Score: 6.0/10 (Innovation: 6, Technical: 5, Documentation: 7, Utility: 7)

Rhino is a Chrome extension that provides AI-powered contextual explanations for selected text on webpages, distinguishing itself by analyzing full page context rather than offering generic dictionary definitions. It's interesting because it implements a BYOK (Bring Your Own Key) model supporting multiple AI providers with failover logic, addressing privacy concerns while delivering real-time, streaming explanations.

Target audience: students, researchers, non-native-speakers, professionals
