Description
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.

Could you build this?
Partial The directory website and spreadsheet calculation UI are straightforward, but authoring and validating hundreds of complex, citeable engineering and scientific models requires deep domain expertise.
What it would actually take: A real version requires a web frontend (e.g., Next.js) paired with an embedded spreadsheet calculation engine like HyperFormula or WebAssembly Excel models. The hard part is the domain modeling: authoring, verifying, and referencing dozens of intricate chemical engineering, stoichiometric combustion, and emissions equations. This requires multidisciplinary engineering and scientific domain specialists rather than purely software engineers.
