Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Readlang is a browser-based language-learning application for learners who want to build vocabulary from authentic reading. Words and phrases in texts, websites, uploaded articles, books, and videos can be translated with a click, then saved for flashcard practice. Its online eReader, Web Reader extension, bookmarklets, customizable dictionaries, and video transcriptions support a reading-led workflow across the web. It also includes AI-powered context explanations and an AI conversation partner with writing corrections.
The free plan provides unlimited single-word translations, 10 phrase translations per day, 10 context explanations per day, and flashcard practice or export from specific books. Premium costs USD 6 per month or USD 48 per year, adding unlimited phrase translations, unlimited context explanations, 10 hours of audio storage, and high-quality voices for speaking words and phrases. Premium Plus costs USD 15 per month or USD 120 per year, with 200 hours of audio storage, voices for speaking whole texts, and GPT-4o AI. The published plans make Readlang suitable for trying the core reading workflow before paying for higher translation, audio, and AI limits.
Readlang’s focus is vocabulary acquisition through content rather than a broad course structure. Adaptive spaced repetition, Anki export, YouTube support, text uploads, and full video transcriptions give readers several ways to turn encountered language into review material. Access is provided through the web, mobile browsers, tablets, and a Chrome extension, so it suits learners who are comfortable studying in a browser. Choose Readlang for authentic reading, contextual translation, and vocabulary review; choose another app if native mobile apps, offline lessons, or verified speech practice are central requirements.
