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.

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
