BuilderTrend features · Contractor Foreman price · AI neither of them has
The AI that catches the $10,000 mistake before it's built.
Every company on the job works in one shared source of truth. When the electrician moves an outlet, the cabinet shop finds out before they cut — not on install day.
Owners and subs are free forever. No credit card to start.
The electrician hits blocking
He moves the outlet six inches and types one line into his daily log: “moved the outlet over 6" to clear a stud.”
Cohabuild reads it
The AI knows the cabinet shop's accepted scope references that exact outlet. It flags the conflict, names the shop, cites the log line, and recommends the call.
The GC makes one phone call
The cabinets haven't been cut yet. One revised drawing instead of a $10,000 remake and three lost weeks. That's the product.
Two ways in — both free to start
I own the property
See progress, photos, and budget in plain English. Approve decisions from your phone. Ask the AI what "rough-in" means at 11 PM. Free — not a trial, free.
Start free →I build for a living
Run your whole job — owner, subs, drawings, decisions — in one place, with an AI foreman reading everything for cross-trade conflicts. First project free, end-to-end.
Run your first project free →One source of truth
Drawings with revision history, scope packages, a decision log, and daily logs — shared by the GC, the owner, and every sub. No more "check the text thread."
AI reads everything
Every decision, drawing revision, and field note is screened against what every other trade committed to. Conflicts become flags: who's affected, what changed, what to do.
Humans decide
The AI never acts on its own. It cites its sources, states its confidence, and puts the call in the GC's queue. You can even ask a stronger model for a second opinion.

Priced for the crews the big tools ignore
Owners free. Subs free. General contractors pay one flat $99/month for up to 10 active projects — unlimited teammates, no per-seat math, first project free. The incumbents charge 3–10× that and still don't read your drawings.
Founding pilot program
We're onboarding a small group of GCs and owner-builders personally. Run your next project on Cohabuild free, tell us what's broken, and shape the product.
