Noiz

Noiz is a consumer AI application focused on summarising YouTube videos and extracting transcripts. It is distributed through a browser extension, web tools, and mobile apps, and its core utility is rapid consumption of long-form video content through timestamped summaries, transcript generation, and multilingual support. The legal entity disclosed in policy and app materials is Rational Expressions Inc., while Noiz is the public brand. The business runs on a freemium subscription model. Free tools attract users through low-friction access to summarisation and transcription features, while paid plans monetise higher usage and expanded functionality. Its direct customers are individual users such as students, researchers, professionals, educators, and creators who want to compress research and learning workflows around YouTube and related content formats.
