痛点：Reddit API 变更后，长期用户缺少低成本、可选择性保留高价值评论的一次性批量清理/覆盖工具。
目标用户：注重隐私、拥有多年 Reddit 账号和数千条评论、只想一次性清理历史的用户
证据：Reddit API changes killed most of the tools available, the online reliable one left was Redact, however I didn't like it because: - it was expensive (it costs $100 billed annually). I planned to use it only one time so it wouldn't work for me. - I didn't want to remove valuable contributions made along the years. I could uncheck specific comments, but imagine going through a list of thousands of comments. It'd be boring af.
变现：一次性买断许可证（如 $9–$19），可选高级功能订阅；本地桌面版降低服务器成本
MVP：2周内做本地桌面 MVP：导入 Reddit data export，扫描评论，Tinder 式滑动保留/覆盖，批量用随机词覆盖，导出结果，不发送账号数据，无推广后缀。
竞品：Redact
摘要：作者因 Reddit API 变更导致多数清理工具失效，找到的 Redact 年费 $100 且不适合一次性使用，手动筛选数千条评论也很痛苦。于是做了本地桌面工具，支持导入数据、滑动选择、将评论覆盖为乱码以规避第三方存档，并保留 karma。这显示 Reddit 历史清理存在明确但较窄的付费需求，竞品价格高且体验有改进空间。
