Build what you committed to.
Alex is an AI assistant for building contractors. It reads your drawings, programme and bill of quantities, answers your site team on WhatsApp, and flags the moment the job drifts from what was agreed.
Built for site managers, project managers and QSs, and the directors who answer for every job.

(01) How it works
Load the job. Ask from site. Hold the line.
Load the job
Add the drawings, the programme, the bill of quantities and the contract to a project. Alex reads every page and builds a model you can play the programme across.
See the modelAsk from site
Your team asks on WhatsApp or by phone from site, and in chat or by email from the office, and gets answers from the project's own files.
See it on siteHold the line
Decide inside Alex. The decision, its owner and its reasoning go on the record, and Alex checks the job against it every night until handover.

From the drawings to handover, week by week
Alex turns your drawings into a 3D model and lays the programme and the bill of quantities across it. Scrub to any week to see what should be standing and what should have been spent.

Alex · on programme
The programme as planned, with the bill of quantities spent along it.
An illustrative job, not a customer's. On yours the drawings, the programme and the bill are your own, and the model is for looking at and talking through, not for measuring.
(03) On site
Ask from the deck, not the site office
Your site team already knows how to send a voice note. Now the answer comes back from the project's own files, before the truck leaves the yard.
AlexAlex's own numberToday
Alex has its own number
Your team messages or rings Alex's WhatsApp number, and it answers only the numbers you have listed. It never reads anyone's own WhatsApp, never starts a chat, and what you send it stays yours.
Voice notes, answered
Talk it through instead of typing. Alex transcribes the note and answers from the project's drawings, programme and bill.
Alex answers the person who messaged it, and never sends a message in your name.
“Icarus”, Empire State Building, 1930. Lewis W. Hine.
(04) Decisions and drift
Jobs are rarely lost to one bad call. They are lost to the calls nobody wrote down.
The instruction given on site, the variation agreed on the phone, the date moved in a meeting: Alex keeps each one with its owner, its date and its reasoning. Every night it checks the job against them and flags what has slipped, and who owns it, so at the final account nobody is arguing from memory.
Big calls, argued from six sides
Before you decide, Alex weighs the call from every side of the job, from the margin and the programme to the contract and the crews, and brings it to one recommendation.
Steel is up 11%. Absorb it, or re-tender the frame?
Weighs the margin.
Weighs the programme.
Weighs the supply.
Weighs the contract.
Weighs the crews.
and they reconcile
One call, with the reasoning on the record.

(06) Sign-in and your data
Your company's data stays its own
Sign in with your work email and a password or one-time code, or with Google or Microsoft. Alex asks Google and Microsoft only for your name, email address, and profile picture, and uses them solely to create your account, sign you in, and show colleagues who recorded a decision. Nothing else is requested. Your company owns everything it records in Alex, and we never sell it. Read our Privacy Policy and Terms of Service.
Answers from models that keep nothing
The models that write Alex's answers run with zero data retention and data collection switched off. Calls, voice notes and document reading go through the processors the Privacy Policy names.
Personal stays personal
A connected mailbox, a WhatsApp chat or a private note is its owner's alone, never shown to a colleague or an admin.
The next job you win. Run it inside Alex.
Every drawing, date and rand on the job in one place, answers for your site team, and the reasoning behind each call still there at the final account.
