微软正在秘密测试一款面向Windows 11的新型人工智能应用，其内部代号为“Project Pantheon”。与此前曾引发广泛讨论的Recall功能不同，这款新工具不会自动记录用户屏幕上的所有活动，而是仅保存用户主动选择的内容，因此被外界视为一种更加注重隐私的新型“记忆系统”。
据测试信息显示，Project Pantheon目前以“Context Vault”的名称出现，同时还涉及“Context IO”和“Projects”等多个内部命名。尽管微软尚未正式公布该项目，但相关应用已经通过未公开的微软商店页面进行测试，并被部分用户发现和体验。
从功能角度来看，Context Vault更像是一个个人数字记忆库。用户可以主动保存网页、文件、截图、复制的文本内容以及音频和视频资料，并将这些内容整理到不同的收藏集之中。随后，用户能够通过AI对这些资料进行搜索、提问和总结，从而快速找回此前保存的信息。
应用主界面包含收藏集、资料库、聊天、时间线、令牌使用情况以及外部连接等多个板块。系统既支持用户手动创建分类，也能够利用人工智能自动生成内容集合。不过测试版本仍处于早期阶段，部分自动生成的分类名称甚至出现了“None”和“null”等明显未完善的情况。
与传统笔记应用不同，Project Pantheon被深度整合进Windows 11系统。用户无需专门打开应用即可保存内容。通过浏览器扩展、文件资源管理器、Windows共享菜单、剪贴板、屏幕截图工具以及部分兼容应用，内容都可以直接存入记忆库之中。
在文件资源管理器的共享菜单中，Context Vault已经能够像WhatsApp、Outlook等应用一样作为分享目标出现。用户只需数次点击便可将图片、文档等资料保存到自己的AI记忆库。
微软还为该项目接入了Windows 11的“Click to Do”功能。在系统设置中，应用注册了“保存图片到Projects”和“保存选中文本到Projects”等操作选项。这些功能仍然沿用了项目早期的“Projects”名称，进一步表明该应用目前尚处于开发测试阶段。
另一个值得关注的特点是开放的AI生态能力。Project Pantheon不仅能够管理本地保存的信息，还可以通过MCP服务器向Claude和Cursor等第三方AI工具共享相关上下文内容，让不同AI服务访问用户授权提供的资料并协同工作。
报道指出，如果用最简单的话来形容Project Pantheon，它更像是一个“第二大脑”。与Recall通过持续截取屏幕快照自动建立完整历史记录不同，Pantheon强调由用户主动决定保存哪些信息，再利用人工智能帮助整理、检索和理解这些内容。
目前微软尚未正式宣布Project Pantheon的发布时间、商业计划或最终产品名称。不过从已曝光的功能来看，公司似乎正在探索一种比Recall更具隐私控制能力的AI信息管理方案，希望帮助用户建立个人知识库，同时避免持续屏幕记录所带来的争议。

Microsoft is secretly testing a new artificial intelligence application for Windows 11, internally coded “Project Pantheon”. Unlike the Recall function, which had previously been the subject of extensive discussion, the new tool would not automatically record all the activities on the user screen, but would only preserve the content of the user's choice and would therefore be seen by the outside world as a new “memory system” that is more privacy-oriented.
According to the test information, Project Pantheon currently appears under the name “ContextVault” and also involves multiple internal names such as “Context IO” and “Projects”. Although Microsoft has not yet officially published the project, the applications have been tested through an undisclosed Microsoft shop page and have been detected and experienced by some users.
From a functional point of view, Context Vault is more like a personal digital memory bank. Users can actively save web pages, files, screenshots, copying text contents and audio and video materials and organize them into different collections. Users are then able to search, question and summarize this information through AI in order to quickly recover the previously held information.
The application main interface consists of various segments such as collections, databases, chats, time lines, token usage and external connections. The system supports both the creation of classifications manually by users and the automatic generation of content pools using artificial intelligence. However, the test version is still in its early stages, and there is even an apparent imperfection of some of the self-generated classification names, such as “None” and “null”.
Unlike traditional notebook applications, Project Pantheon was Depthly integrated into Windows 11. Users do not need to open applications to save content. Through browser extensions, file resource managers, Windows shared menus, clipboards, screenshot tools and partially compatible applications, content can be placed directly in memory libraries.
In the shared menu of the File Resource Manager, Context Vault can already appear as a shared goal like the WhatsApp, Outlook etc. Users can save pictures, documents, etc. to their own AI memory libraries by clicking several times.
Microsoft also accessed the Windows 11 “Click to Do” feature for the project. In the system settings, operational options such as Save Picture to Projects and Save Selected Text to Projects are registered. These functions continue to follow the project's early name “Projects”, further indicating that the application is currently in the development testing phase.
Another feature of concern is the open AI ecological capacity. Project Pantheon not only manages locally stored information, but also shares context content with third-party AI tools such as Claude and Cursor through the MCP server, allowing different AI services to access and work collaboratively with the information they are authorized to provide.
According to the report, if the simplest words are used to describe Project Pantheon, it is more like a “second brain”. Unlike Recall, which automatically builds a complete historical record by continuously intercepting screen snapshots, Pantheon emphasizes that it is up to the user to decide what information to keep and then use artificial intelligence to help organize, retrieve and understand the content.
Currently, Microsoft has not officially announced the publish time, business plan or final product name of Project Pantheon. However, in terms of the functions that have come to light, it appears that the company is exploring an AI information management programme with more privacy-control capabilities than Recall, in the hope of helping users to build a personal knowledge base while avoiding disputes arising from continuous screen recording.
