Thanks to the sophisticated algorithm within Dejavu English, every word or phrase you add to your
notebook is carefully monitored. With this algorithm, it reminds you at optimal intervals based on each
word's learning status. This way, it helps you transfer words from your short-term memory to your
permanent long-term memory.
Vocabulary acquisition in a language is reinforced through repetition and practice. Aware
of this fact, Dejavu English supports the process of repetition and practice with interactive, multi-dimensional tools.
SRS — Spaced Repetition System
For vocabulary learning, this program uses a more advanced, specially modified version of the SRS — Spaced Repetition System method described in the Fluent Forever book, tailored for Dejavu English. SRS is a scientific method that ensures learned information is embedded into long-term memory.
How SRS works:
The human brain loses information according to the forgetting curve: we forget newly learned things quickly.
SRS reverses this curve by making you review information just before you forget it.
Each review interval grows progressively longer:
1st review → minutes/hours later
2nd review → 1 day later
3rd review → 3–4 days later
Later reviews → 1 week, 1 month, 3 months…
SRS in Dejavu English:
Based on the SRS value of words in your notebook, Dejavu English selects 5 or 10 words as your daily mandatory review.
Important: If you don't complete a review session, those same words carry over to the next day. They stay as tasks until practice is finished.
Practice Methods
Dejavu English offers multiple practice methods to reinforce words from different angles. Each method targets a different dimension of learning — used together, they maximize retention.

Instant in-browser or in-app voice recording (up to 30s)

Phrase Practice Methods:
Recall and Speak: The sentence or expression is first shown in your native language. After thinking of how to say it in English, click "Show" to reveal the English expression and hear its native pronunciation — then repeat it aloud using the Shadowing technique or by recording your own voice.
Listen and Write: Listen to the expression spoken aloud and type what you hear. Combines listening and writing to lock phrases into long-term memory.
Daily Task System:
Each day, Dejavu English automatically selects the words and phrases with the lowest SRS score — those most urgently needing review — and presents them as your daily tasks. Completing these tasks keeps your vocabulary fresh, active, and moving steadily into long-term memory.
From your dashboard you can track due and overdue reviews as well as the memory distribution of your words and phrases (flash memory, short-term memory, and long-term memory) at a glance.
