Deja Mate is a flashcard application designed specifically for memorizing long passages, sentences, explanations, procedures, speeches, definitions, and other text-based content.
Unlike traditional flashcard apps that focus mainly on short words or simple question-and-answer pairs, Deja Mate allows users to enter longer text and convert selected parts into fill-in-the-blank questions.
Users can write or paste any text they want to remember, mark important sections as answers, and study them repeatedly through structured quiz modes.
Deja Mate is intended for language learning, exam preparation, technical study, speech practice, professional training, and personal learning.
The app is designed to support users in organizing difficult material, reviewing it efficiently, and gradually improving recall.
Deja Mate is built for users who need to memorize more than individual words.
Users can enter full sentences, paragraphs, explanations, procedures, or other long-form content and turn selected portions into fill-in-the-blank questions.
Each marked section is treated as an individual learning item.
Each answer has its own memory level.
Users can evaluate their recall during each quiz, and the app records progress for each item separately.
This helps users identify:
Content they remember well
Content that still requires practice
Sections that are improving over time
Areas that should be reviewed more frequently
Loop Mode allows users to focus on a limited set of questions and review them repeatedly.
This mode is useful when users want to concentrate on a specific passage, difficult section, or smaller group of learning items.
Holistic Mode selects questions from across the user’s study content while considering memory levels.
Questions that require more attention may appear more frequently, helping users focus on weaker areas while continuing to review previously learned material.
Deja Mate displays learning progress through graphs and memory-level information.
Users can review how their performance changes over time and understand their overall learning status visually.
Users may add images to their flashcards.
Images can be selected from the device’s photo library or captured using the device camera.
This feature is optional and is intended only to help users create more useful and memorable study content.
Users can organize study content into separate files.
This makes it easier to manage different subjects, topics, exams, languages, projects, or learning goals.
Study content, memory levels, settings, images, and quiz records are stored locally on the user’s device.
Deja Mate does not require an account or online registration.

Device passcodes
Biometric authentication
Encrypted backups
Secure device settings
No digital storage method can be guaranteed to be completely secure.
