A bank used an AI agent to put new clients' records into one standard format, and staff review what the agent is unsure about. A credit union can use the same pattern for the papers in a loan file. Start with ten closed files with the names removed.

## Why
Northern Trust, a bank, unveiled the agent on Nov 9, 2026. It converts years of client records from many formats into the bank's standard format. Data preparation took two and a half weeks before. The bank reports it now takes three days. That number covers preparation only. The bank tested the agent on data with client names removed. Staff review the output and handle the uncertain items. A credit union has the same kind of step. A mortgage file or a business loan file arrives as pay stubs, tax returns and statements in many formats. A processor types the numbers in by hand.

## Steps
1. Pick one loan type where staff type numbers from papers by hand. Mortgages and member business loans have the most papers.
2. Time that step on your next ten files. Count the errors that underwriting sends back.
3. Ask your loan system vendor whether it already has a feature that reads documents. A tool you already pay for comes first.
4. Take ten closed files. Remove names, account numbers and Social Security numbers.
5. Have the tool read the papers and fill in your standard income and asset sheet.
6. Have the processor who did the original work compare the two results and mark every error.
7. Bring the error count and the minutes saved to the chief lending officer.
8. Send the tool through vendor review before it touches a live file.

## What data may go in
Test only with closed files that have names, account numbers and Social Security numbers removed. A live member file goes only into a tool that passed vendor review and does not learn from what users type.

## Who checks the output
The loan processor checks every number against the source paper. The underwriter makes the decision. Tell the board that AI sorts the papers and a person decides the loan.

## Cost and time
The report gives no cost. The bank built a custom system with Microsoft. A credit union starts with a feature of its loan system or an AI tool it already pays for. About one day for the first ten files.

## The rule to check
The tool reads and sorts papers. A person decides the loan. If AI ever takes part in a loan decision, the member must get the real reasons for a denial. The credit union must also test for fair treatment. Every vendor that touches member data needs a review.

## What can go wrong
The bank reports a first-pass quality score above 96%, so staff still find and fix the rest. One wrong income number can change a loan decision. The processor checks every number before underwriting sees the file.
