HerculesAI (formerly Zero Systems) announced today (14 May) the release of the Rule Library, which it says expands its AI functionality beyond outside counsel guideline (OCG) enforcement to full-spectrum compliance.
The Rule Library is an AI-powered engine that converts OCGs and internal guidelines into large language model (LLM)-enforceable checks that run automatically on work in progress (WIP) and pre-bills.
“We’ve expanded beyond OCG enforcement to full-spectrum compliance, capturing internal standards, partner preferences, and historical deduction patterns, not just what’s written in the guidelines,” Alex Babin, CEO of HerculesAI, told Legal IT Insider.
When billing compliance is framed only as enforcement of OCG rules, law firms are missing a major piece of what causes deductions. End-to-end compliance requires adherence to a wider set of rules found in alternative sources like internal guidelines and historical deduction patterns.
These internal sources could include firmwide entry standards, dictating how narratives should be written, or they could include rule sets for specific clients and matters that the billing team has created to augment OCGs, highlighting what language to use versus avoid.
The HerculesAI Billing Compliance platform leverages an assembly of Large Language Models, which have learned from a detailed ontology of legal billing rule types, to automatically turn text into structured rules that contain an accurate classification, relevant attributes, and the full context of enforcement logic that results in a one-click fix recommendation.
The system flags violations in real time, suggests one-click fixes, and delivers ‘audit-ready’ analytics, which Hercules AI says helps reduce revenue leakage by as much as 50 percent.
“Our goal is simple: turn billing compliance from a burdensome cost center into a profit lever,” said Babin. “HerculesAI clients are realizing 24x return on investment and millions in annual value by letting our AI-workers review hundreds of thousands of invoice line items against extensive, complex rules – many extracted automatically from Outside Counsel Guideline documents. The new Rule Library packages that capability, delivering higher realization rates and faster work-to-cash cycles.”
Its available now as part of the HerculesAI platform, which integrates with leading finance systems such as Aderant Expert and Elite 3E.
