LidSubFlow

Full-sentence YouTube subtitles with a searchable list, plus translation of subtitles, titles and on-screen text.

YouTube's auto-generated captions cut sentences into pieces: a few words appear, vanish, and you are left to stitch the meaning together. LidSubFlow joins those pieces and shows them on the video as complete, readable sentences. WHAT IT DOES • Full-sentence subtitles: whole sentences instead of rolling fragments. Drag and resize the caption box. • Searchable sentence list: every sentence with its timestamp next to the video. Search a word, click a sentence, jump to that moment. • Subtitle translation: translate each sentence into one of 20 languages, original and translation stacked. • Title translation: video and card titles in your language. • Shortcuts: Alt+S toggles the subtitles, Alt+L hides the list. PRO FEATURES • Screen translation: reads text inside the video picture (slides, signs, screenshots) and places the translation right next to it. • Links and QR codes: makes web addresses and QR codes shown on screen clickable. • Custom appearance: font, color and opacity for subtitles and screen translation.

WHO IT IS FOR Language learners, anyone watching lectures and talks in another language, and everyone who prefers watching with subtitles. PRIVACY No account needed. Text recognition for screen translation runs on your device, in your browser; video frames are never uploaded. Only text is sent to the translation service.
