Kuaizhuan Subtitle is an online AI workstation for audio/video transcription and multilingual subtitle production, connecting speech recognition, subtitle reflow, translation, editing, video burn-in, and export in one workflow. It is designed for video creators, subtitle producers, and people who need to turn recordings into editable text, with recognition and translation presented for Chinese, Cantonese, English, Japanese, Korean, and many other languages. The system can re-segment lines using surrounding context to improve subtitle length and reading rhythm.
After generation, subtitles can be edited online with customized font effects and layouts, then burned into a video or exported as MP4, SRT, ASS, LRC, TXT, VTT, or MD. Using the workstation requires an account login and audio or video content, while the resulting transcript, line breaks, and translation still need review by someone familiar with the source language. The official page labels its real-time shared workflow as forthcoming, so that collaboration feature should not be treated as currently available.
