# Rolko – Learn languages from real content

Rolko is a language-learning web app and browser extension that turns supported subtitles, transcripts, and webpage text into interactive practice. Learners can look up pronunciation and meaning, save useful words, track vocabulary, and review them with spaced repetition.

Rolko supports normal webpage text, selected subtitle workflows, supported transcripts, vocabulary tracking, and spaced-repetition review. It does not currently perform OCR on text baked into images or video pixels, and it is not affiliated with Netflix, YouTube, or Language Reactor.
