About Legislation Lemur
Legislation Lemur is a civic data platform focused on making the United States Congress easier to understand.
The platform combines congressional data, legislative activity, voting records, committees, and bill summaries into a single experience designed around clarity, transparency, and usability.
Rather than adding commentary or interpretation, Legislation Lemur focuses on helping users navigate public information through cleaner interfaces, clearer organization, and accessible explanations.
Every feature follows the same principle: reduce complexity without changing the underlying facts.
Public information should be easier to navigate.
Government information is public, but it is often difficult to navigate.
Legislative text can span hundreds of pages. Congressional activity is distributed across multiple systems and sources. Many existing tools assume familiarity with legislative procedures and terminology.
Legislation Lemur was created to lower those barriers through thoughtful design, neutral presentation, and modern data visualization.
The goal is not to tell people what to think. The goal is to help people understand what Congress is doing.
The name "Lemur" reflects curiosity, persistence, and exploration—qualities shared by both the data work behind the platform and the civic mission it supports.

AI-assisted summaries are a starting point, not a replacement for source text.
Legislation Lemur includes AI-assisted summaries to make complex legislation easier to navigate.
Summaries are generated from official bill text and structured congressional data, then organized into consistent sections that highlight purpose, major provisions, key actions, and legislative status.
These summaries are intended as a starting point rather than a replacement for primary sources. Users should consult official legislative text when evaluating specific policy details.
The goal is to improve accessibility and comprehension while preserving neutrality and source transparency.
