2026年8月25日，macOS 菜单栏文本记录应用 Ambient Context 发布了早期未签名版本 1。该应用通过 macOS 辅助功能 API 每几秒读取当前焦点窗口的文本内容，并将其以纯 Markdown 格式按日追加到用户指定的本地文件夹中，每天生成一个文件，供大语言模型代理读取以回顾工作内容 1。该应用不依赖截图或录像，且仅读取当前焦点窗口，不会读取后台窗口、其他显示器或最小化窗口，在设备锁屏时也会停止工作 1。
在隐私与安全方面，Ambient Context 不联网、无账户、无服务器、无遥测且无内置模型 1。应用会自动跳过密码管理器和隐私浏览窗口，并在写入前清除凭据、API 密钥及银行卡号等敏感信息 1。该应用要求系统为 macOS 14 及以上版本并搭载 Apple Silicon 芯片 1。由于目前处于早期未签名阶段，用户需要使用 Node、Rust 和 Xcode 命令行工具自行编译构建，项目代码已托管至 GitHub（https://github.com/dragthelake/ambient-context） 1。
A new macOS menu bar application named Ambient Context has been introduced, offering a text-based approach to screen memory without relying on screenshots 1. The tool utilizes the macOS accessibility tree to read the text content of the currently focused window every few seconds 1. Instead of capturing images, it outputs the extracted text into pure Markdown files, creating one file per day and appending it to a user-specified local folder 1. This design allows large language model agents to read the logs and review past work activities 1.
Privacy is a central focus of the application, which operates entirely offline without taking screenshots, recording video, connecting to the internet, or utilizing any accounts, servers, telemetry, or built-in models 1. To protect sensitive data, Ambient Context automatically skips password managers and private browsing windows, and it scrubs credentials, API keys, and card numbers before writing to the files 1. Furthermore, it only reads the active focused window, ignoring background windows, other displays, or minimized windows, and it pauses operation when the screen is locked 1.
The application requires macOS 14 or later and an Apple Silicon processor to run 1. Currently in an early, unsigned stage, the software requires users to build it themselves using Node, Rust, and Xcode Command Line Tools 1. The source code is available on GitHub at https://github.com/dragthelake/ambient-context 1. The release event occurred on August 25, 2026 1.
