CalcTree Overview

CalcTree is a cloud-based calculation management platform built for structural, geotechnical, and other engineering teams. It brings calculations, reusable templates, and reference documents together in one collaborative workspace, replacing scattered spreadsheets and desktop calculation files. Teams can build calculations, connect them to live data sources (Parameters), and collaborate on shared Projects in real time. CalcTree AI reviews new calculation work against design documents and relevant standards, aiming to speed up quality checks and catch errors before they reach a stamped deliverable. The platform integrates with Excel and Python, exposes a GraphQL API, and supports third-party plugins for teams that want to connect it to their existing toolchain. CalcTree offers a Free plan with limited pages, storage, and AI usage for individuals or small teams to trial the product; a Business plan priced per user per month with unlimited pages, workspaces, storage, and templates plus a hosted Python IDE; and a custom Enterprise plan billed as a flat annual fee with account-wide AI allowances, custom integrations, and optional SSO and private tenancy for larger organizations.
