Every amount is written twice — out of one place, into another — so it always adds up. What you owe counts against what you have. Fixes are added as new entries; nothing is erased.

How it works

You talk. Moneta keeps the books. You stay in charge of anything big.

Say what happened

Type it like a text message. Moneta works out the accounts, the currency, and the date.

Hands typing a text message on a smartphone

She writes it into your books

Every amount is written twice — out of one place, into another — so your numbers always add up.

You approve anything big

New accounts wait for your OK on a card. And old entries are never erased — fixes are written beside them.

A couple considering something together on a phone screen

You decide what your partner sees

One setting for your household. It applies everywhere — including what Moneta says in chat.

Yours only

Your money stays yours.

  • Your accounts and entries, in full detail
  • Shared accounts — the joint card, shared bills
  • Household totals or your partner's figures
Ask “what did we spend on food?” and Moneta answers from your side and the shared spending only.

Totals only

Together, without the details.

  • Household income and spending by category
  • Net worth, grouped by what you own
  • Who spent what
You learn “we spent 620.00 on groceries” — not “she spent 340.00 of it.”

All shared

One open picture.

  • Everything, with each of you named
  • Both partners' accounts and balances
  • Moneta records for whoever asks
Most couples start here — and you can change it any time.

You always see your own money in full. The setting only controls your partner's side.

Easy to use. Serious underneath.

The same bookkeeping method banks use — made as easy as texting.

Just say it

Type or talk like texting. No forms, no categories to pick.

Numbers you can trust

The chat understands you; plain code does the math. Nothing is guessed.

Made for two

One household for you and your partner — together, without sharing every purchase.

Privacy, your call

Share everything, just the totals, or nothing at all. Change it whenever you like.

Any currency

Spend in any currency. The day's exchange rate is saved with each entry.

A record that can't be edited

Fixes are added as new entries. Your history stays honest.

Beautiful on every screen

Four color themes for the whole app, on your laptop and your phone. Try one.

Earn in dollars, spend in euros, save in yen

Say the amount in the money you used. The exchange rate for that day is saved with the entry.

Your amount stays as you said it

What you said — and its currency — is written down exactly. Your home currency sits beside it, smaller.

You confirm the rate

If your bank used a different rate, you choose which one to keep. Either way, it's saved on the entry.

One home currency

Your reports and net worth stay in one currency, picked when you set up your household.

Why Moneta is different

Most money apps give you a job: typing everything in. Moneta gives you an accountant.

MonetaTypical budgeting apps
Your roleThe client. You say what happened. Moneta does the books.The clerk. You type everything in yourself.
EffortA sentence. Five seconds, spoken or typed.Forms and review queues, every week.
The mathReal double-entry, checked by code before anything is saved.Simple tallies that can hide debt.
PrivacyThree levels, enforced in the database — even for the AI's answers.Share everything, or nothing.

How the books stay honest

Chat is smart. The ledger is strict. That's the whole trick.

She answers like a person

Ask in your own words. She replies with numbers read straight from your books — not guesses.

You've spent 412.30 on dining this month, and 508.10 on groceries. Last month you were at 655.20 by this day.

Code does the math

The chat understands you, but the ledger is plain code. Nothing gets saved unless both sides balance.

Checking→Dining out−41.20 · 41.20
✓ Sum: zero. Checked before anything is saved.

Fixes, not cover-ups

A mistake gets a correcting entry, written beside the original. The full history stays — so you can always trust what's there.

Oct 3 · Petrol− USD 32.00
Oct 4 · Correction for Oct 3+ USD 9.00
The original stays on the record, next to the fix.

What we promise about the AI

  • Never writes an entry that doesn't balance
  • Never sees more than your privacy setting allows
  • Never touches another household's books
  • Never deletes — fixes go beside the original
  • Never makes up a number

Your data stays yours

No bank logins

We never ask for your bank login. Nothing to connect, nothing to break.

Households can't see each other

Your books are sealed off from everyone else's — enforced by the database itself.

A history no one can rewrite

Every change is recorded for good. No one can edit the past — not even us.

Privacy that includes Moneta

If your setting says your partner's side is hidden, it's hidden from her answers too.
