Delayed subs, dual-language & dictation for real listening on Netflix, YouTube, Disney+, Coupang Play & Viki. Hear it first. Hear it first. Read it after. SubLater delays subtitles (or hides them until you press a key), so you actually train your listening instead of reading along. Two training modes — Fixed delay (2.0s on the free tier; Pro adjusts it 0–5s, set 0 for real-time dual subs) or Reveal-on-demand (Pro; press S to check). Sentence tools — A/D jump between lines, R replays, L loops endlessly, P auto-pauses at sentence end. Dual-language subtitles — The translation appears below, in sync (YouTube can auto-translate; other sites use the subtitle tracks the player already offers). Learning Korean? Turn on Korean subtitles and English appears below (great for K-dramas). Stuck on a word? Just hover (NEW) — Instant definitions for 34,000+ English words, fully on-device. Detects phrasal verbs and idioms ("look it up", "be able to"). AI context notes explain why the word means what it means in this scene, powered by Chrome's built-in on-device AI (supported browsers). Note: definitions and phrasal-verb notes are written in Korean — this feature is built for Korean speakers learning English. AI context notes are in Korean on Korean-language browsers, in English otherwise. Prove you heard it (NEW) — Dictation (W): type what you heard and get instant scoring, two-stage hints, 0.7x slow replay, and a fanfare at 90+. Ladder replay (G): re-listen to one line in three steps — no subs, target language only, then translation. Missed lines are auto-collected for review (V) and Anki export. Full 14-day trial, free forever after — The app never locks you out. Subtitle delay (2.0s), dual subs, sentence navigation, hover definitions, and linking underlines stay free forever (dictation: 10/day, AI notes: 20/day, 50 saved lines). Pro ($8.99/mo or $49.99/yr): adjustable delay (0–5s), hide-until-reveal, phonetic line, unlimited dictation and AI notes, 5,000 saved lines, Anki export, phrasal-verb & idiom notes, ladder replay. Works on: Netflix, Coupang Play, Disney+, YouTube (with auto-translation), Viki. Plus: subtitle size control, mouse control bar, IME-independent hotkeys. Which languages? SubLater is built for Korean speakers learning English. Before you install, here is exactly what you get: · Any subtitle language — subtitle delay, hide-until-reveal, sentence navigation (A/D/R/L), auto-pause, saved lines. · English subtitles only — hover definitions, phrasal-verb notes, linking underlines, and the sound line (all written in Korean). · Dual subtitles pair your subtitle track with a Korean one — or with English if your subtitles are Korean. Other pairings (for example Japanese + English) are not supported yet, and the second line will not appear if the title has no Korean track. · Dictation scoring supports English and Korean only. No viewing data is ever collected. Subtitle text and saved lines never leave your device. The one thing that does leave your device is the email address you enter to unlock Pro — and only if you enter one. It is used solely to check whether that address has an active subscription, and we store it on no server of ours (it stays on your device until you disconnect it). If you never enter an email, SubLater never contacts our server or any third party. The only other requests it makes are to the streaming service you are already watching, to load that service's own subtitle files. SubLater is an independent product, not affiliated with Netflix, Coupang Play, Disney+, YouTube, or Viki. Each service requires your own subscription. ――――――――――――――――――― v0.18.0 update [The dictionary doubled] · Common words almost never come back empty now — 16,100 new Korean definitions, covering 96% of the top 50,000 subtitle words (was 63%). · Irregular past forms (flung, swung), accented words (jalapeño, café, señor) and forms like H2O and A.I. now resolve. [Idioms & set phrases: 139 → 3,100 (Pro)] · Phrases you cannot work out from the individual words: made a pass at · let him off the hook. · Now covering work, hospital, courtroom, school, travel, phone and sports situations that fill sitcoms. · Set conversational phrases too: good to know, makes sense, fine by me, what's up. · Objects in the middle are matched too — give me a hand and give her a hand resolve to the same entry. [Hover a word, hear how it sounds] · Every word popup now shows the sound as well: water → 워러r, comfortable → 컴f어r러블. · Ordinary words without a linking underline now show how they actually sound. [One spelling for one sound] · The hover popup and the sound line could spell the same phrase two different ways. how does this now reads 하러z이스 in both. · 17 spellings were corrected against our reference pronunciation data, including will you and what are you. [Subtitles that are not English or Korean] · Dictation gave a perfect score for an empty answer on Japanese and Chinese subtitles. It now says scoring is not supported instead. · The first hint revealed the whole answer. · Typing one correct letter auto-filled the entire line. · English pronunciation hints appeared on Spanish and French subtitles — linking underlines and the sound line now require an English track.
