Hand off the counting, not the judgment.

Let MillOS do the counting. You keep the final say on every line. See how a whole bid comes together in under four minutes.

Read the transcript

The problem0:00

Every building starts as a set of drawings. Someone has to read every line, and turn it into a price.

Every project starts with a number. Before a single cabinet gets built, somebody has to estimate it. And that somebody... is you.

Estimator: Okay. Base cabinets, uppers, countertops... let's start counting.

The set lands. Hundreds of sheets. So you hop sheet to sheet. Scale it. Count it. Measure it. Check the spec. Type it in. It takes days. And every scope gap is on you.

Seven in ten building contractors say estimating jobs are hard to fill. So good shops pass on good work.

Maybe you've tried an AI chat. It hands you a spreadsheet. But where did this number come from? You'd check every line by hand. And you'd still switch between six tools.

Meet MillOS1:03

That's why we built MillOS. The AI-native workspace for architectural estimation. Built by industry experts and AI engineers. Think Claude Code... but for estimators.

Then we gave it the tools of the trade. A Takeoff Studio where you mark and measure yourself. A file cloud, like your own drive. A workbook with the spreadsheet tools you use. Your product library. And a team of Experts that does the work.

Set up and send the bid1:35

Getting set up is easy. Do it once. Your product library, your pricing rules, your shop's instructions. Invite your team, and you're ready.

Create a project, upload the bid, and ask. First, it asks a few quick questions. Then a team of Experts goes to work, area by area. Watch the marks appear as it measures. If something doesn't add up, it raises an RFI, and keeps going.

Want a second set of eyes? An independent Expert can check the priced estimate. So close the laptop. It keeps working.

Review with receipts2:14

When you're back, the estimate review is waiting. Click any line, and see exactly what was measured, on which sheet, and why.

Estimator: Huh. It actually shows its receipts.

Ask it anything, like a colleague. Approve, or ask for a change, and send it back. Fix a mark yourself, or edit the workbook, and the numbers follow. And nothing goes out until you approve it.

Bid week2:46

Now picture bid week. Three sets running at once, while you walk a job site. A question pops up on your phone, and you answer it between meetings.

By bid day, the numbers are in... and you still made it home for dinner. Your drawings and prices stay private to your shop. And it gets better with every bid. Hand off the counting, not the judgment.

Or keep counting by hand. The shops that bid more, win more.

We're opening our pilot to a small group of millwork shops. Tell us why it should be you. Apply for early access.

Everything an estimate needs, in one place.

Five parts, built together, so the AI and your team work in the same place.

The estimator

Our own AI system, built for architectural estimation.

Think Claude Code or Codex, made for estimators, on the latest frontier models. It reads the set, measures, prices and asks when drawings disagree.
