A new free tool, noiseevidence.com, has been launched to help tenants generate evidence for noise complaints. Built and shared on Hacker News, this no-registration tool supports 27 US cities with accurate noise ordinances, creating real-time recordings and professional PDF reports suitable for court. A key differentiator is its 100% local processing; no data is uploaded to servers, ensuring privacy.

The creator built it out of frustration with existing subscription-based tools. This matters because it democratizes access to legal-grade evidence for landlord-tenant disputes, removing cost and technical barriers. By automating day/night noise limit detection and providing court-ready documentation, it empowers tenants to effectively navigate housing disputes without compromising their personal data.
