Private LLM for financial institutions

An AI tool that summarises, searches and drafts like the public ones, installed in the bank’s data centre, with permissions by org structure and an audit log compliance can inspect.

An IT officer walks a server aisle between “Installed in our data centre” and “Audit log · 1,204 queries today”. Banks & financial institutions
“Staff quietly use ChatGPT to summarise customer documents because it’s fast. Compliance finds out, bans it, and everyone goes back to doing it by hand.”

The problem

Credit officers, compliance and branches have documents to read every day: borrowers’ financials, a new circular, an operating manual revised every quarter. A public tool summarises them in a minute, so some staff use it quietly until compliance finds out and bans it, because customer data cannot leave the bank under the regulator’s rules or under PDPA.

That leaves the bank with two bad options: let people use it quietly and risk a leak, or ban it and watch everyone go back to reading by hand.

How we solve it

We install a language model in the bank’s data centre, on your own servers or in a cloud account the bank controls, on Kubernetes run by your own infrastructure team. Staff sign in with their bank account through Active Directory and use it to summarise documents, search the rules and draft memos the way they would with a public tool, with everything staying inside the bank’s network.

Permissions follow the org structure, so a credit team sees only the customers in its own portfolio, and every question goes into an audit log compliance can open. We hand over with penetration-test results and auditor documentation, following the approach the bank’s compliance and security teams set.

The system summarises and drafts. Loan approvals, replies to customers about their accounts and anything with a financial effect remain decisions for staff with the authority the rules give them. The system sends nothing out of the bank on its own.

How it runs

Work comes in from
  • Borrower documents from the LOS
  • Circulars and operating manuals
  • Questions from branches and the call centre
  • Documents in SharePoint
What the AI does
  1. Check permissions by org structure
  2. Summarise and search with references
  3. Draft memos and answers
  4. Record every question in the audit log
Where it lands
  • One-page summary to the credit team
  • Answers to branch staff
  • Drafts for the authorised officer to check
  • Audit log for compliance

Before and after

Before
After
Staff use a public tool quietly; compliance has no idea what data went out
Everyone uses the same tool in the bank’s data centre, with an audit log
Summarising one borrower’s financials takes half a day
The financials are summarised with the follow-up questions in minutes
A rule changes and branches phone head office all day
Branch staff type the question and get the rule that applies at once

What you get

Who gets what

Business owner

Staff get the tool they want without going behind anyone’s back, and the bank can answer every auditor’s question about where the data is and who touched it.

IT director

Installed on Kubernetes in your own data centre, sign-in through Active Directory, no external API calls, penetration-tested and handed over with auditor documentation.

The team using it every day

Credit officers and branch staff stop reading hundred-page documents by hand, and stop worrying that wanting to work faster will get them in trouble.
