The service
usum is a browser extension and accompanying API that generates AI summaries of publicly available YouTube videos. We provide the service on an "as is" basis and may change or discontinue features over time.
Acceptable use

- Do not abuse, overload, reverse-engineer, or attempt to circumvent the free-tier limits of the service.
AI-generated content
Summaries are produced by a Large Language Model and may contain errors or omissions. They are provided for convenience and are not a substitute for watching the source video. You are responsible for how you use them.
Subscriptions and refunds
