Readlang is a reading tool for language learners who want to work with native content. Readers can select words or phrases in text and webpages for translations, then use AI explanations that account for context. Collected translations can be practiced with spaced-repetition flashcards that prioritize useful words, or exported to Anki. Reading material can come from articles, books, pasted text, uploaded files, or webpages imported using a browser extension or bookmarklets. Its video player supports full transcriptions, including transcripts users upload and sync with YouTube videos. A popup dictionary is available in the Web Reader, while the online eReader has a sidebar dictionary. Readlang lists web, Android, iOS, and extension platforms, but says it has no native mobile apps; its web app can be added to a mobile device’s home screen. The free plan includes unlimited single-word translations, but allows 10 phrase translations and 10 context explanations per day. Premium costs $6.00 USD per month or $48 per year; Premium Plus costs $15.00 USD per month or $120 per year.
