Engineering documents
with embedded computation.

Write your report. Embed live calculations. Everything updates together.
No more screenshotting from Mathcad, Excel, and Bluebeam into Word.

Change an input. Everything recalculates. Your document stays formatted.

Web-based — Works on Mac, Windows, and any browser. No installation needed.

The engineering documentation problem

Sound familiar?

You write calculations in Mathcad.

Tables in Excel. Markups in Bluebeam. Reports in Word.

You screenshot everything into Word.

One by one. Dozens of images. Carefully aligned.

An input changes.

Now you redo it all. Re-run Mathcad. Re-export Excel. Re-screenshot. Re-paste. Hope you didn't miss any.

There has to be a better way.

One document. Everything live.

AltoDocs is a computational document editor — your report is the calculation. Embed live math, spreadsheets, drawings, and structural analysis directly in your document. No screenshots. No copy-paste. No separate files.

Embedded computation

Calculations live inside your document, not in a separate app

Auto-updating

Change one input — everything recalculates and reformats

Single source of truth

Your report, your calcs, your drawings — one file, always in sync

What you get with AltoDocs

Six powerful tools. One document. No screenshots.

MathCanvas

Live calculations with unit-aware formulas — embedded in your document.

Replaces: Mathcad

AltoSheets

Excel-compatible spreadsheets embedded directly. Multiple views, always in sync.

Replaces: Excel screenshots

AltoMarkups

Annotate drawings with dimensions, callouts, and measurements — at the correct scale.

Replaces: Bluebeam screenshots

AltoBeam & AltoFrame

Built-in structural analysis for beams and 2D frames. Results auto-update.

Replaces: Separate structural software

AltoCAD

2D CAD drawings inside your document. Draw, annotate, and dimension — without leaving your report.

Replaces: AutoCAD / separate DWG files

Python

Full Python in your browser. NumPy, SciPy, pandas, Matplotlib — no installation.

Replaces: External Python setup

Why not just use Mathcad?

Mathcad is math-first. AltoDocs is documentation-first with embedded computation. Your report is the calculation — not a separate file you screenshot into Word.

Mathcad + Word

AltoDocs

Approach

Math-first, separate from report

Documentation-first, embedded computation

Report workflow

Screenshot into Word

Calculations live in the document

When inputs change

Re-screenshot everything

Everything auto-updates

Spreadsheets

Separate Excel files

Embedded, always in sync

Drawing markups

Separate Bluebeam files

Annotate directly in document

2D CAD drawings

Separate AutoCAD / DWG files
