What Problem Does Dejavu English Promise to Solve?
The core problem most people face when learning English is that they can't save or consistently organize the words and phrases they hear in daily life or come across while reading.
Gathering these words into one pool and reviewing them at regular intervals helps them settle naturally into your speech and become permanently fixed in your memory.
We've brought together every step you need while learning English into a single integrated platform.

Common Questions
Can I start for free without a credit card?
Yes. Every new account unlocks a 14-day Pro trial with no credit card required, and you can continue on the free plan afterward.
How does the Dejavu Effect™ work?
Words saved in your notebooks are automatically highlighted when they appear in new articles you read, showing your notes and context on hover.
Why should I use a more modern alternative like Dejavu English instead of Anki?
With Anki, you have to build flashcards manually one by one and review words detached from real texts. With Dejavu English, you save words in one click while reading; the integrated dictionary automatically brings the word's contextual meaning, pronunciation, and examples.
For every word, you can get AI-powered memory cue (mnemonic) suggestions or create your own and attach them directly to the word.
When you read new texts with the Dejavu reader, your saved words reappear color-coded by your mastery level and are reinforced through modern interactive practices.
Plus, across the Dejavu English mobile app and browser extension ecosystem, every word or phrase you save is instantly synced to your central digital notebook.
Which English levels is Dejavu suitable for?
It is suitable for learners from A1 up to C1, including students preparing for IELTS, TOEFL, and SAT.
