Local AI · Based in London
Own the brain that runs your back office.
It reads, extracts and files your documents the second they arrive — on a box you own. Nothing leaves.
Every other AI wants your data. Crucible runs on yours.
Every invoice you hand to a cloud AI is a lease payment on someone else’s computer — and they can change the terms, retire the model, or read your books whenever they like. Crucible is the other option: a box in your building, your data on your network, the capability yours to keep. You own it.
WELCOME
Welcome to Crucible AI.
your back office, given a brain
A private AI agent that lives on a box in your building and goes to work the moment a document arrives. Step inside.
RUNS LOCAL
Frontier-grade AI that never leaves home.
your data stays in the building
Everything runs on hardware you own, on your own network — no cloud to send your documents to, nothing leaving the premises. The capability of the big models, kept entirely in-house.
IT DOES THE WORK
It doesn't just chat. It gets the work done.
reads, extracts, checks, files
It opens the document, pulls out the numbers and names, checks them against your records and files a clean result — hands-on work on every item that lands, not answers you still have to action.
BY DESIGN
Map the process once. It runs forever.
plan · intake · extract · review · file
And it works to the exact steps your office already follows. Lay them out once and Crucible runs them on every document that arrives — stopping only to ask when something doesn't look right.
THE RESULT
The backlog, cleared. Your team, freed.
from inbox to filed record
The pile that used to eat a person's week now runs quietly in the background — clean records straight into Sage, Xero or your ERP, and the manual keying gone for good.
Book a scoping callThe full toolkit
One agent. The whole back office.
You anchor on the one job where your data can’t leave the building — then the same on-prem agent expands across everything else the office does by hand.
Intake to record
A document arrives → it classifies, extracts, validates and files. Only the exceptions wait for a human.
Custom pricing, per project
Computer vision — inspection
A second pair of eyes on the line. Anomaly detection on the cameras you already have — running on-prem.
Document review & risk
Read a long contract or report → surface the clauses, risks, gaps and deadlines that matter.
Knowledge lookup
Ask your own files. The right clause, record, spec or precedent in seconds — answered with its source.
Summarisation
Long or many documents → the gist that actually matters, without reading every page.
Voice & dictation
Speak instead of type: site notes, case updates and records dictated and filed as structured data — often the single biggest time-saver.
Research & discovery
Supplier, material, market, case and precedent research — gathered and summarised privately, with its sources.
Document generation
Draft the outbound document from a template and your own data — ready for a human to sign off.
Media generation
Carousels, short videos and presentations — generated in your own brand, on your hardware, with nothing sent to an outside model.
Slides & report decks
Board, client and review decks, built straight from your own data — formatted and ready to present.
Custom software & sites
Build the internal tools and small sites you keep needing — invoice generators, dashboards, customer portals, booking forms, calculators, even a microsite — bespoke to your process and run on your hardware.
Data analysis & insight
Analyse your own data → the trends, anomalies and quiet leaks no one had time to look for.
Data cleanup & reconciliation
Dedupe, normalise, validate and match records across systems that were never meant to talk.
Quoting & estimating
An enquiry or spec becomes a priced, on-brand quote in minutes — pulling your rate card, past jobs and margins, ready to send.
Forecasting & credit control
Predict the cash position, flag who to chase first and forecast demand — from your own ledgers and order book, not a generic model.
Anomaly & fraud detection
Flag duplicate invoices, changed bank details, mandate fraud and out-of-pattern transactions before the money moves.
Report & compliance assembly
Auto-build the recurring return or the pack a regulator demands, from the records you already hold.
Regulatory horizon-scan
Track the rules and standards that change in your sector → a one-page, plain-English list of what's new and what to do.
Security scans & maintenance
Scan your systems and network for vulnerabilities, misconfigurations and unpatched software, watch the logs for anomalies, and handle the routine updates, backups and health checks — all on-prem, nothing phoning home.
Inbox & support triage
Sort, route and draft replies across a shared inbox or ticket queue — the backlog stops growing.
Complaint & feedback analysis
Triage complaints, reviews and survey responses into themes — what's breaking, and how often.
Recruitment & CV screening
Parse CVs, score and shortlist against the role, and draft the job ad — on candidate data that never leaves. You make every call.
Onboarding & HR admin
Post-offer to day one: contracts, right-to-work checks, inductions and training records assembled in minutes, audit-ready and GDPR-clean.
HR helpdesk
Answer staff questions on policy, leave and benefits straight from your own handbook — on employee data that stays in the building.
External chatbot — front of house
A customer-facing assistant on your site: answer enquiries, qualify leads and book jobs from your approved content. Nothing about your customers leaves.
Every one of these runs on the same agent, on the box in your building. Start with the job where your data can’t leave — then turn the rest on as you need them.
COMPUTER VISION
Computer vision, in action.
every part, checked on camera
Point it at the line and it watches every unit go past — matching each part to spec, reading the labels and serials, and flagging the cracks, dents and wrong-fit pieces the moment they appear. Thousands of items an hour, every one checked the same way.
