Astro and TypeScript, hosted on Vercel. Files are read in the browser inside a Web Worker, with Papa Parse for CSV and SheetJS for Excel, and every row is checked with Valibot. Tested with Vitest, fast-check and Playwright, including a run with the network switched off.
Each tool answers one money question from a file you can already export, like your Stripe payments or Xero invoices. You drop the file in and the answer comes with every sum written out, so you can check each figure against your own data. Everything runs in your browser. Your file is never uploaded, and there is no sign-up.
You get an answer in a minute without signing up or connecting your Stripe, Xero or ad accounts. Many alternatives need both before they show you anything. Each tool opens on sample data, so you can see what it does before you use your own file, and the file stays on your computer.
Owners and finance people at small and mid-sized businesses who want a straight answer from their own numbers. That includes bookkeepers and accountants who look after client books in Xero and QuickBooks, agencies and marketers who run Google and Meta ads, sellers on Square, Stripe, Shopify and Amazon, nonprofits on Givebutter, Airbnb hosts and YouTube creators.
otum.io is a software firm. Every week we read the questions business owners post on forums and support boards, and many come down to a sum their software won't do for them. In October 2026 we picked 30 of those questions and built a small free tool for each one. When a business wants the same answer on its own data every week, we build that for them.
None to name. The tools are free with no sign-up, and files never leave the visitor's browser, so we don't know who uses them. This is not a negative, but a positive, as privacy is a priority for us.
