Free, and it runs in your browser

219 tools for everyday work

Bookkeeping, VAT returns, payroll, invoices, PDFs, images and school timetables — and 1,048 unit converters as well. It all runs inside this browser tab: the file you open is read on your own device and never uploaded. The 49 AI tools are the exception, and every one of them says so before you send anything.

How this works

  • Nothing you open is uploaded. A tool is JavaScript running in this tab: it reads the file you pick off your own disk and writes the result back there, so a client’s ledger or a class list never leaves the machine. The 49 AI tools are the exception, and each one shows you exactly what will be sent before it goes.
  • No account for the browser tools. 1,218 of the 1,267 ask for nothing at all — no sign-up, no email address, no trial with a date on it.
  • It keeps working with the network off, and it installs. Each tool is one page, and your browser keeps it once you have opened it — so it still runs on a train or a building site, and it can be added to a home screen like an app.
  • Where a rule can change, the page says when it was last checked. 26 tools apply a tax rate, a threshold or a statutory formula. Each one prints the date a person last checked it and links to the gov.uk, CBIC or board page that settles it, rather than asking to be trusted indefinitely.

What it costs

  • Free. Runs in your browser. No account, no upload, no limit. That is 1,218 of the 1,267, and it stays that way: they cost us nothing to run.
  • Free to try. Needs an account. Ten AI calls a month free, more on a paid plan. That is the 49 AI tools, which cost us money every time somebody presses the button.
  • Nothing is premium-only. There is no tool you cannot reach without paying. A paid plan raises the monthly allowance on the AI tools, and that is all it buys.

Some of the bigger ones

Not three boxes and an answer. These read a file you already keep and hand back a set of books, a return, a month of payslips or a school year.

Bookkeeping: Trial Balance, P&L and Balance Sheet — Free OnlineBring a bank statement, a sales day book or a set of journals into a real double-entry ledger and get the trial balance, profit and loss, balance sheet, VAT or GST figures and every account’s ledger back. Charts of accounts for the UK and India. Runs in your browser — a client’s books are never uploaded.FreeVAT Return from a Spreadsheet (the nine boxes) — Free OnlineTurn a spreadsheet of sales and purchases into the nine boxes of a UK VAT return — standard accrual, cash accounting or the flat rate scheme — with every box opened up to show the rows behind it, and the sheet checked for net-plus-VAT that does not equal gross, duplicate invoice numbers and rows outside the period. It computes the figures; it does not file them. Runs entirely in your browser.FreeMonthly Payroll Run: Payslips, Bank File & Statutory Summary — Free OnlineDrop in a salary sheet and get the whole month's payroll: a payslip PDF for every employee in a zip, a combined PDF, the bank bulk-transfer CSV, and a register workbook with PF, ESI, professional tax and TDS summaries.

Runs in your browser; nothing is uploaded.FreeSchool Timetable Generator — Free OnlineGive it the subject allocation — class, subject, teacher, periods a week — and get a clash-free timetable: a grid for every class, a grid for every teacher, double periods kept together, teacher free days honoured, and a plain list of anything that would not fit. Runs in your browser; no staff names are uploaded.FreeBank Reconciliation — Free OnlineMatch a bank statement against the bank ledger from your books — Tally, Zoho, QuickBooks or a spreadsheet — and get the unmatched entries on each side, the matched pairs, and the closing balances explained.

The tool you need is not here

Then say so. Most of what is on this site exists because somebody had a job to do that nothing else did properly — a statement in the wrong format, a return that had to be typed out twice, a timetable done by hand every July. If that is you, describe it. You do not need an account, and there is nothing to sign up to.

One sentence is plenty. What the job is beats what the feature should be called.
It decides what gets built first: five people with the same job beats fifty with fifty.
