I built a Japanese learning app to practice conversations for my upcoming trip in Japan. Should I open it up?

I am currently relearning Japanese to have conversations with locals for my upcoming trip. It was really hard for me to practise real life scenarios and also to track what vocabulary or grammar I know well or struggling with. I'm used to flashcards, duolingo, textbooks but I couldn't find any other apps for like intermediate level. So I built an app solely because I needed it for my study. Here's how it works: I pick a real-life scene (ordering at an izakaya, hotel c

AI 分析

痛点:中级日语学习者缺少能模拟真实生活场景(点单、酒店入住、闲聊)的对话练习工具,且难以追踪自己已掌握/薄弱的具体词汇和语法点。

目标用户:已有基础、准备赴日旅行或备考JLPT N3-N2的中级日语学习者(自学者为主)。

证据:I couldn't find any other apps for like intermediate level. / Right now its just built for myself but if you think could this be genuinely useful or not, plz leave a comment so I can have better understanding of the demand.

变现:免费试用3-5个场景,之后订阅制(月付/年付)解锁无限对话与JLPT语法追踪;或按对话次数卖credits;面向日语学校/留学中介做B2B授权。

MVP:2周内用现成LLM+STT/TTS API搭一个Web应用:预置15-20个赴日旅行场景(居酒屋点单、酒店check-in、租自行车等),每轮对话后自动标注错误、抽取新出现的语法并对照JLPT N3-N2约430条语法表打标签,生成Anki可导入的复习卡片。核心差异化放在「练完自动生成个人语法弱点复习队列」。

竞品:Duolingo、TalkPal、Langua、Pingo AI、Speak、ChatGPT语音模式、Bunpro、Renshuu

摘要:作者为赴日旅行自学日语,因找不到中级水平的口语练习工具而自建App:AI扮演居酒屋点单、酒店入住、酒吧闲聊等场景对话,实时纠正发音表达,并对照约430条JLPT语法点追踪新学词汇语法以便复习。作者目前只为自己使用,发帖询问是否有人觉得有用,帖子中没有任何付费意愿或收入数据,需求验证尚不充分。
