PromiseLedger
A fact-tracking app that records every campaign promise with a timestamp and source, then prompts candidates (and challengers) to update its status — keeping scorecards live through Election Day and beyond.
Voters and civic educators who want accountability beyond campaign season
- Promise-by-promise tracker with source links and dates
- Browser extension that flags promises on any candidate's website
- Shareable scorecards designed for social media and classroom use
- Local-down-to-federal coverage with bookmarking by issue
Implosion stories like Platner's usually expose how little verifiable track record existed; PromiseLedger gives voters a tool to spot weak claims before the next collapse.
Category exists and has sustained attention — PolitiFact built an entire promise-tracking product (Trump-O-Meter → MAGA-Meter) and GovTrack has run 20+ years, but no clear signal of users downloading/installing a dedicated app rather than visiting fact-check sites.Which fact-checking organizations provide the most comprehensive promise tracking ↗GovTrack.us: Tracking the U.S. Congress and the White House ↗
Market is crowded with near-identical products: VowTrack, Spurna (AI-powered, launching Aug 2026, same premise), PromiseWatch, PoliTruth, promisetracker.ca, and PolitiFact's MAGA-Meter already serve this exact use case.Spurna — AI-Powered Political Accountability & Campaign Promise Tracker ↗VowTrack - Political Promise Tracking ↗PoliTruth - Track Every Promise ↗PromiseWatch - Tracking Political Promises ↗
Civic accountability tools are almost universally grant-, donation-, or institution-funded (PolitiFact is Poynter non-profit, GovTrack is non-profit, Spurna is student-built). No evidence of consumers paying for promise-tracking subscriptions; willingness-to-pay from voters is weak.PolitiFact ↗VowTrack - Political Promise Tracking ↗
Useful across any election cycle and policy debate
Technically straightforward — web scraping + LLM extraction + simple DB and UI are all commodity — but the real cost is sourcing/verification, candidate engagement, and editorial trust, which is why Spurna is taking a year to build.Spurna — AI-Powered Political Accountability & Campaign Promise Tracker ↗
