Deja 从一个问题开始: 语言,为什么总是被学成抽象的单词? 在真实世界中,语言来自视频、播客、阅读和声音。 Deja 将这些语境中的表达自动提取、组织,逐渐形成一个属于自己的语料系统。 复习不再是孤立的记忆,而是回到语言第一次出现的那个语境。 阅读、听力、学习不再分离,所有输入汇聚成一条连续的语言路径。 Deja 不属于某一种格式或平台,它试图构建的,是一个会随着使用不断生长的语言系统。 Deja starts with a simple idea: Language is not learned from isolated words, but from real usage. Import videos, podcasts, books, or any text. Deja automatically captures phrases in context and turns scattered exposure into a growing personal corpus. Review is not repetition. It is a return to the moment where the language first made sense. Reading, listening, and studying are no longer separated. Everything flows into one continuous system, one evolving memory. Deja is not about formats or platforms. It is about building a language system that grows with you.
