A private AI assistant that never leaves your building.
The Vexbuild Assistant turns messy day-to-day work — engineer notes, tender responses, reports — into finished, professional documents in seconds. No cloud. No internet. No data ever leaving your walls.

How it works
Four steps. Nothing leaves the room.
You feed it a file
Engineer notes, a rough draft, a jumble of bullet points — whatever you've got.
The airlock screens it
Every file is fingerprinted and checked before the AI can read it. Anything suspicious is quarantined at the door.
The local model drafts
The on-premise AI turns your input into a finished, formatted document — in your templates, your way of working.
You review & approve
Everything is a draft. Nothing sends itself. You stay in control, and every action is logged.
What it does
Built for real, messy work.
Not a chatbot. A focused tool that does specific jobs, reliably, on your own kit.
Rough notes → finished docs
Turns scrappy input into professional, formatted documents in seconds.
Understands the mess
Typos, slang, jumbled notes — it reads real-world input the way a human would.
100% on-premise
Runs on a local AI model on your own machine. Your data never leaves the building.
Modular workflows
Add new jobs any time — reports, tenders, quotes, certificates, summaries.
Human in control
Everything is a draft. Nothing sends automatically. You always have the final say.
Full audit log
Every action and every refusal is on the record, ready for you to review.
Security by design
Locked inside a security harness.
This isn't AI bolted on as an afterthought. Every install is wrapped in layers built to keep it contained, controlled, and accountable.
Read-only reach
It can only read the documents you feed it — nothing else on your system.
Injection blocked
Prompt-injection attacks are caught and logged before they ever reach the model.
Document airlock
Files are screened and fingerprinted before the AI can touch them. Suspicious files are quarantined.
Drafts only
It can only write drafts. Nothing sends, saves, or acts on its own — ever.
Everything logged
A complete audit trail of every action and refusal, on the record.
Certified handover
Every deployment passes our own stress and security test suite before you get the keys.
Pricing
Fixed prices. No hourly rates. No surprises.
