Use Cases
Loan Underwriting Automation
What is an AI loan underwriting agent?
AI loan underwriting agents execute the underwriting file end to end: classifying documents, extracting financials, evaluating them against your credit policy, and drafting the credit memo. Every step lands in an audit trail examiners can follow, from source page to final decision.
Loan underwriting automation with audit trails
A commercial loan package: financial statements, tax returns, credit reports, appraisals, entity documents, guarantor information. An underwriter must cross-reference all of it, apply policies, calculate ratios, and synthesize a credit memo. MightyBot does this in minutes with full evidence trails.
The Problem
Manual underwriting creates three compounding failures.
Slow — complex commercial loans take days of data extraction,
spreadsheet building, and memo writing.
Inconsistent — two underwriters weight factors differently,
apply policies with different interpretations, miss different data points.
Unscalable — volume increases force a choice between headcount,
turnaround, or analysis depth. Financial statements arrive in different formats.
An LLM wrapper hallucinates on the numbers that matter most.
Format variability
Financial statements from Big Four, regional CPAs, internally prepared — all different
Multi-document cross-referencing
Tax returns, credit reports, appraisals, entity docs must reconcile
Policy application
DSCR, LTV, concentration limits vary by loan type and borrower
Ratio calculations
Financial ratios from scattered data across multiple documents
Credit memo assembly
Hours of manual synthesis into an auditable format

-
Credit memo generation
Structured memos with every data point linked to source via evidence pointers. Ratios shown alongside source line items. Ready for credit review.
-
Exception routing
Loans requiring judgment routed with full context. Underwriters focus on credit decisions. Edge cases handled.
Production Metrics
Measured in MightyBot production deployments.
Policy application is deterministic: the same file and the same policy produce the same result.
Before vs After
Loan underwriting automated end-to-end. Days become minutes.

FAQ
Frequently Asked Questions
What is an AI loan underwriting agent?
An AI loan underwriting agent is software that performs the mechanical steps of underwriting (document classification, data extraction, ratio calculation, policy checks) under a bank's own credit policy, and assembles the result for an underwriter's decision. It executes policy; it does not improvise credit judgment.
How does loan underwriting automation maintain an audit trail?
Every extracted value keeps a pointer to its source page, every policy evaluation records which rule fired and why, and every human override is logged. The result is a decision file an examiner can replay end to end.
How does MightyBot handle different financial statement formats?
The Data Engine and FRS canonicalization process statements from Big Four firms, regional CPAs, internally prepared financials, and tax-basis compilations. Different formats, same structured output.
Can MightyBot enforce our specific underwriting policies?
Yes. Your criteria are authored in your credit team's language and evaluated deterministically. MightyBot ships with standard lending policies and layers your institution-specific rules on top.
What happens when a loan requires a policy exception?
The file is routed to the appropriate reviewer with policy triggers, extracted data, evidence pointers, and any conflicting information already assembled.
Does MightyBot support SBA and government-guaranteed loans?
Yes. SBA SOPs, USDA requirements, and other government program criteria can be encoded as policies with the same deterministic enforcement and evidence trails.
How long does deployment take?
Production deployments typically start within weeks. Integration, policy configuration, and document training can happen in parallel with your existing LOS in place.
What does an examiner-ready audit trail include?
Every decision includes a why-trail linking directly to policies and source data. Examiners can move from any memo value to the original source page and extracted evidence.
