NeonLingo is an AI language learning extension for Chrome and Edge that translates words as you read, saves them to a wordbook, and brings them back until they stick.
About NeonLingo
What Is NeonLingo
NeonLingo is a browser extension from Taaakooo Tech LLC that turns ordinary web pages into language practice. Install it, select a word you don't know, and the word translation appears in place while the word lands in your vocabulary list. No separate study app, no flashcard session to schedule.
Most vocabulary tools ask you to stop reading and drill. NeonLingo goes the other way: you learn words while reading, inside the news articles, documentation and forum threads you already open. Saved words come back highlighted on later pages, so you meet the same word in several contexts before you sit down to review it.
The limits are worth knowing before you install. The free plan caps the vocabulary list at 200 words and gives you 200 interpretations a month through the Google Translate engine. Better translation models, phonetic transcription and custom highlight colors sit behind Premium. The extension runs in desktop Chrome and Edge. There's no mobile app.
Getting Started
- Install NeonLingo from the Chrome Web Store or the Microsoft Edge Add-ons store, then pin the icon to your toolbar.
- Open the popup and choose the language you're learning. Page language detection happens on its own.
- Select any unfamiliar word while browsing. The translation opens in a small panel and the word is saved without a second click.
- Sign in if you want your wordbook and settings on more than one device. The same account turns on FSRS flashcards.
- Open the wordbook to review what you've collected, or enable bilingual reading to swap part of a page into your target language.

Key features
Instant Word Translation on Any Page
Select a word and NeonLingo shows the meaning in a panel next to it. The free plan uses the Google Translate engine; Premium adds DeepL and AI models that read the whole sentence, which matters when a word has four possible meanings. No copy, no paste, no tab switching.
Automatic Wordbook With Cross-Page Highlighting
Every lookup is saved to your vocabulary list along with the sentence it came from. When the same word appears on another site, NeonLingo highlights it, and hovering shows the meaning again. This is the part that separates it from a dictionary extension: the words follow you around the web.
Bilingual Reading Mode
Instead of translating a whole page, NeonLingo swaps a portion of the words into the language you're learning while the rest stays in your native language. You can adjust the foreign-language proportion and the number of highlighted words from the popup. The idea borrows from comprehensible input, where new words sit just above your current level.
DeepL and AI Translation Engines
Premium unlocks DeepL and AI translation with phonetic transcription for each word. The AI engine picks the sense that fits the sentence rather than listing every definition, so you spend less time guessing which meaning applies. Premium includes 1,000 uses a month; Premium+ removes the cap.
FSRS Flashcards and Cross-Device Sync
Sign in and your wordbook, settings and review history sync across devices. FSRS scheduling decides when each word comes back based on how well you recalled it last time. Words you keep forgetting return sooner; words you know drop out of the queue.
Word Groups, Filters and Learning Journey
Version 2.6.4 added custom groups you can drag to reorder, a default group for new saves, and filters by topic, part of speech, encounter count or source site. Missing topics and parts of speech fill in automatically. The Learning Journey view charts vocabulary growth, review trends and activity by subject.
Pros and cons
Pros
- Learning happens during reading you already do, so there's no extra session to skip.
- Automatic saving catches words you would otherwise look up and forget within a minute.
- Cross-page highlighting creates repeated exposure in real contexts, which is hard to fake with a word list.
- Sentence-aware AI translation on Premium resolves meaning correctly more often than word-by-word lookup.
- FSRS scheduling is a proven review method, and sync keeps the queue consistent across a laptop and a desktop.
Cons
- The free plan stops at 200 saved words and 200 interpretations a month, which a heavy reader will hit in two or three weeks.
- Bilingual reading only makes sense when the page is in your native language, so it does little for sites already written in the language you're learning.
- Desktop Chrome and Edge only. Anyone who reads mostly on a phone gets no help here.
- Subscription pricing is per month with no lifetime option, and the yearly discount is billed upfront.
Frequently asked questions
It translates words you select on any webpage and saves them to a vocabulary list. Later, it highlights those words on other sites and schedules them for review with FSRS flashcards.
