DejaVocab - An English learning tool that captures every word and phrase.

It's not just about learning English through videos; it's about turning every word, phrase, and sentence in the video into learning material.

Watch a video once, and you'll build a lifetime of vocabulary.

Core Concept

Traditional Method: Memorizing Words in Books - Out of Context - Impossible to Remember DejaVocab: Real Videos - Full Context - Permanent Memory

For each word, we know: - Which video it appears in - In what sentence - The context - The speaker's tone

Every phrase is tracked: - AI automatically identifies authentic phrases - Records all occurrences - Compares different usages

Every sentence is saved: - Save key phrases with one click - Return to the original video at any time - Accurately tracked down to the second

This is true "immersive learning"

[Words Are No Longer Isolated]

Click any word in the video subtitles: - See sentences where this word appears in all the videos you've watched - Compare usages in different contexts - Build a "memory network" of the word

For example, the word "run": - In fitness videos, it's "跑" - In business videos, it's "操作" - In technology videos, it's "跑" DejaVocab helps you memorize all these usages!

[AI Phrase Discovery] You don't search for phrases; AI finds them for you: - Automatically identifies common collocations in videos - "give up," "look forward to," "break down" - Categorizes phrases by video and sorts them by frequency of use - Each phrase has a real-world usage scenario

[Instant Sentence Collection] Stumble upon a good sentence? One-click saving: - Automatically records video, time, and context - Generates AI translations - Search function: Enter Chinese characters to find English sentences - Click on a sentence to jump directly to that second in the video

Exclusive Features

[Language Chunk Tracking System] Your own English database: - Watch 50 videos = accumulate 5,000+ word contexts - Each word has a "personal profile" - Look up any word: Instantly see where you've encountered it

[Scrolling Translation] Understand as you watch, immersive experience: - Automatic subtitle translation, displayed in real time - Option to show/hide translations - AI grammatical analysis: Understands sentence structure

[Smart Player] Optimized player for language learning: - Sentence loop: Listen to sentences you don't understand repeatedly - Listening mode: Hide subtitles to test comprehension - 0.5x-2.0x speed adjustment: Adapts to your pace - Picture-in-picture: Take notes while watching

[Deja Smart Definition] Not a dictionary, but an AI teacher: - Explains complex words in simple terms - Personalized explanations based on video context - Examples are from videos you've watched
