AI Estimating Software for Home Builders

What is Assembli?

Assembli is AI-powered construction estimating software built for residential home builders. You upload your architectural plans, and our AI extracts key metrics, applies residential estimating logic, and generates a preliminary cost estimate in minutes — not hours. It's designed for builders doing 1 to 25+ homes per year who want faster, more accurate estimates without the spreadsheet headaches.

How does Assembli's AI estimating work?

Assembli uses a four-step process. First, you upload your architectural plans digitally. Then our AI automatically extracts key measurements and metrics from the drawings. Next, residential estimating logic is applied to that data. Finally, you get a preliminary estimate broken down by category — foundation, superstructure, exterior enclosures, and more — along with an AI Agent that answers questions and flags potential risks.

How much does Assembli cost?

Assembli offers two simple annual plans. The Starter plan is $2,500 per year and includes up to 3 users, unlimited jobs and estimates, customizable cost templates, and export to Excel, CSV, and PDF. The Growth plan is $4,500 per year and adds unlimited user seats, custom cost templates built by our team using your actual trade data, dedicated onboarding, priority support, and faster AI processing. Both plans are billed annually with no per-project fees.

How accurate are Assembli's estimates?

Assembli generates preliminary estimates using AI-driven analysis of your architectural plans combined with residential estimating logic. The platform is designed to give you a reliable rough estimate early in the process so you can confidently answer the question 'What will this house cost to build?' before investing hours in a detailed manual takeoff.

Does Assembli work for commercial construction?

Assembli is specifically designed for residential construction. Our AI models and estimating logic are trained on residential building data, which means they deliver the best results for home builders. If you build residential homes — whether custom, production, or spec — Assembli is built for you.

Do I need AI experience to use Assembli?

No. Assembli is designed to be intuitive for builders, not tech experts. You simply upload your plans and the AI does the heavy lifting. Our built-in AI Agent also guides you through the process, answers your questions, and helps identify potential risks in your project. If you can upload a file, you can use Assembli.

Can I see Assembli before I pay?

Yes. We offer a live demo where we run your actual plans through the system so you can see exactly what you're getting before committing. Book a 30-minute demo and our team will walk you through a real estimate using your project files.

What risks does Assembli help identify?

Beyond cost estimates, Assembli's AI flags four types of risk early in the planning phase: schedule risk, cost risk, site risk, and compliance risk. This helps you make smarter decisions before construction starts, reducing surprises and protecting your margins.
