About

SurfLexAI transforms your regular web browsing into a language acquisition tool. Simply double-click any word on a webpage or PDF to hear it in context, receive an accurate definition, and store the term with its original sentence. An integrated SM-2 spaced-repetition algorithm reviews saved vocabulary at the optimal moment before you forget. Master words through seven distinct modes, including flashcards, quick reviews, tests, AI writing feedback, listening exercises, chat roleplay, and grammar lessons. It supports seven languages, is free to use indefinitely with an optional Pro tier, and a mobile application is in development.
