Rough notes in. Finished document out.

A quick look at the Assistant taking real, messy input and turning it into a clean, professional document — running entirely on local hardware.

How it works

Four steps. Nothing leaves the room.

01

You feed it a file

Engineer notes, a rough draft, a jumble of bullet points — whatever you've got.

02

The airlock screens it

Every file is fingerprinted and checked before the AI can read it. Anything suspicious is quarantined at the door.

03

The local model drafts

The on-premise AI turns your input into a finished, formatted document — in your templates, your way of working.

04

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.
