Phi
Phi is a macOS web browser with built-in AI features, local-first data handling, and a native interface for everyday browsing and assisted tasks.
What is Phi?
Phi is a web browser for macOS designed to combine everyday browsing with built-in AI assistance. It is made by Phinomenon Inc. and uses the Chromium engine while presenting a native Mac interface. Phi is aimed at people who want a browser that can help with routine online tasks, chat-based assistance, and personalized workflows while keeping core browsing familiar. Its published product information highlights local-first data handling on the Mac, multiple layout modes, and an interface built for Apple Silicon Macs. Users may encounter Phi as an alternative to mainstream browsers when they want integrated AI tools inside the browsing experience rather than as a separate app or extension. For Mac users, its main role is web access, tab management, and AI-assisted browsing in one desktop application.

Safety overview
Status: Mostly safe
Phi is a legitimate web browser, so it may handle browsing history, downloads, saved site data, and account information as part of normal use. If you sign in or use its AI features, some requests and account-related data may be sent to the service to provide those features, while the product also describes local-first handling for core use on the Mac. As with any browser, only grant access you expect, review privacy settings, and use trusted websites and downloads.
Recommendation: Keep Phi if you use it as one of your browsers or rely on its built-in AI features. If you do not use it, removing the app is reasonable, but doing so will also remove access to its saved app-specific settings and browsing workspace unless you back them up first.
