I built a free desktop app that detects and covers porn on your screen in real time, fully offline

Hi guys, A friend and I started this at a hackathon and kept working on it afterwards. It's called LAVOCADO, a desktop app for people who have decided they want to quit porn and want something that actually helps in the moment. Most porn blockers only check URLs or app names, which is easy to get around (social media, image search, random links). LAVOCADO looks at what is actually on the screen instead: . It captures the screen locally and runs a nudity detection model on

AI 分析

痛点:传统色情屏蔽工具只检查网址或应用名,很容易被社交媒体、图片搜索、随机链接绕过;用户真正需要的是基于屏幕实际内容的实时识别与阻断,并且要隐私安全、数据不上传。

目标用户:想戒除色情的成年人(戒色、NoFap 人群),以及需要监护人控制、自我约束工具的家长和重度拖延用户

证据:Most porn blockers only check URLs or app names, which is easy to get around (social media, image search, random links). LAVOCADO looks at what is actually on the screen instead... Privacy was the main design constraint... Screenshots are processed in memory and never uploaded or saved. It's free for personal use (source-available under BSL 1.1)

变现:免费开源版作为获客入口,付费订阅提供云端同步的戒断数据看板、问责伙伴(accountability partner)通知、绕过尝试提醒、多设备管理,以及家长控制版;也可做一次性买断的签名安装包与技术支持。

MVP:用现成开源 NSFW 检测模型(如 NSFWJS / open-nsfw)配合 Electron 或 Tauri 做跨平台桌面端:定时截屏、在本地推理、命中后覆盖当前显示器并弹出 30 秒呼吸和打字冷静倒计时;全程本地处理,不保存截图,先只支持 Windows,用 GitHub 发布未签名版本收集反馈。

竞品:Covenant Eyes、Truple、Pluckeye、Cold Turkey Blocker、LAVOCADO(原帖产品)

摘要:作者在 Reddit 发布了免费、源码可得的桌面应用 LAVOCADO,它用本地运行的裸露检测模型实时识别屏幕内容并遮住对应显示器,之后弹出打字冥想或可选的 AI 对话帮助用户熬过冲动。隐私设计是核心卖点:截图仅在内存中处理、不上传不保存、不记录 URL。项目采用 BSL 1.1,个人免费,目前仅支持 Windows 10/11 和 Apple Silicon Mac,安装包尚未签名。帖子本身没有付费或收入证据,但戒色与家长控制领域已有 Covenant Eyes 等成熟付费产品,可在此基础上做订阅制增值方向。
