ChatGPT doesn't know what a takeoff scope is.
Ours do. Every agent is purpose-built for home builders — trained on your data, integrated with your workflow.
Join Beta — FreeHeadless access for AI agents
Headless means a connected AI agent can read and update Cornerstone records through MCP or the REST API without clicking through the website. You still have the full Cornerstone interface to inspect the work and take the next step.
Use the built-in Model Context Protocol server with ready-to-paste configurations for Claude Desktop, Cursor, and Windsurf.
Connect custom agents and automation tools using authenticated API calls. Tool schemas are available in Anthropic, OpenAI function-calling, and OpenAPI 3.1 formats.
Send Cornerstone events to your configured automation. Webhooks notify your workflow; the connected agent uses permitted API actions to do the work. External services require their own setup.
External-agent access is included with Pro+ and Enterprise. Connect your own tool with an authorized key; available actions depend on its permissions.
Your AI Construction Agent
Natural language commands to search, create, and manage your entire operation. Parts, vendors, homes, budgets — just type what you need.
AI Floor Plan Reader
Upload a PDF floor plan. Get 134+ scopes populated in under 60 seconds. No manual data entry, no missed line items.
Your AI Interior Designer
Name a home and a look. StyleSmith AI™ composes the complete design-selection set for that house — flooring, tile, cabinets, counters, plumbing, lighting, hardware — from your own catalog at your own retail pricing, then writes it into the Design Center on command.
AI Real Estate Listing Writer
Claude Sonnet writes professional MLS descriptions from your live home data. Room dimensions, upgrades, community details, lot size — all pulled automatically. One click to PDF.
Instant Answers, Zero Wait Time
Every feature, workflow, and permission documented and trained on Cornerstone PM™. Answers buyer and team questions 24/7 so you don't have to.
AI-Powered Vendor Bid Parser
Upload vendor bids in any format — Excel, PDFs, scanned documents, even photos of handwritten quotes. AI extracts every line item, fuzzy-matches your parts catalog and scopes, and imports as a Bid, Vendor Pricing, or Takeoff in one click. No more hours of manual data entry from vendor spreadsheets.
AI Vendor Presence Detection
The vendor rolls onto the jobsite. Your schedule already knows. Jobsite AI™ detects vendor arrivals from any camera, doorbell, gate, GPS, or check-in app — and auto-flips the matching scheduled task to In Progress. No phone calls. No manual check-ins. Camera-agnostic, sensor-agnostic.
No other construction platform gives builders natural language access to their own data. Ask anything. Get answers. Take action. All without leaving a chat window.
Every plan includes AI Support Agent. AI MLS Listing Generator on Builder+. Foreman AI + Blueprint AI on Pro. Bid Import AI + full API automation on Pro+.
