What Is Tammy
Tammy is a specialized artificial intelligence system developed by the U.S. Securities and Exchange Commission to support enforcement investigations. It uses natural language processing and machine learning to scan corporate filings, press releases, and other public disclosures for potential violations of securities laws. The system is designed to identify patterns, anomalies, and high-risk signals that human analysts might miss when reviewing large volumes of documents SEC.
The SEC has described Tammy as part of a broader effort to modernize its enforcement capabilities using advanced data analytics. The tool helps staff efficiently prioritize cases by flagging companies or individuals whose disclosures contain unusual language, inconsistencies, or references to high-risk activities. Tammy does not replace human judgment but serves as a force multiplier for enforcement attorneys and examiners Forbes.
How Tammy Works
Data Ingestion and Processing
Tammy ingests structured and unstructured data from EDGAR filings, enforcement actions, and other public sources. The system parses documents to extract entities, events, and relationships, then applies classification models to surface potentially problematic statements or omissions. By automating the initial review phase, Tammy reduces the time analysts spend on document sorting and basic fact extraction.
Pattern Detection and Risk Scoring
The platform uses pattern recognition to detect recurring language or behavior across multiple filings that may indicate misconduct. It assigns risk scores to entities and topics based on the frequency and severity of flagged content. These scores help enforcement teams focus their resources on the most promising leads, improving the speed and precision of investigations SEC.
Tammy’s Role in SEC Enforcement
Use Cases and Impact
Tammy has been applied to cases involving potential insider trading, accounting fraud, and misleading disclosures. The tool helps identify companies or individuals whose public statements conflict with internal records or regulatory expectations. By surfacing these conflicts early, Tammy supports the SEC in building stronger cases and reducing the risk of overlooking critical evidence.
Integration with Existing Systems
Tammy operates alongside other SEC analytics platforms and enforcement databases, integrating findings into the agency’s broader case management workflow. The system is designed to work with existing legal and investigatory tools, allowing staff to incorporate AI-generated insights without disrupting established procedures. This integration supports a more data-driven approach to enforcement prioritization and case development Forbes.
