About Lexora Companion
Welcome to the Lexora Companion Extension
Language learning shouldn't be confined to flashcard apps and isolated exercises. True fluency happens in the wild—when you are reading the news, writing an email, browsing Reddit, or watching your favorite creators on YouTube.
The Lexora Companion is a revolutionary browser extension that bridges the gap between structured learning and organic web browsing. Powered by an advanced, locally-hosted AI (Qwen2.5) and seamlessly synced with your personal Lexora portal, this extension transforms every webpage into an interactive, context-aware learning environment.
Whether you are studying English, Ukrainian, Greek, or Polish, Lexora integrates into your daily digital life to provide proactive writing assistance, passive vocabulary review, and deep linguistic explanations—without ever forcing you to leave the tab you are on.
🌟 Core Features & Capabilities
1. Lexora Writer: Your Active AI Writing Assistant
Stop second-guessing your grammar when typing in your target language. Lexora Writer acts as a proactive, intelligent coach that lives right inside your text boxes.
The Floating 'L' Button: Whenever you focus on a text area (like a comment box, email composer, or forum reply), a subtle glassmorphism "L" icon appears.
Instant AI Analysis: Click the icon, and our AI will analyze your drafted text. Within seconds, it provides a structured breakdown of your writing.
Corrections & Polish: You will receive specific grammar corrections (with explanations of why you made a mistake) alongside a completely improved, natural-sounding rewrite of your text.
One-Click Apply: Accept the AI’s suggestions and apply the polished text directly back into your input field with a single click.
Privacy-First: The extension is smart enough to ignore password fields, code editors, and search bars, ensuring your sensitive data is never processed.
2. YouTube Vocab Radar & Subtitle Mastery
Bring spaced repetition directly to your video consumption. Lexora makes YouTube the ultimate listening comprehension tool.
Passive Vocab Radar: Lexora silently scans upcoming YouTube subtitles for vocabulary you are currently learning. When a known word is about to be spoken, the video automatically pauses ~4 seconds beforehand, displaying a beautiful, non-intrusive alert.
Contextual Replay: The radar shows your translations and the full subtitle sentence. Click "⏪ Rewind 5s & Play" to hear the word pronounced in its natural, native context.
Smart Cooldowns: To prevent interruption storms, the Radar features a customizable cooldown (default 120 seconds) and allows you to "Skip this word" or "Disable for this video" instantly.
Interactive Subtitles: Click on any unknown word in a YouTube or Netflix subtitle track to instantly freeze the video and pop up a definition overlay.
Multi-Word Phrase Selection: Want to translate a whole idiom in a subtitle? Simply hold Ctrl (or ⌘) and click multiple words to select a phrase (e.g., "kick", "the", "bucket") to trigger a multi-word lookup, bypassing YouTube's strict text-selection blockers.
3. Webpage Shadowing (Pronunciation Practice in the Wild)
You don't need a dedicated app to practice speaking. Lexora lets you practice pronunciation using any text you find on the internet.
Select & Listen: Highlight any sentence on any website, click "🎤 Practice Pronunciation", and hear a flawless Text-to-Speech (TTS) rendering of the phrase.
Hold to Record: Press the record button and repeat the sentence into your microphone right from the browser.
AI Grading & Feedback: Your audio is instantly transcribed and compared against the original text. You receive a 0-100 score, with missed words struck through in red and mispronounced words underlined in amber. The AI also provides a personalized tip on how to improve your accent or rhythm.
4. Review in the Wild (Passive Spaced Repetition)
Why open a flashcard deck when the internet is already full of words? Lexora turns the web into a passive review session.
Color-Coded Highlights: As you read articles, Lexora quietly underlines words that belong to your active vocabulary list. The underline colors map to your Spaced Repetition System (SRS) state: Amber for new words, Green for learning, and Indigo for words up for review.
Hover to Reveal: Forget what a highlighted word means? Hover over it to trigger an SRS-aware tooltip. It will remind you how long ago you learned it and allow you to "Reveal" your stored translations (showing Ukrainian, Greek, Polish, and English simultaneously) with zero network latency.
5. Instant Grammar & Slang AI Explainers
Traditional dictionaries fail when it comes to context. Lexora’s AI explainers act as your on-demand linguistics tutor.
Explain Grammar: Highlight a confusing sentence structure and click "Explain Grammar." The AI will return exactly two concise sentences explaining the grammatical rule at play and why the sentence is built that way.
Explain Slang/Idiom: Not sure if a phrase translates literally? Highlight it and click "💡 Explain Slang/Idiom." The AI will categorize it (Idiom, Phrasal Verb, Slang, or Literal). It provides the true figurative meaning in your native language, the literal word-for-word translation, and a natural usage example. No more getting confused by phrases like "let bygones be bygones."
6. Contextual Vocabulary Capture
Building your personal dictionary has never been easier.
Right-Click to Save: Highlight any word on any webpage, right-click, and select "Add to Lexora."
Smart Context Grabbing: Lexora doesn't just save the word; it automatically extracts the surrounding sentence and the source URL, saving them to your Lexora profile. When you review the flashcard later, you will remember exactly where and how you found the word.
