## What is EchoEcho  AI?

Still forgetting words right after memorizing them?
It’s time for a smarter way to learn vocabulary.

This app combines the Ebbinghaus Forgetting Curve with AI-powered conversational learning, so your reviews are no longer mechanical, but dynamically adjusted based on your real level of mastery.

Core Experience

Replace multiple choice with real conversation
The AI asks like a real teacher:
Do you really know this word?
Say its meaning in your own words.
Build long-term memory through active recall and real expression.

AI understands your mastery
Not just right or wrong —
your answers are analyzed to measure how well you truly understand.

Personalized review rhythm
Your next review time is calculated automatically
so every session happens right before you’re about to forget.

Learns you as you learn
Every response you give
makes your study plan more precise.

What you’ll gain
• No more ineffective repetition
• Real long-term retention
• Memorizing words like practicing with a real tutor
• A fully personalized learning pace

Who it’s for
• Learners who keep forgetting vocabulary
• Anyone who wants higher study efficiency
• The new generation of AI-powered learners

Memory shouldn’t rely on willpower — it should rely on science.
Let AI ask the right question at the perfect time.
