Modular MathDesk light workspace previewFaster calculation work, with the review trail intact
Modular MathDesk helps engineering, science, and math-focused teams move from blank page to checked calculation faster by making reusable math, team module collaboration with version history, and assistant review* part of the same workflow.
Primary workspace
Calculation documents that stay readable
Build engineering and scientific calculations in a rendered document that keeps equations, assumptions, units, diagrams, and explanatory text together. The workflow is designed for speed without losing the structure reviewers need later.
Dark mode calculation documentEquation solving
Solve from the math you already wrote
Define a relationship, enter known values with units, and ask MathDesk for the remaining variable. Calculations stay readable while the app handles the rearranging and unit-aware solving.
Natural equation solving^Equation solving currently supports one unknown at a time. Parallel equations and systems of equations are not yet supported, but are on the roadmap.
Math repository
Reviewed modules, ready when the project needs them
Keep proven equations and modules in shared repositories so technical teams can search, compare, insert, and reuse calculation logic without rebuilding it from scratch. Teams can flag issues, upvote useful work, fork improvements, and leave a clearer audit trail around the assumptions behind each calculation.

Verified methods inside live documents
Insert reusable modules directly into working calculations so tested methods and project-specific inputs live in the same document. This speeds up repeated work while helping reviewers focus on the assumptions and changes that matter.

A second pair of eyes, or hands.
Use handpicked AI models from Anthropic, OpenAI or Google or select your favourite from 100s of others via a BYO OpenRouter key. Lean on the assistant as a math partner for checking steps, inspecting assumptions, and catching document-quality issues.
Math assistant feature switcher*Cost, speed, and accuracy may vary based on the difficulty of the problem. AI can make mistakes; all outputs must be checked and verified by the user.
Repeatability and auditability
Reusable work compounds across a team
Shared repositories, versioned modules, review signals, and forkable calculation blocks help teams avoid paying the same checking cost on every project. When a method improves, the benefit can travel back through the repository instead of staying trapped in one file.
Repository detail and review controlsMultiple step-function improvements
A workflow that seems obvious once you try it. From the very beginning, calculations are legible, using tested methods. You find yourself no longer digging through old template files and folders looking for a correct method. The natural evolution of the humble calculation sheet on paper: Modular MathDesk is the modern take on readable handwritten calculation sheets, with team collaboration and improvement built-in, alongside cutting-edge AI models for drafts, and math collaboration.
Start in the desktop app on Windows or MacOS
Keep the working math readable from the very first draft in a fluid and fast interface.
Reuse calculation modules
Pull team-reviewed math from the repository instead of rebuilding every time.
Work together with the assistant
Use a BYO OpenRouter key to speed up input, formatting, and verification. Deeply integrated - no copy & paste from a second window.
Math-centric calculations that work the way you think
Not a spreadsheet. Not a word processor. A purpose-built tool for engineering, science, and mathematics work that needs accuracy, traceability, and speed.
Live Math Evaluation
Write expressions in natural math notation and see results instantly. Powered by a full symbolic math engine with dimensional analysis.
Unit-Aware Computation
Define calculations with physical units — mm, kN, MPa. The engine tracks units through every operation and catches dimensional errors.
Modular Documents
Create reusable calculation modules. Insert a reviewed method into any project and it inherits the document's variables automatically.
Change One, Update All
Modify an input value and every dependent result recalculates in real time. No more manually chasing formulas through a spreadsheet.
Professional Output
Export clean, formatted PDF reports with headings, formulas, results, and commentary. Ready for client delivery or peer review.
Custom Variables & Units
Define project-level variables, presets, and even custom unit systems. Tailor the environment to your technical workflow.
