Liar's Ledger — Receipts for Politicians

Read a news article about a politician? Liar's Ledger checks their actual voting record against what the article says they stand for.

Click "Scan This Page" on any political news article. In seconds, Liar's Ledger:

• Identifies every current and former member of Congress mentioned in the article
• Extracts the key policy claims made about each politician
• Pulls their real legislative record — bills they sponsored, cosponsored, roll-call votes, and interest group ratings
• Delivers a verdict: does their record support, contradict, or give mixed signals on what the article claims?

Every verdict cites specific bills, vote positions, and ratings. No opinions. No editorials. Just the public record.

HOW IT WORKS

Liar's Ledger uses two independent AI models (Claude and Mistral) to read the article and extract who said what about policy. Then it cross-references those claims against official data from Congress.gov, GovTrack, and VoteSmart. A third AI pass evaluates whether the politician's actual record supports the claim — and explains why, citing specific legislation.

DATA SOURCES

All data comes from official, non-partisan public sources:
• Congress.gov — Sponsored and cosponsored legislation (API provided by the Library of Congress)
• GovTrack — Roll-call vote history
• VoteSmart — Interest group ratings from organizations like the NRA, ACLU, AFL-CIO, and Chamber of Commerce

WHAT IT DOESN'T DO

• Does not run in the background or track your browsing
• Does not collect your name, email, or any personal information
• Does not store the articles you scan
• Does not access your location
• Only activates when you click "Scan This Page"
