Construction management software
From the estimate to the final invoice: drawings, tasks, timesheets, RAMS and job costs, on every phone and in the office.
On a typical £4M nine-house scheme, builders save around £112,000 using BuildersAI.
01
£80,000
less rework from out-of-date drawings on a £4M scheme
Drawings live in WhatsApp groups, email chains and folders that were never set up for a site. BuildersAI is designed for construction: drawings organised the way a site works, old revisions marked superseded, and markup on the drawing itself, so everyone finds the right one in seconds and nobody builds off an old one.
02
One record
of every day on site, shared by the whole team
Instructions given over the phone, in passing or in a group chat get missed or remembered differently. Everyone works from the same source of truth, with a clear record of what happened and what was said on site each day.
03
£32,200 a year
of time saved with seven people on site
No more paper trail. RAMS and inductions are signed in the app by the whole team. Timesheets work the way your team does, from QR code check-ins or entered by hand. Supplier invoices, change orders signed by your client and every payment are tracked against the job, so jobs get done quicker and cost less.
Independently backed & compliant
Built and run in the UK
Every plan includes all of these, as does the 14-day trial, and nothing is sold as an extra.

Comparing options? Our guides explain what site management software is, compare planning tools that work on site, project management software for UK builders and site management apps, and set out how to choose management software with a side-by-side comparison of UK construction software.
For too long, UK builders have made do with software designed in America and elsewhere, built around other countries' contracts, taxes and regulations rather than the way British sites actually work. BuildersAI is built and run in the UK, for UK builders. Our aim is to give UK construction tools as good as anyone's in the world, and to help British builders compete on the global stage.

Snagging, first fix, groundworks and trades, the words your site already uses.
The office runs the job in the web app on the left. The site works on the phone on the right.
Running the job
On site
Bournville Gardens demo project
Tasks, snags, inspections, RFIs and deliveries sit on one board. You can see what needs doing, who has it and what is holding it up.
Start your 14-day free trial and try BuildersAI out for yourself. Tell us what kind of sites you run and we open a demo project that looks like your own work. Every feature, no card needed.
The price, the orders, the invoices and the margin sit on the same job as the drawings and the programme, so there is no separate spreadsheet to keep up to date.
Step 1 of 5
An estimate is trades and lines, each your cost plus a markup on the line, the trade or the whole job. Bring in your price list or your QS’s spreadsheet, or let SiteBot draft the lines from your drawings, priced from your own rates and past jobs, for you to check.
Step 2 of 5
The client gets your estimate on your letterhead, never your costs or markups, and accepts it on their phone with a signature. Once accepted it is locked, and it becomes the job’s quote on the Cost Tracker.
Step 3 of 5
Raise a purchase order and send it to the supplier, who approves it from a link. Every invoice on it draws it down, and BuildersAI refuses one that would take more than is left.
Step 4 of 5
Drop the week’s PDFs and photos in together. Each one is read for you, filling in the supplier, invoice number, net, VAT, reverse charge and CIS deduction, and waits for you to check it and mark it ready to pay.
Step 5 of 5
Tick the lines of the accepted estimate and signed change orders, and draw a percentage or an amount from each. It shows what is agreed, what is on earlier invoices and what is left, so nothing is billed twice.
Also on the money side
Overview
For each job: tasks done and late, the quote, what has been spent, what is still to draw on orders, the forecast margin, what has been invoiced and what the client has paid.
It answers from your own drawings, documents, programme and site records, in the web app and on the phone. Before using any of the 18 tools that change something, it reads the change back to you.
Ask it about the job
It drafts the work
It does the reading
And if your company already uses Claude, you can connect it to BuildersAI and ask it to do the same, as you.
If your company uses Claude, connect it to BuildersAI and ask it to read and update your projects for you: the programme, the site, the documents and the money.
It works with any AI app that can add a custom connector (the industry name is MCP), including Claude in the browser, the Claude desktop app and Claude Code. For your company’s owners and admins, once one of them switches it on.
Things you can ask it
Claude asks you in its own window before it uses a tool, and BuildersAI records every call it makes.
It sees and changes only what you can in BuildersAI. On a job whose costs you run, it can read the Cost Tracker and draft estimates, orders and change orders.
Anything that sends, signs off or announces waits for you in BuildersAI: an estimate, a purchase order, an email, the week’s plan. Nothing goes until you confirm it.
Every call is recorded in plain words, and a task’s history says “via Claude”. Your company decides whether it may read money and whether it may change it.
It cannot remove people, change anybody’s role, or touch your plan or billing. Turn it off and every connected app stops at once.

AI is only as useful as the information behind it. ChatGPT doesn't know what's happening on your site; BuildersAI does. Because your drawings, documents, photos, tasks and site activity all live in one place, SiteBot answers from your own job, not from the internet. Ask it questions, create tasks by speaking into your phone, and let it take care of the paperwork nobody enjoys.
Chief Technology Officer
Daniel leads engineering. He has spent nearly two decades leading software teams for household names such as Microsoft, JCB, the BBC and Sky. He turns site feedback into shipped features in days rather than months.
Founder & CEO
William grew up in a family that builds houses for a living and has been around construction sites for as long as he can remember. He has seen first hand that eight-figure sites are often run on WhatsApp and spreadsheets, and started BuildersAI to cut the invisible costs that take chunks of margin across a site. His aim is for BuildersAI to be the all-in-one site management platform built in the UK, for UK sites.
Construction Director
Luke has worked on construction sites across the globe and sees first-hand how sites operate on a weekly basis. As Construction Director he keeps BuildersAI honest about how sites actually run, shaping the product around real site workflows.

No. If they can use the apps already on their phone, they can use BuildersAI. Workers download it, log in and get on with the job.
Migration is straightforward. Upload your current plans, photos and certs and the app organises them into the right places. You can keep using existing tools alongside during the transition.
Yes. Price a job from your own rates, or have SiteBot draft it from your drawings and past jobs for you to check. The client signs it on their phone and it becomes the quote. Purchase orders, supplier invoices with CIS and month by month invoices to the client follow from it. BuildersAI does not take payments.
Yes. Your company’s owners and admins can connect Claude, or any AI app that takes a custom connector (MCP), and ask it to read and update your projects. It works as them, and anything that leaves the company waits for them to confirm it.
SiteBot answers from your own project: your drawings, documents, programme, diary and records, and the Building Regulations and health and safety law it has been given. A drafted estimate marks any line it cannot price as Needs a rate rather than guessing, and before SiteBot changes anything it reads the change back to you.
Yes. The app keeps working on site without signal. Photos, tasks and check-ins sync as soon as the phone is back online.
