they last viewed/edited)
• Pending invitations (not yet accepted)

Changing Permissions

List owners can change collaborator permissions anytime:

1. Open List Settings → Collaborators
2. Tap on the collaborator you want to modify
3. Select new permission level (Editor ↔ Viewer)
4. Changes apply immediately

Removing Collaborators

To remove someone's access:

1. Open List Settings → Collaborators
2. Tap on the collaborator you want to remove
3. Select "Remove Access"
4. Confirm removal

The list will disappear from their account immediately. They'll receive a notification that access was revoked.

If you're a collaborator (not the owner) and want to leave a shared list:

1. Open the shared list
2. Go to List Settings
3. Scroll down and tap "Leave List"
4. Confirm you want to leave

The list will disappear from your account. The owner will be notified that you left.

Live Presence Indicators

See who's currently viewing or editing the list with presence indicators. Active collaborators show a colored dot next to their avatar.

Push Notifications

Stay informed with smart notifications (configurable in Settings):

• New items added: Get notified when collaborators add items
• Items checked off: See shopping progress in real-time
• List updates: Name changes, budget modifications, etc.
• New collaborators: When someone new joins the list

Conflict Resolution

If two people edit the same item at nearly the same time, the latest synchronized edit may replace the earlier value. Check the item again if a collaborator was changing it with you.

When you share a grocery list generated from a meal plan, collaborators can use its meal-aware views and assignments.

Shared lists use the following access and storage controls:

• Invitation-only: Lists can only be accessed by explicitly invited users
• Encrypted transmission: All data is encrypted in transit
• Secure storage: Data encrypted at rest in the cloud
• Permission controls: Fine-grained Editor/Viewer permissions
• Revocable access: Remove collaborators anytime instantly
• No public sharing: Lists are never publicly accessible or searchable
