Problem
English learners often struggle to understand new vocabulary and phrase usage when reading books or watching videos because traditional dictionaries provide isolated translations that lack contextual meaning, leading to inefficient study and slower development of English thinking.

Users tap any word to receive an instant definition that is automatically contextualized within the surrounding sentence, preserving the original nuance. The AI generates concise explanations and usage notes, helping learners acquire vocabulary and idiomatic expressions in situ. A built‑in smart review system reinforces newly learned items, while real‑time sync across devices ensures seamless study on web, iOS, and iPad. The service is delivered via subscription, granting unlimited contextual lookups and access to an extensive library of reading and video content.
