The peace of mind of knowing exactly what you have.
No more guessing, no spreadsheets, no arguing about who paid what. Every currency you share, fiat or crypto, lands in one clear picture — and your AI assistant can read it, answer from it and keep it up to date for you.
Free plan. No card required.
Balances per currency, not a blended guess.
Every account keeps its own currency — see your euros, dollars and crypto exactly as they are, not blended into one misleading total.

Read the ledger
That is €44.20 more than in July, which came to €368.10.
Connected in a minute.
Paste one address into Claude or ChatGPT and sign in. No API keys, nothing to install.
It acts as you.
It sees the teams you belong to and can do what your role allows there, nothing more.
Every change on the record.
What it writes shows up in the activity log, marked as the assistant's work.
Disconnect it any time.
Cut its access from your account settings and it stops at once.
Included in every plan, Free too. Each plan's limits apply.
Built around how your money really works.
Not a spreadsheet with a nicer skin. Accounts that speak several currencies, a ledger everyone writes to, and every rate kept exactly as it was.
Accounts that hold more than one currency.
Bank, cash or crypto — each account holds every currency you enable on it side by side, with its own balance for each one.
One ledger, everyone writing to it.
Invite whoever shares money with you by email. Everyone writes to the same ledger and sees who recorded what.
A short list of categories, plus tags.
Every movement is filed under one category you never had to design, and tagged the way you actually think about it: rent, the trip, the dog.
The rate, saved exactly as it was.
Every transaction stores the exchange rate of the day it happened, synced daily. Months later it still reads true.
Find anything in seconds.
Filter by account, currency, tag or date — or just search. The list keeps loading as you scroll.
Delete without breaking anything.
Remove a transaction and the balance goes back exactly where it was. No manual fixing afterwards.
Budgets that follow the month. On Pro.
Set a monthly amount per category or tag, in each currency, and watch what is left as the month goes.
Three steps, and the first one takes a minute.
There is nothing to set up, no chart of accounts to learn and no categories to design: the short list comes with the ledger. You write down money as it moves and the ledger keeps the rest.
01
Name the places your money lives.
The bank, the cash at home, the crypto wallet. Turn on the currencies each one holds and it keeps a balance for every one of them.
02
Write down what came in and what went out.
Amount first, then the account. The date, the note and the tags are one tap away, and the rate of that day is saved with it.
03
Look back together.
At the end of the month you see what entered, what left, and where it went by tag, in each currency on its own.
Free for one ledger. Pro when you outgrow it.
Every currency, every movement and every tag is free and unlimited on both plans. Pro is for when you need more accounts, more people or your whole history.
