Everything Lexuri can do
Four interlocking systems — each one designed around how the brain actually acquires language.
Learning Feed
A curated social feed of TED talks, YouTube videos, and music — organized by CEFR difficulty level. Browse what the community is studying, save items to your queue, and open any content directly in the study tools.
- → Filtered by level: A2, B1, B2, C1
- → Videos and music in one unified feed
- → Save to personal study queue
- → Jump straight into YouTube Studio or Music Lab
YouTube Transcripts
Paste any YouTube URL. Lexuri fetches the transcript and syncs it with the video frame by frame. The active word highlights in real time as you listen, so your eyes and ears train together.
- → Auto-sync word highlighting
- → Adjustable caption delay calibration
- → Click any word to instantly collect it
- → Works with auto-generated and manual captions
Language Chunk Detection
Built with neuro-informed learning principles, Lexuri's AI detects the units your brain actually stores — not isolated words, but complete expressions. Every chunk comes with a contextual translation into your language and a note on why it matters for fluency.
- → Phrasal verbs ("give up", "freak out")
- → Idiomatic expressions ("at the end of the day")
- → Collocations ("make a decision", "break the ice")
- → Formulaic sequences and conversational patterns
AI Flashcards
Every word or chunk you collect becomes a rich flashcard — with a translation, plain-English explanation, and a natural example sentence. No manual typing. The AI handles the card content automatically.
- → Contextual + literal translations into your language
- → English explanation in simple language
- → Example sentence from the original content
- → Batch generation or one at a time
Spaced Repetition Review
The SM-2 algorithm tracks exactly when you're about to forget each card and shows it to you right at that moment. Rate your recall from 0 to 5. The system adapts its schedule per card — you stop wasting time on what you already know.
- → SM-2 spaced repetition algorithm
- → Per-card ease factor and interval tracking
- → Daily review queue shows only due cards
- → Tracks words from both YouTube and music sources
