FAQ

Questions finance teams ask about these tools

Are these finance tools really free?

Yes, every tool is free, with no signup, no email required, and no usage limit. They all run entirely in your browser, so nothing you paste is uploaded, stored, or logged. We build them because the people who find them useful tend to be the people who eventually need a financial analyst that works the same way.

Which tool should I use first?

If you are mid-task, start with the paste-and-go group: the reconciler, the cohort builder, and the P&L bridge each replace an analysis that takes 20 minutes or more to assemble by hand. If you are preparing for a board meeting, start with Board Question Prep.

Is it safe to paste real financial data?

The tools are client-side only: the parsing and calculation happen in your browser and no request carries your data anywhere. That said, follow your own organisation's policy on where financial extracts may be opened, the same way you would for any web tool.

Do these replace a financial analyst?

No, and a tool that claimed otherwise would be lying to you. Each one does a single well-defined job. The work that actually consumes a finance team: investigating why a number moved, joining data across systems, and answering the follow-up question: needs context that a calculator has no way to hold.

Do the tools work on mobile?

Yes. The calculators work well on a phone. The paste-based tools (reconciler, cohort builder, P&L bridge) are far easier on a desktop, since you are usually copying out of a spreadsheet anyway.
