Koki Flashcards – Learn Vocabulary Effectively with Smart Spaced Repetition
Koki Flashcards is a smart multilingual flashcard app that helps you learn vocabulary faster, remember it longer, and study more effectively. Using a Spaced Repetition System (SRS), Koki shows you the right flashcards at the right time, allowing you to focus on the words you are most likely to forget.
Whether you are learning English, Japanese, Korean, Chinese, Spanish, or another language, Koki Flashcards helps you build long-term memory with ready-to-use vocabulary decks, custom flashcards, images, audio, examples, and personalized review schedules.
Key Features
• Flashcards with Spaced Repetition
Koki Flashcards uses SRS to help you remember vocabulary more efficiently. Difficult words appear more frequently, while familiar words appear less often, making every review session more focused and effective.
• Ready-to-use vocabulary flashcard decks
Start learning immediately with organized flashcard decks for a variety of languages and learning goals:
* English communication
* TOEIC vocabulary
* IELTS vocabulary
* Japanese N5–N2

Each deck is arranged from basic to advanced levels, helping you learn step by step and build a strong vocabulary foundation.
• Learn faster with images, audio, and examples
Koki Flashcards makes every flashcard easier to understand and remember by combining:
* Illustrative images
* Clear word meanings
* High-quality pronunciation audio
* Practical example sentences
* Helpful usage context
By learning with text, sound, visuals, and examples, you can improve your memory and retain vocabulary for longer.
• Build custom flashcards in seconds
Add words, meanings, images, audio, examples, and pronunciation to create your own learning system. Koki can also generate pronunciation audio for your vocabulary, making it easier to create complete and useful flashcards for daily study.
• Personalized review schedules
Koki Flashcards automatically adapts to your pace, progress, and memory performance. The app helps you spend more time on difficult vocabulary and less time on words you already know, providing a smarter and more efficient way to study.

Study your flashcards anytime, even without an internet connection. Your learning data can be synchronized across devices, allowing you to continue reviewing vocabulary wherever you are.
