The workflow, end to end

What goes in, what the AI does, what comes out, what your team gets back.

Input
Loan packet + applicant docs + policy + BSA/AML signals
Work
Summarize the packet, flag missing documents, triage BSA/AML signals, draft adverse-action language where required
Output
Reviewable loan summary, exception list, BSA/AML triage queue, draft adverse-action letters when applicable
Saved
25–45 minutes per loan packet

What this looks like in production

Loan processing is dense paperwork with regulator-mandated decision points — exactly the workflow shape AI handles well in an assistive architecture. AI drafts; the loan officer or underwriter approves.

In production: a loan packet enters the workflow. AI summarizes, flags missing or stale documents, triages BSA/AML signals, and drafts adverse-action language where applicable. The officer reviews everything material, edits or overrides where needed, and approves.

The governance discipline is OCC Bulletin 2023-17 third-party guidance — your AI vendor is a third party, and the bank's responsibility isn't diminished by using one. OCC 2026-13 model risk (April 2026) excludes generative AI from scope. NCUA supervises through existing third-party rules.

How we run it

  1. Two-week diagnostic with loan operations leadership.
  2. Build inside the real LOS, document repository, BSA/AML platform. Production from week 3.
  3. Pilot with a small named loan officer group.
  4. Tune BSA/AML triage against your historical patterns and BSA officer's calibration.
  5. Roll out to full loan ops with manager-led training. AI use policy + third-party AI vendor due-diligence in place.
  6. Audit trail: every document and decision archived with source data and officer edits.

Common questions

What does OCC 2023-17 require here?
AI vendors are third parties under the interagency rule. The bank must apply risk-based oversight across the third-party lifecycle. Use of third parties does not diminish bank responsibility.
Does OCC 2026-13 model risk management apply?
Mostly no for generative AI specifically — OCC 2026-13 (April 2026) excludes generative and agentic AI from scope. For traditional ML models, 2026-13 supersedes the prior SR 11-7 baseline.
What about BSA/AML — can AI make those decisions?
AI triages; humans decide. The architecture surfaces signals and routes to your BSA officer with a confidence score. The officer makes the SAR-or-not decision.
Will this affect adverse-action timing requirements?
If anything, it tightens compliance — drafts ready faster with regulatory content pre-checked. Audit trail shows generation, review, and send times.
What happens if AI drafts wrong adverse-action language?
The loan officer catches it during review. AI flags low-confidence drafts. Mistakes observable in the audit log; tuned monthly based on corrections.
