For engineering teams and solo engineersWhere engineering calculations become the report.
CalcAuthor is the cloud app that brings live, unit-aware calculations and professional report writing together in one place — write your engineering work once, and export a polished, submission-ready PDF.
One document, not two.
Every engineer knows the routine: run your calculations in one tool, write the report in another, then spend hours copying numbers back and forth, reformatting tables, and making sure the two stay in sync. One late change to a variable means updating it everywhere by hand.
One document. Always in sync.
CalcAuthor eliminates the split. Your calculations and your report live in the same document, from the first line to the final PDF. Change a variable, and everything that depends on it — text, tables, results — updates instantly. Write your report the way you already write a Word document, with real engineering math built directly into it.
What Sets CalcAuthor Apart
Traditional calculation software was built for one person, one file, one desktop. CalcAuthor was built for the way engineering teams actually work today.
Everything in One Place
Stop stitching together a calculation tool, a document editor, a file-sharing system, and a review process. CalcAuthor is the only platform that combines live engineering calculations, professional document authoring, and team collaboration in a single browser tab — no exporting to Word, no pasting screenshots of equations, no separate version-control workaround.
Documents That Update Themselves
Table of contents, list of figures, list of tables, list of references, and numbered citations all renumber automatically as you edit — add a section above your appendix and every cross-reference in the document catches up instantly. Nothing to manually renumber, nothing to forget before you send a calc package out the door.
Built-In Engineering Judgment
Conditional pass/fail formatting lets a calculation visibly flag its own result — green for pass, red for fail, styled and labeled the way your review process expects — directly inline with the math that produced it. Reviewers see the verdict at a glance instead of hunting through a spreadsheet for the check.
Real Team Collaboration, Not Just File Sharing
Role-based access (Admin, Manager, Individual), sub-teams, shared visibility controls, and a document-locking system that prevents two people from silently overwriting each other's work — all built in from day one. This isn't a shared drive with math bolted on; it's a platform designed around how engineering teams actually review and hand off work to each other.
Runs Anywhere, Nothing to Install
No license dongle, no per-machine activation, no "which version does the client have." CalcAuthor runs in any modern browser, on any operating system — open the same document from your office desktop or a job-site laptop and pick up exactly where you left off.
Deliverable-Ready Documents
Cover pages, headers and footers with your logo, document number, revision, and date, automatic page numbering, and clean print/PDF output — a CalcAuthor document isn't a worksheet you export and reformat, it's the deliverable itself.
A closer look at the document.
A real document, not a text box bolted onto a calculator.
Cover pages, running headers and footers, heading styles, captioned images, and tables — laid out the way a submission-ready engineering report is supposed to look.

Every list builds itself.
Add a heading, caption a figure, or title a table, and it's already accounted for — the Table of Contents, List of Figures, and List of Tables stay correct with the right page numbers, with no manual upkeep.
Beyond arithmetic.
Plot a function, take a derivative or integral, or solve a matrix — right inside the same calculation block, with units checked the whole way through.

Built for teams, not just individuals.
Organize your firm with Admin, Manager, and Individual roles, share documents across the team, and let document locking make sure two people are never editing the same calculation at once.
From formula to final report.
Three steps, one continuous document — no exporting, no copy-pasting, no separate tools.
Write
Start typing your report like a normal document — headings, paragraphs, tables, and images, styled with cover pages and headers/footers the way your firm already works.
Calculate
Drop in a calculation block anywhere. Type your formula, define your variables and units, and watch the result update live as you work — go beyond arithmetic with plots, derivatives, integrals, and matrices.
Export
When you're done, export to a submission-ready PDF with one click. Table of Contents, List of Figures, List of Tables, and References all generate automatically — what you see on screen is exactly what prints.
