Take the helm of your money.
Drop in your bank and broker statements. Helmsman charts your net worth, keeps the business apart and gets your Self Assessment figures ready.
From a folder of CSVs to a clear view.
Five stops, in the order you make them the first time. After that, most months are just the first two.
- Export
Start with the files your bank already gives you.
Every bank and broker can export a CSV. Helmsman recognises Monzo, Revolut and Trading 212 from their columns. Any other bank you map once, and it remembers.

Let your AI go through the books.
Connect an assistant that supports MCP, such as Grok or Claude. Ask about your tax year and it reads your transactions, then flags the ones worth a second look.
Reads, never rewrites.
It sees your accounts, transactions and tax-year summary. It can't change an amount or a category, or delete anything.
Flags for you to check.
Each flag carries the assistant's reason. Review them on the Transactions page and clear one in a click.
Your key, your call.
One access token per assistant, shown once. Revoke it and that assistant is cut off straight away.
Free for early users.

Two household rows look like business costs. I've flagged them in Helmsman for you to check.
A prompt to check, not tax advice. Clear a flag in one click.
What Helmsman does that most money apps don't.
| Most money apps | Helmsman | |
|---|---|---|
| Side business | Personal spending only. The business needs its own bookkeeping software. | Household and business, side by side.Tag each row once. The sole-trader P&L follows, with invoices matched to their payments. |
| Your bank | A live connection to your accounts, held by a third party. | Never connects to your bank.You bring the CSV files, so there is no live link to revoke or to leak. |
| Investments | One balance for the whole account. | Every holding, priced.Shares and funds at a delayed daily price, crypto hourly, all in pounds. |
| Your AI | Your data stays inside their app, out of reach of your own assistant. | Bring your own AI.Connect an assistant over MCP to read the books and flag what to check at tax time. |
| Tax | A calendar year and generic categories. | Built for UK tax.The UK tax year, HMRC expense categories and a P&L laid out the way Self Assessment asks. |
Also on board.
The parts you reach for once the basics are in. Pick one to see it.
Holdings from your broker and anything you add by hand, with allocation by type and a flag when one position gets heavy.
One holding is above your 25% flag. A flag, not a recommendation.
What stays ashore.
Helmsman is built to know as little about you as it can while still being useful.
No ads, no selling.
Helmsman shows no adverts and never sells or shares your data. What you import is used for one thing: showing it back to you.
No tracking in the app.
No analytics, no advertising scripts, nothing reporting what you look at. The only outside calls fetch exchange rates and prices.
Everything in one file.
Download all your data as a single backup whenever you like, and bring it back into any Helmsman account.
Delete means gone.
Close your account and every transaction, rule and setting is deleted with it.
Questions.
Which banks and brokers work?
Monzo, Revolut and Trading 212 are recognised automatically. Any bank that exports a CSV works too: you match its columns once and Helmsman remembers them for next time.
Why CSV files instead of connecting my bank?
It keeps your bank login out of it entirely. Exporting a statement takes a minute, and you decide exactly what Helmsman sees.
Is my data private?
Your data is only ever visible to your own account, and to an AI assistant only if you connect one yourself. The app has no analytics or tracking. You can delete everything at any time, and download a backup whenever you like.
What can a connected AI assistant do?
Connect AI gives an assistant you choose its own access token. With it the assistant can read what you allow: your accounts, categories, transactions, tax-year summary, balances and net worth. It can also flag transactions for you to review, each with its reason. It cannot edit or delete anything. What it reads goes to that assistant's provider under their terms, and revoking the token cuts it off at once.
Does it work outside the UK?
Accounts in any currency are converted at the European Central Bank's daily rates, so the dashboard and portfolio work anywhere. The tax view follows the UK sole-trader P&L.
Is Helmsman financial advice?
No. It is a bookkeeping helper, not an accountant or an adviser. Its suggestions are simple rules you can read, and they are always labelled as not advice.
What does it cost?
Free for early users. Paid plan coming soon.
Can I get my data out?
Yes. Download a full backup, export transactions as CSV, or download the tax year as a spreadsheet.
Set your course.
Start with one CSV from last month. Add the rest when you are ready.
