SurfLexAI - AI-Powered Translation & Language Learning Assistant

Double-click any English word to translate and save it. Review with flashcards, quizzes, and writing practice.

Tired of memorizing words that vanish the next day? You looked them up, maybe wrote them in a notebook — but honestly… 🧠 You forget by tomorrow The word you checked today is gone tomorrow. Without spaced repetition, nothing sticks — and your effort goes to waste. ✍️ You can't use them in a sentence You know the meaning, but when it's time to speak or write, you freeze. Recognizing a word and using it are not the same thing. 🤷 Translations feel out of context The dictionary lists ten meanings — which one fits this sentence? You end up with awkward, wrong guesses. SurfLexAI breaks that loop while you read: • Double-click any word on a webpage — get a context-aware translation, part of speech, and idiom detection powered by Gemini. • Save it in one click with the full sentence. Saved words are highlighted automatically wherever they appear. • Review with SM-2 spaced repetition: flashcards, quizzes, fill-in-the-blank, matching, and writing practice — the right word at the right time. 💬 Ask AI while you learn • Stuck on a word? Ask a follow-up question right from the tooltip — usage, grammar, nuance, all explained in your language. • Practice tab: chat with an AI conversation partner on any topic, get instant error correction, and ask about anything in the conversation. • Roleplay scenarios — job interview, café chat, email writing — practice real situations, not just lists.
