无论是学习西班牙语、法语、日语，还是语言学习本身的问题，都能获得一份完全基于已发表研究的报告。不猜测，不靠民间说法。
Sample report, shortened
Do subtitles help you learn a language?
Captioned video improves vocabulary recognition and listening comprehension once you’re past beginner levelSource 1, but true beginners get more out of subtitles in their own language firstSource 2. It depends where you’re starting from.

没有来源，就没有结论——若研究无法支撑某个说法，报告会如实说明，而不是随意猜测。
当某种语言或问题的研究有限时，报告会直接告诉你，而不是装出比证据本身更笃定的样子。
关于语言学习的优质研究确实存在，只是被锁在付费学术期刊里，写给研究者看的。我们替你读完，并转化成你能直接用上的建议。
01
用日常语言输入你的语言学习问题——无需特殊语法，无需关键词搜索技巧。
02
系统会检索、排序并完整阅读真实的学术资料——而非依赖模型训练数据中的概括。
03
一份清晰的报告，每条结论都能追溯到具体出处。
Good research on how people actually learn languages exists. It's just locked in journals and written for other researchers.
Most learners have two places to turn: the hard-won experience of people who've made the journey, or whatever the algorithm has decided is popular.
Both have real value. Neither is the same as evidence.
We read the journals, filter for what holds up, and write it in plain language — so what guides your learning is research rather than guesswork.
