Real-Time Captions for Any YouTube Video
Accurate transcription for every YouTube video — even when auto-captions are wrong, missing, or in the wrong language.
Better Than YouTube's Auto-Captions
YouTube's built-in captions miss words, struggle with accents, and aren't available on every video. Google reports that only about 60% of watch time has auto-captions enabled, and accuracy drops significantly for non-English content. TranscribeAudio uses OpenAI's Whisper-based speech recognition — which achieves a 4.2% word error rate on English benchmarks — to transcribe any YouTube video in real time, directly in your browser.
Watch Foreign-Language Content with Live Captions
Watching anime, K-dramas, foreign news, or language courses on YouTube? TranscribeAudio transcribes spoken audio in 57 languages including Japanese, Korean, Chinese, Spanish, French, and German. Use it for immersion learning or just to follow along with content that doesn't have subtitles.
Follow Tutorials Without Rewinding
Coding tutorials, lecture recordings, and how-to videos move fast. TranscribeAudio shows live captions in a floating overlay so you can read what was said while keeping your hands on the keyboard. No need to pause and rewind every 30 seconds.
Works on Shorts, Live Streams, and Music
TranscribeAudio captures audio from any YouTube page — regular videos, Shorts, live streams, premieres, and YouTube Music. If it plays audio in your Chrome tab, it can be transcribed. YouTube hosts over 800 million videos, and TranscribeAudio works with all of them.

よくある質問
Does this work on YouTube videos without captions?
Yes. TranscribeAudio captures audio directly from your browser tab and transcribes it independently of YouTube's caption system. It works on any video regardless of whether the creator uploaded subtitles or YouTube generated auto-captions.
Is TranscribeAudio more accurate than YouTube's auto-captions?
