Atticus：面向 macOS 的按住说话语音助手
九年级学生 Saarth 在 Hacker News 发布开源 macOS 助手 Atticus：按住 Control-Option-Space 说话或输入任务即可执行。简单任务（打开应用、播放 Spotify 歌单、网页查询）在本地处理，通常 1 秒内完成，例如打开应用约 0.08 秒；较复杂的任务则通过 claude -p 交给 Claude，无需 API key，可直接使用已有的 Claude Pro 或 Max 订阅，作者称单次任务成本通常不到一美分。Atticus 会记住首次完成任务的步骤并在之后直接回放（例如新建会议的流程从约 30 秒降到 5–8 秒），并在使用中积累用户信息以个性化回答；删除、发送、购买或写入文件前会先弹出确认。目前运行需要 macOS 26 或更高版本以支持本地语音转写，作者称仍在开发会议副驾驶，并表示软件免费、开源且存在不少粗糙之处。
它展示了一种低成本助手思路：把本地快捷操作回放与已有的 Claude 订阅结合，绕过 API 计费。
Hi HN! I'm Saarth. I'm in 9th grade, and I built Atticus.
Atticus is a fast and cheap Mac assistant that can do tasks for you. You hold down Control-Option-Space, speak or type your task, be it complex or a simple browser search, and Atticus will get on it.
The interesting part is that simple tasks, like opening apps, playing a Spotify playlist, or web queries, don't touch AI, and instead are processed locally and typically finish in under a second. For example, prompting Atticus to open apps takes around 0.08 seconds, sometimes even finishing before you finish your sentence, sort of like Jev.
Any tasks that are more complicated will be sent to Claude via claude -p, meaning you never need an API key and Atticus will run on your existing Claude Pro or Max plan. By using this approach, costs are also cut down immensely, with, on average, tasks costing a fraction of a cent.
To achieve Atticus' speed, it remembers shortcuts from each task it completes. When it does a task right for the first time, it saves its steps and replays them the next time without AI. For example, a workflow of creating a new meeting took about 30 seconds the first time around. Atticus then logs the exact steps to memory and takes 5-8 seconds on the next pass. To add to this, Atticus also learns about you as you use it more and from what's on your computer, including your name, your apps, and things you want it to remember, personalizing its answers to you.
