About Rule Atlas
Open infrastructure for encoded law. We build machine-readable encodings of statutes, regulations, and policy rules to serve as ground truth for AI systems.
Our mission
Our mission is to make legal rules machine-readable, verifiable, and accessible to everyone. We're a fiscally sponsored project of the PSL Foundation.
What we do
Atlas
Open platform for exploring encoded law. The Archive holds 53 USC titles, 570+ IRS guidance documents, and 48 states. Atlas brings together source documents, RAC encodings, and validation results.
RAC
Rules as Code DSL for encoding statutes with citations, temporal versioning, and tests. Purpose-built for legal encoding.
AutoRAC
AI-powered encoding pipeline with 3-tier validation. Automated statute encoding with CI testing, oracle validation, and LLM review.
Team
Rule Atlas is led by Max Ghenis, who also founded PolicyEngine. We're an open-source community project and welcome contributors from all backgrounds — developers, policy experts, legal researchers, and anyone passionate about making rules more transparent and accessible.
