By what you build
Most projects reduce to a handful of reusable patterns. Start from the one closest to your goal, then adapt.Legal Q&A chatbot
Answer statute and regulation questions with an assistant that quotes the section it relied on and links to the official source.
Ground an LLM or agent (RAG)
Retrieve the on-point statutory text, feed it to an LLM in your stack as context, and return citations instead of guesses.
Resolve and verify a citation
Turn a citation or an
actId into verified metadata and full text, and confirm a quoted passage is real before you ship it.Compliance obligation mapping
Map a control, policy, or obligation to the statutes and regulations that govern it, with a source link for every match.
Monitor corpus coverage and changes
Read
/statutes/coverage at runtime to know exactly what is queryable, and track how jurisdictions and section counts grow week to week.Compare a rule across states
Run the same query against multiple state codes and line up how each jurisdiction treats an issue side by side.
Enrich a citation database
Backfill an existing table of citations with canonical text, structured metadata, and official government links.
Add the corpus as an agent tool (MCP)
Expose statute search and retrieval to an AI agent as tools it can call, so it grounds itself in law on demand.
By who you are
Same corpus, different jobs. Here is what each kind of team tends to build, with a recipe to start from.Legaltech / SaaS builders
Embed statute search into a CLM, drafting, or practice-management product. Ground an in-app research assistant. Show the governing section next to a contract clause, with a link to the source.
In-house legal & compliance teams
Stand up an internal research tool over the US Code and CFR. Map company policies to the regulations behind them. Answer “what does the law say here” without leaving your own systems.
Law firms & solo practitioners
Build a first-pass research assistant grounded in statutes and court rules. Pull the exact section text into a brief or memo. Confirm a cited statute resolves before it goes out the door.
RegTech / compliance-monitoring vendors
Power automated regulatory checks against the CFR, the Federal Register, and agency guidance. Watch coverage grow to widen what you monitor. Alert customers when the underlying obligations shift.
GRC / IRM platforms
Show the actual statute or regulation text inside a risk questionnaire so answers are grounded, not from memory. Attach a citation to every control. Link each requirement to the law that drives it.
Due-diligence, KYC & investigations
Look up the licensing or disclosure rules that apply across a target’s states of operation. Compare a requirement jurisdiction by jurisdiction. Attach authoritative source links to a diligence memo.
Academics, policy researchers & journalists
Assemble a cross-state dataset of how an issue is regulated. Trace a rule from executive order to Federal Register to codified regulation. Cite primary law with a stable link every time.
Content & SEO teams / legal publishers
Generate accurate, citation-backed explainers grounded in the real section text. Enrich a citation index with canonical text and official links. Keep published references pointing at authoritative sources.
AI labs / model builders
Supply grounding data for legal RAG. Validate that model-generated citations resolve to real sections and quoted passages. Build evaluation sets from authoritative statutory text.
Government & civic tech
Make the law searchable for constituents in plain language. Cross-reference state codes, constitutions, and court rules. Link every answer back to the official government text.
Coverage expands weekly. Call
/statutes/coverage at runtime to see exactly which jurisdictions and corpora are queryable rather than hardcoding counts. See the Coverage matrix for the human-readable view.Start building
