I'm the maker of Mermaid. I kept wanting to get things done on my Mac while away from it, so I built an assistant you message from your iPhone. It operates your real apps and files, and asks for your approval before anything with consequences (sending, deleting, buying). It's early and I'd love honest feedback: what would you want it to do?

痛点：离开 Mac 时没法处理只存在电脑上的实际任务（发消息、整理文件、删除/购买等），手机端缺少一个能安全操控真实 App 和文件的代理。
目标用户：Mac 重度用户、独立开发者、经常外出但需要远程处理文件与消息的知识工作者。

变现：订阅制（约 $5–15/月）分档：免费额度 + 按任务量计费；Pro 解锁多设备、自定义自动化工作流、模型自选；TestFlight 结束后直接转付费墙。
MVP：2 周内只做 3 个动作：读取指定文件夹并摘要、生成邮件/消息草稿待确认发送、运行用户预设脚本。Mac 端用轻量常驻 agent（AppleScript/快捷指令+SSH 隧道），iOS 端用极简聊天界面，所有写操作强制确认弹窗，用 TestFlight 拉 20 个种子用户验证哪类任务最常被调用。
竞品：Apple 屏幕共享 / Continuity、Jump Desktop、Screens、Shortcuts + SSH、Claude / OpenAI computer use 类代理、OpenClaw 等开源 Mac agent
摘要：独立开发者在 r/SideProject 发布 Mermaid：用 iPhone 发消息即可让助手在 Mac 上操作真实 App 与文件，涉及发送、删除、购买等高后果动作前会请求确认，目前处于 TestFlight 早期并公开征求反馈。帖中未提及定价、收入或任何第三方付费意愿，需求仅由作者自身『离开 Mac 也想办事』的痛点支撑。远程控制与 AI 电脑代理赛道竞品已不少，差异化要靠安全确认机制与移动端体验。
