About

A commons of professional calculators: 145 today across engineering, finance, statistics, and everyday decisions, growing weekly. Every one is a spreadsheet model computed live, with methodology and references on the page, so the number comes from verified logic rather than hand-written code or an AI's arithmetic. AI agents call the same calculators over MCP. Open beta; spreadsheet downloads and community contributions open when we leave beta. Free, ad-free, no account.

A source that found nothing is a measurement. A source that has not run is a gap. Neither means the launch lacks the thing.
