Watch with subtitles. Keep the words you hear.

Open your first video

How does learning from videos work?

The player does not bring videos of its own. It plays what you open, and turns the subtitles into something you can tap.

1. Open a video. On Android, open a stream link from another app with “Open with” and choose repeat.cards, or add the link on the Videos tab. A video file from your phone or computer opens too.
2. Pause on a subtitle and tap. Tap a word, or several words in a row for a phrase, and the translation opens under the video. One button translates the whole line.
3. Save it and train it. The word goes to your inbox with its translation, then becomes a flashcard that spaced repetition brings back before you forget it.

One phrase, from a subtitle to a card

Here is the whole trip for a phrase heard in a video.

What the player does for you

• Subtitles from the stream or your own file. Use the subtitles a stream carries, or load an .srt or .vtt file. Its encoding is detected for you, so an old file in a local encoding reads correctly.
• A shift to sync them. If a subtitle file runs early or late, move it in small steps until the lines match the speech.
• The whole line at once. Translate the full subtitle when a single word is not enough, and step back to the previous line or on to the next one.
• Unknown words underlined. Words that are not on your known-words list are underlined, so you can see what is new in a line at a glance.
• On Android and in the browser. The player is in the Android app and on the website. On a computer, the keyboard works too: Space to pause, the arrow keys to move between lines.

What it plays

repeat.cards has no catalogue and suggests no channels or services. It plays streams (HLS links, .m3u8), M3U lists of streams and common video files, and keeps a history of what you opened on your device so you can return to where you stopped. Use it with videos you are allowed to watch.
