A new way to build engineering calculations

From first calculation to final report. One document.

We’re building a modern calculation workspace for engineers to create, document, and turn calculations into report-ready documents without wrestling with spreadsheets.

Engineering calculations that show their work. Not spreadsheets. Not code. A new kind of calculation document built for engineers.

Real notation

Type it like you'd write it.

Enter equations the way they appear in textbooks. No cell references, no hidden macros — your formula renders instantly into publication-quality math.

Diameterd=10mm
Thread pitchp=1.5mm
As=π4(d0.9382p)2A_s = \frac{\pi}{4} \left( d - 0.9382 \cdot p \right)^2

Unit safety

Every unit, accounted for.

Define a value once and its units follow through every step. Catch mismatches before they reach the field — not after.

Full traceability

Nothing hidden, nothing assumed.

Toggle open any result to see the substitution, the arithmetic, and the source formula. Reviewers check the math in minutes, not hours.

σ=FA\sigma = \frac{F}{A}
Substituteσ=12,000 N57.99 mm2\sigma = \frac{12{,}000 \text{ N}}{57.99 \text{ mm}^2}
Calculateσ=206.9 MPa\sigma = 206.9 \text{ MPa}
206.9 MPa — Within allowable

Report-ready

The calc is the deliverable.

Stop copying results into Word. Your calculation is already formatted, signed, and ready to submit — print it, share it, archive it.
