Your information is spread out.
Drawings sit in project folders, take-offs in another app and old costs in SharePoint. Your AI needs to know where to look.
The ContractorOS app
Give your AI your way of working.
ContractorOS connects the AI app you already use to construction workflows, your company’s information and your own templates. Ask for an estimate, a scope or an RFI the way you normally would, and your AI follows the workflow and hands you a draft in your format.

Why it helps
Your AI knows construction. It doesn’t know your company yet.
The work has a process.
An estimate needs quantities, rates, prelims and margin, with your team checking it along the way.
Nobody wants to learn 100 prompts.
Your team should be able to describe the job and get the right steps and template with it.
Every company does it differently.
Methods and templates change, and copies pasted into everyone’s chats go out of date.
How it works
Your AI does the work. ContractorOS brings your system.
It’s one connection to the methods, information and formats your company uses, and there’s nothing to install.
-
Ask for the work
Type it in Claude, ChatGPT, Gemini, Copilot or another AI app, the way you’d ask a PM.
-
Confirm the workflow
Your AI finds the matching workflow in ContractorOS and waits for your go-ahead.
-
It pulls what the job needs
The workflow’s steps, your company’s rules and your template.
-
Check the draft
It works through the steps in your chat and hands you a draft in your format.
Your files stay where they are.
Your AI opens them through its own Google Drive or SharePoint connection, with the access you approve.
Make it yours.
Start with the ContractorOS workflows and more than 120 templates, then add your own rules, rates and templates.
You stay in charge.
Your AI asks before it saves any change, and you still own and check every number.
Getting set up

Frequently asked questions
Who can use the ContractorOS app?
ContractorOS members. Sign in with the email you joined with. If it won’t let you in, email [email protected].
Which AI apps does it work with?
The app has step-by-step guides for Claude, ChatGPT, Gemini and Microsoft Copilot. Other AI apps that support custom connectors (MCP) use the same address. You need your own account, on a plan that allows custom connectors.
Is it another AI app?
No. ContractorOS holds the workflows, your company information and your templates. Your own AI app reads what each job needs and does the work.
Which workflows are in it?
Pre-construction and estimating, procurement, head contracts, subcontracts, project controls, cost and finance, documents and design, quality and handover, safety and environment, and business management. Each one is broken into the steps you’d follow on a job.
Can I change a workflow to suit my company?
Yes. Add your house rules, rates and notes, attach your own templates or change a workflow’s steps. Every change is saved as a version you can roll back.
Do I have to move my project files?
No. They stay in your own drive, and your AI opens them through its own Google Drive or SharePoint connector when a job needs them.
What happens if I leave ContractorOS?
Access follows your membership. When your membership ends, the app stops working in your AI.
