If you could talk to your finances, what would you ask?
Seffin is a personal finance workspace. Your money is laid out as paper cards on an open desk, and a desk agent sits on this page ready to answer anything. One real ledger underneath does the math.
Spreadsheets are free. Finance apps are sturdy. You shouldn't have to choose.
People bounce from sheets to apps and back, because apps wall them in and sheets make them do all the work. Seffin is built to end the round trip.
Sheets, ledgers, goals, and summaries are paper cards on an open desk. Lay them out the way you already think about your money. No template to fight, no screens in a fixed order.
Every amount posts to one master book, and every total is computed for you. All the freedom of a sheet, with nothing for a stray formula to break.
Anything you'd reach for a formula to do, you do with a plain sentence. If you can keep a list on paper, you can keep your books here.
Be at the desk first.
Seffin is opening soon, and invites go out in the order people joined. Leave your email to hold your spot.
