Detailed Description

We have created the most effective tool for memorizing words while learning foreign languages.


This project is a favorite of schoolchildren, students, and those who need to quickly increase their vocabulary.


The algorithm is based on neurobiology and the science of memory. It translates new information from short-term to long-term memory through an adaptive interval repetition algorithm.


This product will be useful for schools, universities and language courses.


By practicing 20 minutes a day, the user will memorize an average of 30 new words. And the system of long-term practice will not allow him to forget them.


Features of the app:

- practicing memorization of words and phrases

- 4 learning modes: basic (vocabulary pumping), long-term practice with intervals from 1 day to 3 months, backward practice (e.g. En->De for De->En)

- Adaptive algorithm that adjusts the interval depending on the quality of the answer, number of previous errors, etc.

- pronunciation voicing (Google)

- generation of audio training based on recently learned words

- AI generation of text for reading practice based on recently learned words

- using ready-made word sets

- adding your own words for learning (including mass addition) with automatic translation and editing.

- creating your own word sets

- dictionary management

- ability to share your own word sets

- user rating (competition)

- motivation system (make at least 50 cards a day to collect a series of days and color them in the calendar)

- adding friends and tracking their statistics (+ "Motivate a friend" button)

- reminders

- personalized workout statistics

- monetization system (freemium model: free cards for classes every n hours or purchase full access (different rates)

- settings: notifications, name management, account deletion



A user-friendly control system is available for the app, where you can easily add any language pairs.


Content and data management system:

- сreating levels for the classic 5,000-word set

- сreating an infinite number of themed sets

- translation management (word + translation + context sentence)

- word import

- search for duplicate words and translations

- generating contextual sentences with AI

- adding new languages

- user management (adding cards, premium, etc.)

- user activity statistics (online, activity, DAU, WAU, MAU)

- in-depth sales funnel statistics

- information page builder

- payment management

- notification system

- creating administrators and content managers

No special skills are required to manage content.


Users spend an average of 10 minutes a day in the app. The high DAU rate is achieved thanks to our system of motivation to practice every day.


All developed by us from scratch and tested on 10,000 users. More than 150 improvements have been made.


Now this web application functions as one of the first Telegram applications.


The API structure of the project makes it easy to integrate it into websites and create IOS and android applications. All you need to do is connect the interface and set up a user identification system.


We are ready to deploy a test environment for you to fully test the capabilities of the platform for your needs.


The project is complete, no additional work required.

We really love this project and use it ourselves, that's why it's so cool.


If you see another form of cooperation besides purchasing - please write to us.
