Structured calculation packs
Projects contain ordered trees of calculation sheets. Headings, notes, images and calculations follow a consistent layout that is ready for review and PDF output.
Built for engineering working
Less wrestling with the sheet. More thinking about the calculation.
AI Calc Sheet combines controlled document structure, a unit-aware calculation engine and an assistant whose proposed changes stay under the engineer's control.
Engineering units built in
Work naturally with units such as bar, MPa, ksi, millimetres and degrees. The server checks dimensional compatibility before accepting a result.
Variables flow through the tree
Define project-wide design conditions once. Child calculations can use them, see where they came from and override them locally when the engineering requires it.
AI proposals, never silent edits
Ask in ordinary engineering language to build, improve, explain or review a sheet. Inspect the proposed rows, assumptions, warnings and affected child sheets before applying anything.
Traceable check-ins
Keep an autosaved working draft, then create immutable named check-ins with a reason. Restore an earlier version as a new draft without rewriting the evidence.
Reusable team knowledge
Copy sheets safely between authorised projects or publish an immutable calculation template for everyone in your organisation to reuse.
Designed around judgement
The calculation remains the source of truth.
AI can accelerate the working, but the engineer reviews the assumptions, validates the method and decides whether a proposal belongs in the sheet.
