Private beta · UK

Know every penny. Find the ones you're missing.

Sarah connects to your accounts, works out your net worth, and goes looking for money: the 0% deal about to end, the mortgage fix, the bill that's quietly gone up. Where there's a pound figure, you get the maths behind it.

Show the maths

Every pound comes with its working

Sarah never just says “you could save money”. Each move shows the sum behind its figure, using your own balances and bills, and names the market figure it compared against.

Line-by-line maths you can check yourself
Every comparison names its source and date, such as Moneyfacts, Ofgem or Ofcom
Where the data is uncertain, Sarah uses the figure that understates the saving

What Sarah does

A money-saving engine, not a budgeting app

Net worth, always current

Bank accounts and cards through Open Banking, plus your home, mortgage, pensions and investments. One number, updated every time you open the app.

Money moves, in pounds

Idle cash, 0% deals ending, mortgage fixes, bills above typical, subscriptions you forgot. With the figures and the maths shown.

Deadlines you won't miss

The remortgage window, the 0% cliff, the insurance auto-renewal. Sarah flags them months ahead, not the week after.

Every transaction, searchable

A year of spending across all your accounts. Search, filter by category, account, size or direction, and see where it really goes.

Read-only and revocable

Sarah sees, never moves, your money. Connections go through Finexer, an FCA-authorised provider, and you can cut them off from your bank at any time.

Yours, not a product

No selling your data, no affiliate-steered rankings. When Sarah suggests a switch it's because the maths says so.

Connect

Link your banks and cards through Finexer. Add your home, mortgage, pensions and investments in a minute.

Sarah goes to work

A year of transactions is categorised, recurring bills are spotted, and every rule in the engine runs against your money.

Act on the moves

Each one is explained, with a pound figure where we can show one, and sorted by urgency. Do it, or tell Sarah it's not for you.

Regulated connections

Bank access runs through Finexer, authorised and regulated by the FCA. Sarah never sees your bank login.

Read-only, always

Sarah can look, never touch. No payments, no transfers, no changes to your accounts.

Your data, your call

Delete your account and everything goes with it. We don't sell data and we don't rank offers by commission.
