## Overview

NeonLingo is built around the problem that most vocabulary tools stop working the moment you close them. Translation extensions let you look a word up, and then you forget it a week later because nothing brings the word back. NeonLingo closes that loop: it translates any word you select as you read, saves it automatically to a wordbook, and then re-highlights that word on every subsequent page where it appears. Review happens inside the browsing you were doing anyway rather than in a separate study app.\n\nThe extension offers two learning paths. On foreign-language pages, you get on-demand translation with the sentence context intact, so you can infer meaning rather than memorise a definition. On native-language pages, Bilingual Reading swaps a handful of words into your target language, deliberately choosing words one step above your level — the comprehensible-input (i+1) principle associated with linguist Stephen Krashen, which the product leans on explicitly. The rest of the sentence stays in your own language so context carries the new word.\n\nNeonLingo runs on Chrome and Edge and covers 30 languages. The free plan includes selection translation, a 200-word wordbook, cross-site highlighting and up to 200 interpretations a month; Premium raises the wordbook to 500 words, adds whole-sentence AI translation and unlocks FSRS spaced-repetition flashcards that sync across devices. New users get a 7-day Premium trial, and the product also offers document translation.
