LingoPlayer Coming Soon
AI SubTranslate — play local videos with subtitles pre-translated by your own AI.
About
LingoPlayer is an Android video player that translates subtitles for you. While you watch a local video, it pre-translates external subtitle files (SRT, ASS, VTT) or in-video text subtitles line by line using an AI provider you connect — a local AI model, OpenAI, Claude, or Gemini — and caches the results so playback in your chosen language stays smooth. You bring your own AI; LingoPlayer runs without any server of ours.
