AML Suspicious Activity Reports: AI-Assisted Narrative Drafting for Defensible SARs
SAR narratives must explain why the activity is suspicious in language a regulator can act on. AI can draft narratives from transaction data and case notes — for BSA officer review and approval.

Section 1
The premise
SAR narrative quality determines whether law enforcement can act on the report; AI scaffolds the narrative against FinCEN guidance.
What AI does well here
- Draft narratives following the 'who, what, when, where, why, how' structure FinCEN expects
- Synthesize transaction patterns with case-specific context (KYC, prior activity, related parties)
- Maintain the calibrated language that distinguishes suspicious from confirmed
- Generate the supporting documentation index
What AI cannot do
- Make the determination of whether to file a SAR (that's the BSA officer's call)
- Substitute for the formal review process
- Replace the institution's policies and procedures for SAR filing

AI and AML SAR Narratives: Telling FinCEN Why This Activity Is Suspicious
Section 3
The premise
A SAR narrative needs the who, what, when, where, why, and how — in tight prose FinCEN's analysts can read in 90 seconds. AI can draft the narrative from transaction data and case notes, but the BSA officer's name goes on the filing.
What AI does well here
- Convert a chronological case file into the FinCEN-required narrative structure.
- Suggest the typology code that fits the activity pattern.
- Generate the related-parties section consistent with the case file.
- Draft the supporting documentation index.
What AI cannot do
- Decide whether the activity meets the SAR-filing threshold — that's BSA officer judgment.
- Replace the institution-knowledge that informs 'why we found this suspicious.'
- Predict whether FinCEN will follow up — they don't usually tell you.
