Scans your accounts-payable export in the browser for duplicate vendor payments, and the file never leaves the tab. Built for finance teams doing AP audits, not general spreadsheet work.

Data stays with youCan export my data
What to know
How it works
Scans an AP export (CSV/Excel) in the browser for suspected duplicate vendor payments — same invoice paid twice, invoice number variants, duplicate payment references, unapplied credits — and produces a CFO-ready HTML report plus Excel export.
What's different
Runs entirely in the browser under CSP that blocks outbound requests, so the file never leaves the tab.
Best for
Finance teams running accounts-payable audits.
Watch out
The reported result (found $38,125 of planted duplicates, 5/5, with zero false alarms) comes from a blind test the vendor ran itself, not an independent audit.

Turns bank statement PDFs into categorized spending, a cash-flow forecast and visual breakdowns, processed on your device, without ever linking to your actual bank account.

FreeData stays with youCan export my data
What to know
How it works
Users upload bank or credit card statement PDFs, and the app categorizes transactions, generates a spending narrative, visualizes cash flow with a Sankey diagram, and runs a 30-day cash flow forecast, all processed locally on the device.
What's different
Never connects to your bank account or requires bank logins — works entirely from uploaded statement PDFs, processed on-device.
Best for
People who want spending insights and forecasts from their bank statements without linking accounts, including those who want raw CSV/Excel exports.
Watch out
Requires manually uploading statement PDFs rather than live bank data, so it's only as current as the last statement uploaded.
