Just ask

Query the database conversationally. Every answer is grounded in real legislation, with links back to the source.

What CuraLex gives your AI

Twelve tools. Every answer traced to a bill number and an official link.

Find bills

Search 2.1M bills by topic or number — or enumerate an entire cohort, page by page.

search_legislation · list_bills

Read one, or a hundred

Sponsors, subjects, milestones, committees, companions, hearings, votes — one bill or a whole tracking list.

get_bill · get_bills

Read what it actually says

Pulls the bill's own text from the legislature and converts it, so your assistant can quote the statutory language instead of paraphrasing a summary.

get_bill_text

Follow it through committee

What is parked before a given committee right now, and everything ever referred there.

search_committees

Count across states and years

Exact cross-tabs in one call: who passed what, when, and which state moved first.

count_bills

Follow the legislators

Who sponsors a policy nationally, how a member has actually voted, and who broke with their party.

search_people · get_person · get_roll_call

Watch what's moving

What changed this week, and which hearings are scheduled next.

activity

Know the limits

Coverage, vocabularies and caveats up front — so the assistant qualifies answers instead of guessing.

describe_corpus

Try asking

Once connected, prompts like these run against the live database:

  • “What was the latest health care bill passed in Wyoming? Pull it up and explain what it does.”
  • “On Texas HB 20 (2025), how did the vote split by party — and who crossed the aisle?”
  • “Are any hearings scheduled on AI bills in the next two weeks?”
  • “Who were the top sponsors of health-related bills in Maryland this past year?”
