How it works

  1. Answer

    A few simple questions, one at a time. Stop and pick it back up whenever you like.

  2. We work out a fair split

    Fifty-fifty, proportional to income, or the same personal spending money each: you decide together. On your own? We just build your budget.

  3. Early access

    Your plan

    The automatic transfers to set up, one amount to watch each week, and a checklist of what to put in place.

What you get

A clear plan, designed so you don’t have to log every purchase.

  • Your weekly amount: the one number to watch.
  • Your automatic transfers, with the amount and date for each paycheque.
  • A « do this weekend » checklist to set it all up.
  • Calendar reminders, no email needed.

We never connect to your bank: you set up the transfers yourself.

Example Coussinet plan for a couple: the weekly amount, then the table of automatic transfers for each paycheque.Example Coussinet plan for a couple: the weekly amount, then the table of automatic transfers for each paycheque.

The interview, your budget preview and the encrypted save are free. The full plan will be a paid feature. For now, it’s in early access: it opens with an access code.

Got an access code? You’ll enter it at the end of the interview.

Your budget stays private

  • No account, no email, and no need for your real name.
  • Your budget is encrypted in your browser before it is saved.
  • Only your code opens it. Keep it safe: we can’t recover it for you.
