At 91±¬ÁÏ, 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 91±¬ÁÏ 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.
Yes. 91±¬ÁÏ Agent connects to the systems your projects already run on, including Outlook and Microsoft Teams, SharePoint, Slack, Xero and Procore, so it works from your live project data instead of copies pasted into a chat window. Those connections are governed and permissioned, and every action the Agent takes is logged, which a personal Claude or ChatGPT account cannot give you.
Keep your subscription, they are great general assistants. 91±¬ÁÏ Agent is the difference between an AI that writes well and an AI that already knows this project's RFI log, cost report, operating procedures and last month's board report, and can prove where every number came from. Your subscription buys intelligence. 91±¬ÁÏ Agent adds construction domain fit, live project 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 across every project in your portfolio, keep the cost and risk registers live as they change, apply workspace and project permissions, add an audit trail of what the AI wrote, and make every output traceable to a source page. That is not a Project setting, it is a product, and 91±¬ÁÏ Agent is that product, already built.
They could start, but the build is not the API call. It is the registers data model, document indexing with page-level citations, deterministic calculations, permissions, audit logs, versioning, templated outputs, the email agent and the construction delivery skills. That is a multi-year roadmap plus permanent maintenance, with your team accountable when it breaks mid-dispute. 91±¬ÁÏ Agent gives you all of it on day one, so your engineers stay on your own roadmap.
No. 91±¬ÁÏ Agent runs on the same frontier models as Claude and ChatGPT, and it stays multi-model on purpose, so you always get the best intelligence as models improve without being locked to one vendor. The product is everything the models cannot do alone. It is the workspace, registers, documents, company knowledge, evidence chain, governance and email agent that sit on top of them.
Your data stays inside your governed 91±¬ÁÏ workspace, encrypted in transit and at rest, with workspace and project permissions and a full audit log of every AI-driven change. Nothing you put in is used to train AI models, because the providers do not train on your inputs or outputs, unlike a personal Claude or ChatGPT account where your chats may be. Your project data is not scattered across personal chat histories outside your system of record. For the detail, read our data privacy and cyber security pages.
Yes. Variation totals (change orders), extension of time day counts, cost report forecasts and payment certificate reconciliations are computed deterministically against your live registers, with the working shown. Nothing is estimated or rounded in the model's head, so the figures match your source data.
Every 91±¬ÁÏ Agent output carries source references back to the exact meeting, register entry or document page behind each line. So a progress report, extension of time claim or payment certificate can be evidenced months later in a dispute, an audit or a client challenge, right down to where each figure came from.
