BentoSub

BentoSub is a privacy-first AI subtitle tool that never uploads your video. Audio is extracted locally in your browser, so only ~30MB of audio reaches our servers instead of your full video file — deleted automatically after processing. Built for creators who work with mixed-language content. Japanese-English, Korean-English, Chinese-English code-switching is handled accurately, including loanwords and technical terms that shouldn't be translated. Drop in your video, choose source and target language, get bilingual subtitles in minutes. Edit in the browser, export SRT.
