Windsurf Browser

Phi Browser is an AI-native web browser designed to act as an intelligent, proactive companion that learns user behavior and assists with tasks directly within the browsing experience. Built on the Chromium engine, it functions as a full, fast, and stable browser while maintaining an open-source core for transparency and reliability. It introduces a personalized AI system based on a unified memory layer that remembers user activity, habits, and context, allowing it to anticipate needs and prepare actions without requiring repeated prompts. Rather than relying on a generic assistant, Phi offers a customizable, user-specific AI that adapts over time and proactively suggests or executes tasks such as navigating pages, summarizing content, or managing workflows. It emphasizes “less prompting, more doing,” meaning the browser can automate repetitive actions like clicking, typing, and navigating while maintaining accountability by showing what it has done.
