Free Korean subtitle generator
Drop a Korean-language video and Captionly transcribes it with AI Whisper, lets you fix names and proper nouns with a click, and exports SRT, VTT, ASS or a burned-in MP4. Detects Korean automatically. Free, in-browser, no signup.
Korean-language video has its own audience and its own search index. Captions extend the reach: they make Korean video accessible to sound-off viewers, indexable to search in Korean, and ready for downstream translation.