THE OUTCOME
Catch the defect before it ships.
no scrap, no recalls, no escapes
The cracked casting, the mislabelled box, the out-of-spec batch — stopped at the machine, not discovered by your customer. Fewer recalls and returns, less scrap and rework, and a quality record you can actually evidence.
Book a scoping callMeet Crucible
Watch it read a document — and file it.
It reads what arrives, pulls out the numbers and names, checks them, and files a clean record. Here’s a single invoice, handled.
How Crucible reads and files a document
Extracted · validated
Example: an anonymised supplier invoice.
Why local
Three reasons it has to be yours.
It keeps working, whatever the vendor decides.
The model your cloud workflow runs on was never yours — vendors retire models on their schedule, and access has been cut off for every customer at once. On your own hardware, no memo three time zones away can stop your back office.
Your most sensitive documents never leave.
Invoices, case files, patient records, designs under NDA — the documents you can’t hand to a public API are exactly the ones Crucible reads, on hardware you control. The work gets done without the exposure.
Frontier-grade results on the work you actually do.
Reading a document, pulling the numbers, filing the record — local models now match the cloud giants on exactly this. You get the capability where it counts, running quietly in a box in your own building.
How it works
From inbox to filed record. Automatically.
Crucible runs one relentless loop on every document that arrives — so the pile stops growing.
- 01
A document arrives
Invoice, order, case file, claim or statement — by email, PDF, scan or portal.
- 02
It reads and classifies it
Crucible works out what the document is and which workflow it belongs to.
- 03
It extracts the data
Numbers, names, codes and dates — pulled out clean, with no manual keying.
- 04
It flags what it isn’t sure of
Anything it isn’t confident about waits for a person. You sign off the exceptions; everything else flows.
- 05
It files the record
Structured data pushed straight into Sage, Xero, Proclaim or your ERP.
- 06
You get your time back
The intake that used to eat a person’s week runs quietly in the background.
Prove it to your auditors
Your data never leaves the building.
Every document is processed on hardware on your premises. There are no egress routes to third-party AI — and your IT or compliance team can audit the traffic to prove it. We encourage it.
The product
A managed appliance. You don’t maintain it.
We handle the hardware, the model, the updates and the support — remotely. Your team turns on a workflow; they don’t babysit a GPU.
You own the hardware
A box in your building, on your network — not a tenancy on someone else’s server.
Keeps pace with your busiest week
Process ten documents or ten thousand on the same box — it scales with your volume, and no one has to babysit a GPU to do it.
Tuned to your documents
Customised to your invoices, part numbers, precedents and chart of accounts — not a generic model.
Auditable by your team
No egress to third-party AI. Your IT or compliance team can verify the traffic for themselves.
Sectors
Built for the firms the cloud locked out.
We start where the data wall is highest. The loop is the same underneath; only the documents and the regulator change.
Manufacturing
Designs, specs and pricing bound by NDAs and export-control rules — the kind of data that's safest on hardware you own.
Law firms
Privilege and SRA confidentiality make sending a client file to a third-party AI a professional-indemnity problem.
Accountancy
You hold a client’s entire financial life. Casual cloud processing is a risk you can’t take — and MTD only adds volume.
Healthcare
Special-category patient data, active ransomware targeting, and an absolute duty of confidentiality.
Construction
NDA’d contract documents, the UK’s largest SME sector, and sites where connectivity can’t be relied on.
The company
Hold us to our word.
We design a private AI agent around your documents, deploy it on hardware you own, and run it for you — scoped to a result we agree up front. We’re early, and we say so: no inflated logos, no invented numbers. What we offer instead are commitments written into the engagement, not the marketing.
A delivery date in writing
Scope and go-live agreed up front, on paper — not an open-ended engagement.
Scoped to an outcome, not hours
We agree the workflow and the result it has to deliver up front — a specific job done, not an open-ended retainer.
No lock-in, ever
It runs on your hardware, with your model weights, on your own network — no cloud dependency and no kill-switch. The capability you buy is yours to keep.
The questions sceptics ask first.
We already have an ERP or document system.
- Crucible doesn’t replace Sage, Xero or Proclaim — it feeds them clean, structured data from the documents that never made it in. No rip-and-replace.
What if the AI gets it wrong?
- Every extraction has a confidence threshold. Below it, the document waits for human review. You see everything it touches and sign off the exceptions. It’s a filter, not a black box.
How do we know the data really stays on-site?
- Your IT or compliance team can verify the network traffic — there are no egress routes to third-party APIs. You can audit it, and we encourage it.
We have no IT team to run it.
- You don’t run it. Crucible ships as a managed appliance: we deploy, monitor, update and support it remotely. You simply turn on a workflow.
Are we ever locked in to Crucible?
- No. It runs on your hardware and your model, on your own network — independently of any cloud and of us. No kill-switch, no vendor you can’t leave. The capability you buy is yours to keep.
Stop renting your business’s brain. Own it.
Tell us what arrives on your back office. We’ll scope the first workflow — on your documents, on your premises — and reply within one working day.
