Assistants rename their menus often, and custom connectors may depend on your plan. If a step looks different, look for connectors or apps in your assistant’s settings.
What your assistant can do
Once you allow it, your assistant acts as you: it can see your groups, balances and expenses, add, edit or delete expenses, record a payment and create groups. Every change shows in the app, and can be undone.
Try asking
“What do I owe in the Lisbon trip?”
“Add 60 € of groceries, I paid, split with Sam.”
“Create a group for the ski weekend with Léa, Sam and Noah.”
You stay in control
