DejaVocab
Education
Free · In‑App Purchases · Designed for iPad
Deja is built around a single question:
How can language learning stay rooted in real usage, instead of drifting into abstraction?
It starts with natural input such as videos, podcasts, and reading materials. Through automatic analysis and organization, fleeting moments of exposure are transformed into a growing personal corpus. Review is not isolated memorization, but a return to the original context where the language first appeared.
The EPUB reader is not an additional learning path. It brings reading into the same system, allowing spoken and written language to share one context and one memory trajectory.
Deja is not concerned with formats or platforms.
What matters is whether scattered input can converge into a living, continuously evolving language system.
