Calculeaf

Calculeaf is a web-based engineering calculation worksheet designed for technical professionals who need to perform unit-aware calculations, document formulas, and create plots within a single, shareable document. The platform is intended for use cases such as structural checks, mechanical calculations, unit conversions, and design notes, providing an environment where equations and explanatory text are integrated on the same page for clarity and traceability.

The tool supports arithmetic and conversions across SI, USCS, and CGS unit systems, allowing users to evaluate formulas with full unit awareness and perform derived unit calculations. Worksheets can include a mix of math regions, narrative text, plots, images, headers, and are printable for documentation purposes. Calculeaf enables users to save their work, create reusable templates and snippets, and share copies of calculation sheets. It offers a variety of engineering functions, including constants, statistical operations, matrices, vectors, comparisons, and iterative calculations. Users can add line, area, and scatter plots directly alongside the equations that generate them, enhancing the interpretability of results.

A notable feature is AI-assisted authoring, which allows drafting calculations from a prompt and running worksheet overviews to check the logical flow of a sheet. xmcd) files, converting their regions, formulas, and units into editable worksheets within the platform. This makes it a viable alternative for engineers accustomed to Mathcad, especially for everyday calculation sheets that require := definitions, unit-aware evaluation, and printable output.

Calculeaf is accessed entirely through the browser, requiring no installation. It is free to use and does not require sign-up to try. The platform is positioned as a next-generation calculation sheet, distinct from traditional spreadsheets, and is tailored for engineers seeking readable, organized, and technically robust calculation documentation.
