With Claude you can create a custom check-splitting app

1. Start a new chat

Start by logging into Claude. Initiate a new chat and clearly state your intention in the prompt box: “I want to create a bill splitting app using Claude Artifacts” and hit enter. 

Claude will create a bill-splitting app that includes the bill amount, number of people, and tip percentage. 

2. Create an enhanced version

Next, ask Claude to “update the bill splitting app to include the ability to add specific expenses, track who paid, and split the bill among specific individuals.”

After prompting Claude, it will generate a new bill-splitting app to a more comprehensive one. Include the relevant information where directed. 

3. Process complex splits

When you encounter uneven splits or unique situations, describe them clearly to Claude and it’ll add it to your bill-splitting app.

For instance: “Add a $256 hotel stay. It’s split four ways, but only Kaycee, John and Nikki are part of the ongoing expense tracking. Alex paid their share directly, 10% less than what we paid.”

4. Keep inputting expenses

Keep adding new expenses to the artefact as needed, particularly for smaller expenses like parking, gas, or groceries.

You could say “New expense: $80.00 for 2.5 days of parking. Paid by John, split between Kaycee and Alex only.”

5. Make real-time adjustments

Take advantage of Claude’s flexibility to make any on-the-spot changes. In the prompt box, simply describe the adjustment. For example, “Subtract $10 from Nikki’s balance as she bought snacks for everyone.”, or “Add $5 to John’s total for the coffee he purchased yesterday.”

After each adjustment, ask Claude to recalculate and show updated balances.

6. Ask for updates on balances

Regularly check the current state of expenses. You can request updates from Claude in various ways, such as “Show me the current balance for each person”, “What’s the total spent so far, and how is it divided?”, or “Give me a breakdown of expenses by category (e.g., food, transportation, accommodation).”

7. Generate a final settlement

At the end of your trip or expense period, ask Claude to calculate the final settlement. You could ask Claude: “Please provide the final settlement calculations. Show who owes what to whom for the simplest resolution.”

Claude will analyze all expenses and balances, then suggest the most efficient way to settle all debts within the group.
