Watch Jupiter and Lasteekraan with Estonian captions and free English translations together. Watch Jupiter and Lasteekraan shows with Estonian subtitles and English translations at the same time. Estonian appears in white and English underneath in yellow. English captions are prepared ahead, including while paused. The popup shows preparation progress and lets you adjust subtitle size and position. Both languages remain visible in fullscreen, and completed translations are saved on your device. HOW TO USE 1. Open a show on jupiter.err.ee or lasteekraan.err.ee and enable its Estonian captions. Some shows call this track Vaegkuuljad. 2. Click Jupiter Kaks in Chrome’s toolbar, read the caption-sharing notice, and enable English translations. 3. Allow a few seconds for captions to prepare, then press Play. FREE TRANSLATION No account or personal API key is required. Caption text, including upcoming captions, is sent to the University of Tartu’s Neurotõlge service when English is enabled. New installations start with English off. The public service may have temporary limits, and machine translations can make mistakes. Works with shows that already have selectable Estonian captions. It does not create captions from audio. Casting, video-only picture-in-picture, and cross-origin embedded players are not supported. Jupiter Kaks is an independent project, unaffiliated with ERR or the University of Tartu. Support: https://github.com/muhammednagy/jupiter-kaks/issues
