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
