Docs.
Engineering, explained.
Write your document. Add calculations, spreadsheets, drawings and analysis inside it.
A report in the AltoDocs editor, which is laid out like Word: a ribbon with Home and Insert tabs, a navigation panel with the headings, and the page. Under the headings sit a spreadsheet with the loads, a MathCanvas calculation that reads the spreadsheet, a sentence that quotes the calculated moment, a beam with its moment diagram and a roof plan with a dimension and a markup. They are live blocks added from the Insert tab, not pictures pasted from other programs: when a load changes in the spreadsheet, the calculation and the sentence follow.
Apps inside your document.
Add one where you are writing.
MathCanvas
Equations with units, written like on paper. Change an input and every result follows.
Also a standalone appSheets
A full spreadsheet inside the report. Show only the cells you choose.
Python
Notebooks that read the values in your report. Plots and results stay beside the code.
MarkupCanvas
Turn a screenshot or sketch into a figure: calibrate, dimension and annotate.
Beam analysis
Spans, supports and loads in. Shear, moment and deflection diagrams out.
Frame analysis
Portal and gable frames with reactions and member forces.
Loads
Wind and snow to the Eurocodes. Made for Denmark, with the Danish National Annex.
Cross-references
Quote a result in a sentence. The number updates with the calculation.
Best Practice blocks
Save a section once. Insert it in the next report and keep editing it.
Collaboration
Send a colleague a link and work in the document together.
PDF and Word
Send the finished report as a PDF or a Word file.
Try Docs
A real report, open for editing. No sign-up, and nothing you change is saved.
Loading the report…
One report, the whole team.
Sharing is a link. Send it to a colleague and hop into the document together.

A few things to know
Is Docs free?+
Yes. Writing, calculating and sharing reports is free, and so are MathCanvas and AltoCad. Only AI access is paid: see pricing.
Do I have to use every app?+
No. A report can be plain text with one calculation. Add a spreadsheet, a drawing or an analysis when the work needs it.
How is this different from MathCanvas?+
MathCanvas is the calculation app on its own. Docs is the report around it: the same calculations, with text, drawings and analysis on the same page.
Which design codes do the loads follow?+
Wind and snow follow the Eurocodes with the Danish National Annex. They are made for projects in Denmark, and we are still refining them. The other apps are not tied to a country.
Can my team work in the same report?+
Yes. Send a colleague a link and you edit the document together. There are no copies to merge.
Can I get my report out?+
Yes. Export it as a PDF or a Word file whenever you need to send it.
