At Mastt, we’re building the world’s first Agentic AI for construction project teams
Used by project leaders building the future around the globe
Agent by Mastt runs on the same frontier models as Claude, ChatGPT and others. The difference is everything around it — purpose-built for construction, wired into your live project data, company knowledge, documents and email, with governed writes and outputs you can trust.
Keep it — it's a great general assistant. Mastt Agent is the difference between “an AI that writes well” and “an AI that already knows this project's RFI log, your operating procedures, and last month's board report — and can prove where every number came from.” Your subscription buys intelligence; Mastt Agent adds domain fit, live context, evidence, and governance on top of it.
You can — for one project, maintained by one person, current as of the last upload. Now multiply that by every project in your portfolio, keep the registers live as they change, apply org-level permissions, add an audit trail of what the AI wrote, and make every output traceable to a source page. That's not a Project setting — that's a product. Mastt Agent is that product, already built.
They could start. But the build isn't the API call — it's the registers data model, document indexing and page-level citation, deterministic calculation, permissioning, audit log, versioning, templated outputs, the email agent, and the domain skills for construction project delivery. That's a multi-year product roadmap, followed by permanent maintenance, with your IT team accountable when it breaks mid-dispute. Mastt Agent gives you all of it on day one, so your engineers can stay on your own roadmap.
We give you access to the same frontier models as Claude, ChatGPT and other providers — deliberately, so you always get the best intelligence available as models improve, without being locked to one vendor. The product is everything the models can't do alone: the workspace, registers, documents, company knowledge, evidence chain, governance, and email agent sitting on top of them.
Your data stays inside your governed Mastt workspace, with org- and project-level access control and a full audit log of every AI-driven change — not scattered across personal chat histories outside your project's system of record.
Yes — variation totals, EOT day counts, and payment cert reconciliations are computed deterministically against your live registers, with the working shown. Nothing is estimated or rounded in the model's head.
Every Mastt Agent artefact carries source references back to the exact meeting, register entry, or document page behind each line — so a progress report, EOT claim, or payment cert can be evidenced months later in a dispute, an audit, or a client challenge.
