Live maths
Define variables with :=, reuse them anywhere on the sheet, and see
results rendered inline as you type.
Maths Explore
A calculation pad for engineers. Real maths on paper-like sheets; every expression evaluates live, units checked as you type.
What is Maths Explore?
Section titled “What is Maths Explore?”Maths Explore is a webapp for engineering calculations. You place blocks of maths, text and diagrams anywhere on paginated sheets (A4 or US Letter). Everything evaluates in reading order against one shared scope, so results update the moment you change an input. Think spreadsheet, except the maths reads like maths.
Units built in
Attach units like 2.mm or N.m to any value. Results carry their
units, and you can convert them per block.
Mathew, the AI nerd
Describe a calculation in plain language and Mathew writes the blocks for you, straight onto your sheet. One-click undo, in case you disagree.
Your files, your machine
Calcsheets autosave to your browser and save to portable .mez files
on disk; print or export to PDF when you’re done. No cloud, no lock-in.
First steps
Section titled “First steps”You don’t need an account to start. The sample calcsheets open straight in the workspace, so you can change an input and watch every result follow. Each one opens read-only; press Unlock to edit when you want to experiment. Free on every plan, trial or no trial.
When you’re ready for your own work, every new account starts with a 14-day free trial of the Professional plan (no card required). Head to Getting started to create an account and build your first calcsheet, then work through the guides in the sidebar for blocks, syntax, units, templates and the rest.
