痛点：主流闪卡应用强制订阅、强制注册、数据必须上云，用户想要一次买断、无账号、可离线的本地化学习工具

目标用户：备考学生、语言学习者以及注重隐私的 iPhone/iPad 用户

证据：Tired of flashcard apps that want a subscription, an account, and a round trip to someone's server every time you make a card? … One-time $6.99 CAD: spaced repetition scheduling, decks from photos/audio/video… No subscription, ever.

变现：一次性买断 $6.99（含 Family Sharing），或免费版 + 一次性内购解锁间隔重复、AI 辅导、多媒体制卡等高级功能

MVP：2 周内做 iOS/iPadOS 本地闪卡应用：SwiftData 本地存储 + SM-2 间隔重复算法 + Anki(.apkg)/CSV 导入导出 + 完全离线无账号，AI 辅导与拍照制卡作为后续版本

竞品：Anki、Quizlet、RemNote、Brainscape、Mochi

摘要：开发者发布了一款完全本地运行、无账号无服务器的闪卡 App Cerebri，主打隐私与买断制，一次性收费 6.99 加元。功能覆盖拍照/录音/PDF 制卡、SM-2 间隔重复、本地 AI 辅导和 Anki/Quizlet 导入。帖子验证了「反订阅 + 离线本地化」这一细分诉求，但闪卡赛道竞品密集，且原帖未给出任何真实收入或用户付费评论。
