CalcAuthor is engineering calculation software for engineers who need to produce submission-ready calculation reports, not just get a number. You write the calculation. CalcAuthor keeps everything around it correct as you edit: Unit-aware math — mixed units (kN/m, GPa, mm⁴) convert automatically,...

As answered by people managing Wolfram Mathematica and CalcAuthor.
CalcAuthor's answer:
Most tools either calculate or document — not both. CalcAuthor treats the calculation and the report as one connected object: units convert automatically within a formula, and the parts of an engineering report that normally require manual upkeep — table of contents, citations, cross-references, figure numbering, running headers — update themselves as the document changes. The output is a submission-ready PDF, not a raw result that still needs formatting.
CalcAuthor's answer:
Spreadsheets don't understand units and produce no document structure. Legacy calculation tools like Mathcad require a desktop install and still leave document-level upkeep (TOC, citations, figure numbering) to the user. CalcAuthor runs in the browser, is built for teams (shared style presets, safe concurrent-editing via document locking), and turns a calculation directly into a submission-ready report without a separate formatting pass.
CalcAuthor's answer:
Structural, civil, and mechanical engineers — and the firms they work for — who need to produce calculation packages for permit submissions, peer review, or client deliverables. Both individual engineers and engineering teams.
CalcAuthor's answer:
Built on .NET 8 (C#) for the API and Blazor WebAssembly for the client, with PostgreSQL via Entity Framework Core for data. Stripe handles billing, Resend handles transactional email, and Cloudflare Turnstile protects signup from automated abuse. Hosted on Render.
CalcAuthor's answer:
CalcAuthor is used by individual structural, civil, and mechanical engineers producing calculation packages for permit submissions and client deliverables, as well as engineering teams and firms that need consistent report formatting and unit-aware calculations across multiple engineers working on the same projects.
CalcAuthor's answer:
CalcAuthor started from the day-to-day frustration of writing an engineering calculation report: switching between a calculation tool, a word processor, and a spreadsheet just to produce one document. Every edit meant redoing work by hand elsewhere — adding a section meant renumbering the Table of Contents, List of Figures, and List of Tables manually; mixing unit systems meant tracking conversions yourself with no safety net; and keeping formatting consistent across a long report meant constant re-checking instead of writing. CalcAuthor was built to collapse that into one tool, where the calculation, the units, and the document structure all stay correct automatically as the report is written.
