Whitematterlabs offers PAI, a personal AI assistant designed to automate routine digital tasks by interacting directly with a user's mail, calendar, browser, and files. PAI is intended for individuals seeking an assistant that learns their work habits, remembers relevant information, and proactively manages busywork, allowing users to focus on more important activities. The tool emphasizes maintaining user context and operates within the applications people already use, aiming to reduce repetitive explanations and streamline digital workflows.
PAI is delivered as a local application that runs entirely on the user's own machine. It does not rely on remote servers or external datacenters; instead, all learned context and data are stored as plain files on the user's disk. This approach gives users full ownership and control over their data, making it readable, portable, and easy to back up or delete. The assistant performs actions in mail, messages, browser, and files using the same interface methods as the user, handling tasks from start to finish rather than just offering suggestions.
A core principle of PAI is user safety and transparency. The assistant always shows what it has found, asks for confirmation before sending or changing anything, and keeps users informed throughout its processes. Users retain final authority over all actions, ensuring that the assistant does not operate autonomously without oversight.
PAI is free and open source, with no pricing, login requirements, or paid tiers. The source code is fully available for audit or modification, allowing users to examine its behavior or adapt it to their preferences. Installation is performed via a terminal command, and users are encouraged to review the installation script beforehand. Whitematterlabs positions PAI as part of a vision for the future of personal computing, with a focus on privacy, transparency, and user empowerment.
