Build |
The only construction platform with three built-in AI agents.
Foreman AI executes actions from plain English. Blueprint AI reads floor plans and generates material takeoffs in seconds. The FAQ Chatbot knows every feature. All three agents are wired directly to your data — no setup, no consultants.
The full platform, in 60 seconds.
From sales pipeline to homeowner portal — watch how Cornerstone runs your entire operation.
Beta is limited to 100 builders. No credit card required.
Built for how builders
actually work.
Real screens from a real product. No mockup smoke and mirrors — this is exactly what you get on day one. Dark mode included. (You're welcome, night owl builders.)
Track every deal from first contact to closed sale.
Kanban-style pipeline with color-coded stages. See your full book of business at a glance - Sales, Permitting, Design, and Construction columns show exactly where every home stands.
Four AI agents.
Zero other platforms have one.
ChatGPT doesn't know what a takeoff scope is. Ours do — and they're wired directly to your data. No integrations, no setup, no consultants.
Foreman AI
Your AI Construction Agent
47 purpose-built construction skills. Not a generic chatbot — Foreman reads AND writes your data. Parts, vendors, homes, MLS listings, exports, design center, and more.
Blueprint AI
AI Floor Plan Reader
Upload a floor plan PDF. Blueprint AI extracts every room, fixture, and material scope in under 60 seconds. One click imports 134+ scopes into your budget.
MLS Listing Agent
AI Real Estate Listing Writer
Claude Sonnet writes professional MLS descriptions from your live home data — room dimensions, upgrades, community info, lot size. One click to a print-ready PDF.
FAQ Chatbot
Always-On Help Desk
ChatGPT chatbot on every page. Knows every feature, workflow, and permission. Built-in documentation that actually talks back.
Buildertrend has forms. CoConstruct has buttons. Cornerstone has agents.
No other construction platform gives builders natural language access to their own data. This isn't a chatbot bolted on — these are purpose-built agents that understand construction workflows, supplier catalogs, and production builder operations.
