Hover any subtitle word on Netflix to see its definition, synonyms, and AI-powered context. Supports your own free Groq key. Thesara brings vocabulary context directly to your Netflix subtitles. Hover any word while watching and a tooltip appears with a definition, synonyms, and an AI explanation of what the word means in that specific scene. The video pauses while you read, then resumes the moment you move on. No new tab. No Googling. No lost scenes. WHAT YOU GET Definition and part of speech from the Free Dictionary API Synonyms displayed as quick-reference pills Scene-aware AI context powered by Groq, explaining not just what a word means but what it means here, in this moment, in this show LEARNING THAT STICKS Dictionary definitions are forgettable. Context is not. Thesara shows you a word exactly when it matters, inside the scene that made you curious about it. That is how vocabulary actually builds. FREE TO USE A shared AI quota is included at no cost. No account, no setup, nothing to configure. If the daily shared limit is reached, you can connect your own Groq API key in under two minutes. Groq's free tier provides 14,400 requests per day at zero cost, no billing required. PRIVACY FIRST Thesara requests one browser permission: storage. No browsing history is collected. No words you hover are logged. Your API key, if added, lives only on your device and is sent only to Groq. There is no analytics, no telemetry, and no data shared with anyone. Open source.
