Build |
The only construction platform with five built-in AI agents.
One AI. Every workflow.
Foreman AI™ is the brain behind Cornerstone — 396+ skills, 5 specialized agents, and a full REST API. Build your own phone agent, vendor SMS bot, or workflow automation on top of the same engine that runs your jobs.
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.)
Every home, every stage — one kanban board.
Drag-and-drop sales pipeline from contract to construction. See every home in Sales, Permitting, Design, and Construction at a glance — buyer assigned, current task, community, lot. Filter by community, home type, or status. The board sales managers live in.
Five 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.

Already running Claude, ChatGPT, n8n, Make, or Zapier? Use a voice provider like Twilio, Bland, or Retell to text and call subs? Point them at Cornerstone. Connect Claude Desktop, Cursor, or Windsurf to the built-in MCP server in ~30 seconds (the no-code on-ramp), or drive the full REST API for total control. Pro+ unlocks the same toolbox Foreman AI uses internally— every one of Foreman's 396+ skills is exposed as a REST endpoint, plus 37+ named webhook events. We built the API on top of Foreman: every time we ship a new skill, your BYOA agent gets it automatically. Read homes, schedule tasks, send bid requests, update POs, fire SMS to subs, notify homebuyers the moment a milestone hits.
