In development
You should be able to understand an active area of legislation within minutes.
The problem
Congressional staff routinely have to understand a long bill, amendment, or new version on a markup or floor clock. Existing redline tools can show which words moved, but they stop before answering which changes affect a particular member, committee, or district. Commercial summaries try to close that gap with generated prose, then warn users to verify the result against the bill—the exact work the summary was meant to save.
The approach
Winnow treats legislation as structured text. It computes exact diffs from official legislative XML, identifies changes such as funding amounts, deadlines, eligibility language, new authorities, and repeals, and ranks those changes at the provision level for a particular user. Claims are assembled from the bill’s own language, figures extracted by code, and fixed sentence patterns. When the text cannot support a conclusion, Winnow points to the relevant language instead of inventing one.
The same underlying diff can compare a bill with current law, an amendment with the bill it changes, or House and Senate versions of the same idea. A provision-first record could eventually follow an idea across bills and Congresses, show related sections that may be affected by a change, and alert staff when language relevant to their portfolio moves.
Where it stands
Winnow is in product development. The current design establishes the trust boundary—verify rather than generate—and the core jobs for congressional staff, advocates, and constituents. The next work is to turn that design into a reliable end-to-end system: acquiring and normalizing legislative text across both chambers, measuring the quality of provision matching and relevance ranking, and testing whether the resulting view changes what a user can understand under real time pressure.
