Roadwatch is a web app for investigating public spending on road construction, built on the principle of evidence before conclusions. For any street in Toronto or Montréal, or any supplier followed across federal, provincial and city records, it pulls what governments publish (contracts, non-competitive awards, lobbying, 311 complaints, permits, audits and winter weather) and stores it as documents that can be cited. It then runs arithmetic checks and procurement indicators, and can have an AI model read every page, with any finding whose quotation isn't actually in the source thrown out automatically. Findings are presented as leads for human review, each with an innocent explanation and a next step, and people work on them together through shared discussions, statuses and search across all cases, by exact words or by meaning. It runs on your Mac or hosted online with MongoDB Atlas, and the code is public on GitHub.
