About this app

【What is Cobo Memo?】
In this age where AI provides answers, Cobo Memo transforms "thinking you understand" into "memories you can use at work."
Cobo Memo is a learning app that maximizes memory retention through AI-powered automatic generation of vocabulary lists and interval repetition (SRS) based on the forgetting curve.
It reduces the time spent creating flashcards from an average of 4 hours to 30 minutes, allowing you to focus on learning itself.

■ Recommended for:
・Those who quickly forget what they've learned
・Those who repeatedly look up the same things
・Those who can't recall information instantly when needed
・Those who don't know when to review
・Those who want to transform "thinking you understand" into memories they can use at work
・Those who want to streamline their learning of AWS, information processing, TOEIC, LPIC, English proficiency tests, etc.
・Instructors and training managers who want to distribute decks to students in corporate training, schools, and learning groups

■ Main Features
【1】Streamlined vocabulary list and flashcard creation with AI
Automatically generates questions, correct answers, supplementary explanations, and multiple-choice options from text, images, and videos. Supports a workflow that allows you to directly paste ChatGPT answers to create flashcards.

[2] Review Notifications Before You Forget (Spaced Repetition/SRS)
Based on Ebbinghaus's forgetting curve, automatic notifications are sent at the optimal time. The interval automatically widens from 1 day → 3 days → 7 days → 14 days → 30 days, achieving maximum retention with minimum effort.

Cards can be created and managed not only from the smartphone app but also from a PC browser. You can create cards on the spot at your desk while working.

Limited-access decks, student progress tracking, and invitation links enable use in corporate training, qualification schools, and learning groups. One instructor can distribute to all students.
