The problem

The volume is public. The provenance is not.

LegiScan states that "keeping up to date and tracking the 175,000+ bills each year can be a daunting task". Its live counter reports 207,800 pieces of legislation tracked from Congress and the 50 state legislatures in the active biennium.

Most teams still hold a slice of that in a shared spreadsheet. The spreadsheet records a status. It does not record the URL the status came from, the moment it was read, or the person who checked it. When someone asks how you know a bill moved, the answer is a screenshot.

A spreadsheet tracking bills across jurisdictions, annotated to show what it is missing: a source URL, a capture timestamp, and a note that manual upkeep is easy to miss and hard to maintain.

How tracking works

01-04

Every field carries its source

Bill ID, chamber, sponsor, status, committee assignment and version each record the URL they were read from and the time they were read.

A Federal Register notice on EPA air quality standards beside the equivalent Matterwire record, with a source link and capture time attached to every field.Three amended versions of a California Senate bill, each timestamped, next to a version-history timeline marking when each change was introduced, amended, and passed.Bill and regulation listings from the California legislature, UK Parliament, French Journal Officiel, and EU Official Journal converging into one unified Matterwire record.Matching single-use-plastic-packaging language highlighted across California, EU, UK, and Canadian filings, converging into one Matterwire record listing all four sources.

Every field carries its source

Traceability

What a tracked bill looks like

This is the full record, not a summary of it. The source URL resolves to the state legislature. The verifier ID identifies the person who checked the fields against that page.

Where Matterwire sits

Between a spreadsheet and a six-figure contract.

Tracking by hand costs you the provenance. Enterprise incumbents keep the data in their own dashboard and will not publish an accuracy figure or a price.

Works for a while, but hard to maintain.
