Honest comparison
Spent Agent vs Splitwise
The short version: Splitwise is a mature, well-designed app where you type each expense into a form and it tracks who owes whom across many groups; Spent Agent is a chat-first tracker where you text what you spent to an AI assistant and it keeps one shared ledger for the whole house. Both help roommates stop losing track of shared costs. The real difference is the input method — app forms versus natural language — and whether anyone has to act as the treasurer. This page lays out where each one is stronger so you can pick the right fit.

Where Splitwise is strong
Splitwise is the established name in bill-splitting for good reason. It has polished native apps on iOS and Android, years of refinement, and detailed IOU tracking that works across many separate groups at once — your apartment, a trip with friends, a group dinner. If you want a mature mobile app with a large existing user base and granular control over every balance, Splitwise is a safe, proven choice.
Where Spent Agent is different
Spent Agent's difference is natural-language logging through an AI assistant and one shared ledger for the whole place. Instead of opening an app and filling in a form for each expense, you text the assistant the way you would text a roommate — "paid $240 for the electric," "got $100 of groceries for the house" — and it records the entry on a single running total everyone shares. Because there is one ledger rather than a web of IOUs, no one has to be the treasurer, and at month end you text "settle up" to get who-pays-whom in the fewest transfers. It also never connects to your bank: you enter what the house spent, and it does the math.
Who each one is for
Spent Agent is for you if…
- You would rather text an expense in plain language than fill in an app form.
- You want one shared ledger for the house, not a tangle of person-to-person IOUs.
- You are tired of being, or appointing, the treasurer.
- You value that it never connects to your bank.
Splitwise is for you if…
- You want a mature, highly polished native mobile app.
- You juggle many separate groups (roommates, trips, events) at once.
- You prefer detailed, manual control over every individual balance.
- You are already using it and your whole group is set up there.
The bottom line
Both tools solve the same core problem — roommates losing track of shared costs — and either will serve most house-shares well. Choose Splitwise for a proven mobile app and cross-group IOU tracking. Choose Spent Agent if you would rather log expenses by chatting with an AI, keep one shared ledger, and let the system be the treasurer so no one else has to.

Frequently asked questions
What is the difference between Spent Agent and Splitwise?
The core difference is how you log expenses and how the house tracks them. With Splitwise you open an app and type each expense into a form, and it tracks a web of IOUs between people. With Spent Agent you text what you spent to an AI assistant in plain language, and it keeps one shared ledger for the whole place. Splitwise is a mature, polished app with iOS and Android versions; Spent Agent is a chat-first, AI-driven tracker focused on removing the data-entry and treasurer burden.
Is Spent Agent free like Splitwise?
Spent Agent is free during its beta. Splitwise has a free tier and a paid Pro subscription that unlocks receipt scanning, currency conversion, and higher limits. Both let a roommate group track shared expenses without paying, but some Splitwise conveniences sit behind its Pro plan.
Does Splitwise connect to your bank account?
Splitwise does not debit your bank to settle balances by default; it tracks who owes whom and can hand off to a payment provider to actually move money. Spent Agent never connects to your bank at all — you enter what the house spent, and it does the accounting. Neither tool needs your bank login to track expenses.
Can you log an expense by sending a photo of a receipt?
Splitwise offers receipt scanning on its paid Pro plan. Spent Agent is built around natural-language chat — you tell the assistant what you spent — and you can send a photo of a receipt for it to read. If snapping receipts is central to how you track, check the current state of each tool, since receipt features change over time.
Which is better for roommates, Spent Agent or Splitwise?
Splitwise is better if you want an established mobile app with years of polish and detailed IOU tracking across many separate groups. Spent Agent is better if you want to log expenses by texting an AI in plain language, keep one shared ledger for the whole house instead of a web of IOUs, and avoid anyone having to be the treasurer. Many roommates will be happy with either; the choice comes down to whether you prefer app forms or chat.
