I built a tool that turns my online French lessons into recaps, flashcards and practice tests

I've been learning French for 6 months with an online tutor. Every lesson would end and after 2 weeks I'd forget where we left off and what we learnt, and I couldn't see my progress. So I built Lesson Journal. It records my lessons (Chrome extension, on a laptop/PC), reads my previous lessons and combines them, plus a bunch of metrics that show my growth. It also builds practice tests from our lessons following a real exam structure, and flashcards based on our lessons, so it only shows me

AI 分析

痛点:在线语言学习者课后容易遗忘课程内容,无法系统回顾学习进度并针对性复习。

目标用户:有在线一对一/小班语言课程的学习者,尤其是希望跟踪进度、自动生成复习材料的人。

证据:I've been learning French for 6 months with an online tutor. Every lesson would end and after 2 weeks I'd forget where we left off and what we learnt, and I couldn't see my progress. ... Would you pay for something like this? What would stop you?

变现:Freemium:免费保存少量课程,付费订阅解锁无限录制、AI转写总结、生成练习/抽认卡和进度分析;也可面向语言教师/机构提供批量套餐。

MVP:做一个 Chrome 扩展,录制浏览器内的在线课程音频,调用 Whisper 转写 + LLM 生成课程摘要、生词表和考试式练习题,并支持导出 Anki/Quizlet;先做英语/法语单语言验证。

竞品:Anki、Quizlet、LingQ、Otter.ai、Notta、ChatGPT/Notion 模板

摘要:发帖人学法语6个月,因课后遗忘内容和进度,做了 Lesson Journal:Chrome扩展录制在线课程,生成回顾、抽认卡和考试式练习,支持任意语言。帖中只问“Would you pay for something like this?”,没有用户付费反馈或收入数据,需求真实性尚未验证,且面临Anki、Quizlet、AI会议笔记等竞品。独立开发者可较快做出MVP,但需验证隐私合规和付费转化。
