AI subtitles for streaming video — in sync, cached free on replay, or hear it translated aloud live in your language. Watch any video in your language. SubVibe adds AI subtitles to a video and keeps them perfectly timed to the player, with a karaoke highlight that lights up each word as it's spoken — and it can speak the translation aloud, in real time, while you watch. Bring your own API key (OpenAI, Anthropic, or Google). Everything runs directly from your browser to the provider you choose — no SubVibe servers, no account, no tracking. Translated videos are cached on your device, so replays are free. Two ways to follow a video • Subtitles — reads the video's own caption track and translates ahead of the playhead, so lines land exactly on time. Show a second language beside the original for learning. • Live Translate — hear the video in your language as it plays, powered by Google Gemini. You bring your own key; casual everyday listening is low-cost, and it works across 70+ languages. More of what it does • Karaoke word highlight — follow along word by word as it's spoken, built for language learners • Make it yours — style presets plus full control of font, size, color, and position; drag the subtitles anywhere. Styling and karaoke also work on the video's own original captions, with no translation and no cost — handy for learners, or just to resync captions to the picture. • Bring your own key — nothing is billed by SubVibe; you pay your provider directly, usually cents an hour • Sync dock for time-shifted live streams; recorded videos stay frame-exact automatically • Local library and cache — every translated video is saved on your device; replays are instant and free • Cost meter — see what today's watching actually cost Where it works SubVibe runs right inside the player on the streaming services, public broadcasters, and online-course sites it supports, with more on the way. On every other page it stays completely inactive. Privacy Your keys and your cache never leave your device. Subtitle and audio text is sent only to the AI provider you configured, with your own key. No analytics, no tracking, no middleman. Full policy: see the Privacy link on this page. Made with care by an independent developer. Version numbers honor the maker's father — that's why they start at 1330.
