Private AI for Estate Agents: Customer Data That Stays in the Branch
A negotiator who pastes a tenancy file into a public chatbot to summarise it has just sent a tenant’s references and a landlord’s bank details to a company the agency never assessed. Private AI puts the same assistant in the branch.
£500 per month for the software and the hardware rental. You rent the machine — you don’t buy it.
Private AI for estate agents is a ChatGPT-style assistant running on a dedicated machine in the branch, so tenancy files, sales files, AML records and landlord correspondence can be drafted from and summarised without customer data reaching a third-party provider. Portals and CRM stay as they are; we install and support it.

Private chat, document spaces and assistants on one machine in the branch. Tenancy files and AML records never leave the office.
Cloud Agents for Enquiries, Local AI for the Paperwork
Viewing requests and valuation enquiries suit a hosted agent; tenancy files, AML records and vendor correspondence suit a machine in the branch. Most agencies run both.

The Ban Does Not Work. The Alternative Does.
Staff at estate agents who need a letter drafted quickly are already using a chatbot. A blanket ban moves that out of sight; it does not stop it.

The Data in the Folder Is Not the Agency’s to Share
An estate agency’s files are unusual in one way: almost none of the personal data in them belongs to the agency. Tenants’ references and bank details, landlords’ instructions and account numbers, vendors’ circumstances, buyers’ mortgage positions, and the identity documents collected because HMRC supervises estate agents for anti-money-laundering — all of it is held on trust for someone else. Pasting a tenancy file into a public chatbot to get a summary shares all of it with a provider none of those people agreed to.
Private AI for estate agents keeps the convenience and drops the sharing. The assistant runs on a machine in the branch. Sales and lettings files, tenancy agreements, AML customer due-diligence files, landlord correspondence and templates go into document spaces on it, and every summary, draft and answer is produced in the building. Nothing is sent to an AI provider, and the agency’s retention policy keeps applying because the files never left.
The listing copy negotiators wanted the chatbot for is still there, done better: viewing notes in, a first draft in the branch’s house style out, with the material-information items National Trading Standards expects checked against the file. So is the harder work: what a tenancy says about subletting, a file summarised before a renewal conversation, an AML file checked against the branch’s own list for missing documents — without the assistant verifying anyone or making the risk assessment, which a person does.
Rightmove, Zoopla, OnTheMarket and the CRM are not connected; drafts go back by a person pasting them. Sign-in is the Microsoft 365 or Google Workspace account staff already have. We install the machine in the back office, import the first branch’s files and train negotiators and managers on what it does and what it is not for.
Lettings managers ask one more thing: what about the photographs? Property photos, tenant ID scans and inventory images are uploaded to the private chat like any document, and like any document they stay on the machine in the branch. Nothing about an image makes it leave the building, and nothing about an ID scan makes the assistant able to verify it — a person still does that.
One Private AI Machine, Three Tools On It
Everything runs on the one machine in the branch, and your team log in with the accounts they already have.
A private AI chatbot for the whole team
A ChatGPT-style assistant on your own machine. Staff ask questions, upload documents and images and work through drafts, and none of it leaves the building.
Document spaces
Files and correspondence organised into spaces. Search, summarise and compare across hundreds of documents, with a citation to the page every answer came from.
Custom assistants
The monthly report, the standard memo, the routine check — built around your workflows and running on the same machine, covered by the support arrangement.
| Document | What the branch asks for | What stays where |
|---|---|---|
| Viewing notes and photos | A listing draft in house style; material-information gaps listed | On the machine, in the branch |
| Tenancy agreements and renewals | What the tenancy says; a summary before renewal | On the machine, in the branch |
| Sales files and vendor correspondence | A summary; the answer to a buyer’s question, cited | On the machine, in the branch |
| AML customer due-diligence files | Which documents are present and missing, against your checklist | On the machine, in the branch |
| Landlord instructions and management agreements | What was agreed; the clause on repairs | On the machine, in the branch |
| CRM and portal listings | Not connected — a person pastes drafts back | Your existing systems |
From a Branch Manager’s Call to a Private Assistant in the Back Office
Weeks, not months. Multi-branch agencies start with one branch and one job and widen from there.
A call with the branch or director
Sales, lettings or both, how many staff, which paperwork goes first. We specify the machine from that.
Install and import
The machine goes on the branch network. Sign-in connects to your Microsoft 365 or Google Workspace. Files, templates and correspondence for the first team are imported into spaces.
Train the team, then support
We train negotiators and managers on what it does and what it is not for. Updates, model upgrades and support follow, from the people who installed it.
Where Local AI Is the Wrong Answer
We would rather lose the enquiry than the trust. Three things we tell every prospect before they sign anything.
It will not make you compliant by itself
No product can make a business UK GDPR-compliant on its own. What private AI does is remove the hardest question from the assessment — where the personal data goes. Lawful basis, retention and staff conduct remain yours.
It is slower than the big cloud models
Open-weight models on a single machine are capable for summarising, drafting and answering questions about your own documents. For frontier reasoning on hard, novel problems, the largest cloud models are still ahead. That is the trade.
It is a weeks-long install, not a sign-up
A cloud agent is live in days. Local AI needs the machine specified, delivered, installed on your network and your documents imported. Weeks, not months — but not tomorrow.
Private by Construction, Not by Policy
Nothing leaves the building
Open-weight models, documents and chat history all live on the box. No third-party AI processor and no restricted transfer for the AI step.
Your sign-in, your access list
Single sign-on with Microsoft 365 or Google Workspace. You decide who has access with the tools you already administer.
Never trained on your content
Your documents and conversations are not used to train or improve any model. The models arrive trained and stay that way unless you ask.
Installed and supported by us
Hardware, installation, training, updates and support from one team, with a data processing agreement covering the support access you grant us.

Private AI for Estate and Letting Agents: Common Questions
What is private AI?
AI that processes your prompts and documents on hardware you control instead of on a provider’s servers. With ours, the model, the chat history and every uploaded file stay on a machine in the branch. Nothing is sent to an outside service to produce an answer.
Is a private LLM as good as ChatGPT?
For everyday work — summarising, drafting, extracting, answering questions about your own documents — it is capable and most offices are happy with it. It is somewhat slower, and the largest cloud models are still ahead on hard, novel reasoning. That is the trade for keeping data in-house.
Can negotiators use it for listing copy?
Yes, and it is usually the first thing they do: viewing notes in, a first draft in your house style out, with the material-information items checked against the file. The agent still confirms the facts before it goes on the portal.
Why is a private AI chatbot better than the chatbot they already use?
Because the files a branch holds belong to tenants, landlords, vendors and buyers, and a public chatbot sends them to a provider none of those people agreed to. On a machine in the branch, nothing leaves the building — and staff get the same assistant, closer.
Can we upload tenant ID scans and inventory photos to it?
Yes, and they stay on the machine in the branch like any other document. The assistant can read a scan and list what a file contains; it does not verify anyone’s identity and does not make the AML risk assessment. A person does both.
Does it connect to our CRM or the portals?
No. Rightmove, Zoopla, OnTheMarket and your CRM stay exactly as they are. Documents and correspondence are exported into spaces on the machine; what the assistant drafts is pasted back by a person.
Can it help with AML files?
As an assistant, yes. A custom assistant can go through a customer due-diligence file and list which documents are present and which are absent against your own checklist. It does not verify identity and it does not make the risk assessment; a person does.
How much does Local AI cost?
£500 per month for the software and the hardware rental. The dedicated machine is rented to your business, not sold: you never buy the hardware. It is installed in your building and runs the private chat, document spaces and assistants. Local AI is for business customers only.
