Subly

Click any subtitle. Instantly understand it.

Subly turns the subtitles you're already watching into clickable, scene-aware explanations. Hit a word you don't know? Click it — right in the subtitle — and a compact card explains it instantly, without pausing your show or stacking a second subtitle track on screen. What makes Subly different: ★ Scene-aware, not just a dictionary. Subly reads the subtitle line the word appeared in (and the lines around it) and tells you what the word means in THIS moment — not a generic definition. Names, slang, and idioms included. ★ Never interrupts your show. Subly overlays invisible, clickable hotspots on the subtitle your streaming site already draws. It never hides, covers, or pauses the video — if Subly does nothing, your subtitle is exactly as it was. ★ Works where you watch. Netflix, YouTube, Prime Video, and Hotstar — plus a companion desktop app that brings the same clickable subtitles to films you play in VLC. ★ Instant on repeat. Answers are cached, so a word you've seen before returns in a fraction of a second. ★ Hear it spoken. One tap pronounces the word aloud. ★ Private by design. No account, no sign-up, no personal data, no ads, no tracking. Install it and start clicking. How it works: 1. Click any word in the subtitle while you watch. 2. Subly sends it (with the surrounding lines) to a scene-aware AI. 3. A card appears in place — meaning, pronunciation, part of speech, and what it means right here. Keep watching. Great for language learners who want words explained in context, and for anyone who hits the occasional unfamiliar word in a show or film. Subly is free while in beta.
