Features
📐 Unit-aware Math
Calculeaf's core engine supports full arithmetic, conversion, and evaluation using SI, USCS, and CGS unit systems. It handles derived units and ensures dimensional consistency throughout calculations, eliminating manual
📄 Document-style Worksheets
The platform provides a flexible page where math regions, explanatory text headers, images, and various plots (line, area, scatter) can be combined into a single, printable calculation sheet. This mimics traditional engi
🤖 AI-assisted Authoring
This feature helps users draft initial calculations from descriptive prompts and run worksheet overviews to check the logical flow and completeness of a sheet. For instance, an engineer could prompt "calculate bolt stiff
Use cases
Perform structural load and deflection checks.
Document mechanical design calculations with units.
Create reusable templates for standard engineering analyses.
Share calculation methodology with team members.
Convert between SI and USCS units within formulas.
FAQ
Calculeaf is a web-based engineering calculation worksheet for creating unit-aware formulas, notes, plots, and reusable technical documents directly in your browser.
Yes. It fully supports unit-aware arithmetic and conversions across SI, USCS, and CGS unit systems, including derived units.
No. It is designed as a calculation sheet or worksheet, where equations and explanations coexist on a page in a document style, not a cell-based grid.
Yes. On the sheet body, math and dropdown regions evaluate sequentially from top to bottom, then left to right on the same row.
Define a variable name using the ':=' operator on a line above any line that intends to use that variable.
You can add line plots, area plots, and scatter plots directly alongside the equations that generate the data.
Yes. Worksheets can be saved, used as templates, snippets can be created, and copies can be shared with others.
The tool includes constants, statistical functions, matrix and vector operations, comparison operators, and supports iterative calculations.
Yes. AI-assisted authoring can draft calculations from a text prompt and provide overviews to check a sheet's flow.
Yes. The platform is currently free to use with no install, accessible directly via the web app.
