Most major video, social and streaming platforms via the yt-dlp library. If a site stops working temporarily, we patch the extension within 24-48h.
We use AssemblyAI's Universal-3 model for transcription (95%+ accuracy on clear English) and GPT-4o-mini for translation. Quality is excellent for clear speech; expect lower accuracy on heavy accents, music-heavy clips or whispered audio.
Never. We download audio temporarily, transcribe it, then delete everything within minutes. We never store the video file, never log what you watch, and never share your data with third parties.
Chrome, Edge, Brave, Opera and any Chromium-based browser. Firefox is on the roadmap. Safari is not currently supported.
