AI Bill Splitting

Simply take a photo of any receipt. Lightsplit's AI instantly scans and accurately identifies individual items, their prices, and quantities. It then allows you to assign these items to specific people in your group for a perfectly itemized and fair split, all in seconds. This removes manual data entry and calculation errors completely.

Simplify Debts

Lightsplit doesn't just track who owes what; it intelligently optimizes the settlement process. The system automatically calculates and suggests the minimum number of payments required to clear all balances within the group. This reduces transaction fees and complexity, getting everyone settled faster.

Organize by Group

Create dedicated groups for different circles and activities. Keep your vacation expenses with friends completely separate from your shared household bills with roommates or office coffee fund. This organized group management ensures clarity and prevents financial details from getting mixed up.

Track Balances Easily

Every expense updates the group's balances in real time. An intuitive dashboard provides an immediate, clear overview of all debts and credits. You can see at a glance who is owed money and who needs to pay, ensuring complete transparency and eliminating awkward conversations.

Multiple Currency Support

Perfect for international travel or groups with members using different currencies. Add expenses in any currency, and Lightsplit handles the conversion using up-to-date exchange rates. Everyone can see balances in their preferred currency, making global expense sharing straightforward.

Custom Get Paid Options

Add your preferred payment methods for getting paid back, such as PayPal, bank transfer, or local apps. You control how you receive money without having to share sensitive banking details with everyone in the group each time a settlement is needed.

Use Cases

CD Calculator

Comparing Bank CD Offers

Use the calculator to input terms from different banks—like Chase, Wells Fargo, or Navy Federal—to instantly compare which CD offer will yield the highest return. This allows for an apples-to-apples comparison before you open an account.

Planning for Specific Financial Goals

Project how much your savings will grow in a CD to meet a future goal, such as a down payment, vacation fund, or major purchase. Adjust the initial deposit, term, and rate to see various scenarios and create a solid savings plan.

Understanding Compounding Impact

See the tangible difference that compounding frequency makes on your total interest. Switch between daily, monthly, and annual compounding with the same APY to visualize how more frequent compounding accelerates growth.

Evaluating Early Withdrawal Scenarios

Model the potential penalty impact of cashing out a CD early. By calculating the projected maturity value, you can better assess if accessing your funds before the term ends is financially worthwhile despite penalties.

Social Dining and Events

Project and Office Expenses

Useful for work teams, committees, or small offices managing shared budgets for supplies, client meals, or team activities. A dedicated group keeps all project-related expenses organized and accountable, simplifying reimbursement and budget tracking.
