Legislative change intelligence
Billy tracks every version of every bill across Congress and the states, then shows the exact words that changed, with a summary that cites its source. For the lawyers and lobbyists paid to catch the one clause everyone else missed.
FEDERAL · 50 STATES · DC · TERRITORIES
Assessment of agricultural land
SEC. 4 · IC 6-1.1-12.1-4.5
The credit under this section shall not exceed may not exceed twenty-five thousand dollars ($25,000) eighteen thousand dollars ($18,000) for each taxpayer eligible applicant per assessment year, and applies to assessment dates after December 31, 2026 December 31, 2025.
Lowers the deduction cap to $18,000, down from $25,000, narrows eligibility from any taxpayer to “eligible applicant,” and pulls the applicability date forward one year.
A single word moves a fiscal note by millions. Shall becomes may. A definition quietly widens. An effective date slips to “upon passage.” By the time the change surfaces in a floor report, the amendment is already three versions old.
Reading every version of every bill by hand does not scale. Billy does the reading, and hands you only the delta.
The pipeline
Every introduced, committee, and enrolled print, in every chamber, pulled the moment it posts. Nothing you track goes stale.
A precise redline down to the punctuation, aligned section by section, holding steady even when the print shop reflows the page.
An evidence-grounded summary that cites the exact page, and a memo you can hand to a client without re-typing a word.
What you get
Change log, full redline, and side-by-side, synchronized. Click any claim to open the evidence panel on the exact page of the source. Annotate a span, set an alert, hand it off. The diff is where the work happens, so it is where we invested.
SEC. 12 · “small business” means
a business entity that employs fewer than fifty (50) one hundred (100) individuals on a full-time basis in the state.
You don’t ask what’s in HB 1003. You ask what’s pending against IC 6-1.1-12.1. Billy inverts the view: a page per code section, every pending bill touching it, and a collision alert when two of them amend the same language.
The model language you drafted just surfaced in a bill you weren’t tracking. The amendment you killed last session just reappeared in SB 412. Billy fingerprints every provision and tells you when your words move.
Introduced to enrolled as a genealogy: every version, action, and sponsor, linked to its redline, and exportable as the history memo you’d otherwise assemble by hand.
Export the redline as a Word document with real track-changes marks and a Bluebook citation in the header. It lands in the client’s inbox looking like you drafted it.
Tag each bill support, oppose, monitor, or seek-amendment, with a note and a history. Then generate the weekly client roundup from the record you’re already keeping.
Effective dates, applicability, and retroactivity extracted into a compliance timeline, with crossover and hearing deadlines surfaced as “action needed by” chips.
Grounded, not generated
Legal work cannot run on a summary you can’t check. Every sentence Billy writes is anchored to a span in the source PDF. Click a claim, the evidence panel opens to the exact page. No sentence stands without its citation, so nothing you repeat to a client is something you have to take on faith.
“Lowers the deduction cap to $18,000, down from $25,000.”
Coverage
Federal, all fifty states, DC, and the territories share one schema from day one. The model never assumed a single statehouse, or a single print shop’s idea of what a bill looks like. We light up jurisdictions as our partners need them.
Live polling starts with Congress and Indiana, plus the states our design partners work. Turning on another is a config line and a backfill, not a rebuild.
