Phi 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.

Aside
Aside is an AI browser rebuilt for people and agents, designed to complete real work across the websites, accounts, tabs, messages, and files users already rely on. Unlike agents that depend on integrations, Aside operates websites directly, signing into email, dashboards, internal tools, and other logged-in services to handle research, communications, document work, spreadsheets, downloads, forms, and multi-step workflows. Users can assign a task from any tab, provide page context with mentions, and let the agent keep working through follow-ups with Ultrabrowse until the task is done. Aside can prepare staff packets, collect dashboard metrics, download and rename invoices, check vendor renewals, stage approval notes, contact support, capture screenshots, and return source links and exceptions for human review. Repeated processes can become scheduled Routines or reusable Skills with specific portals, naming rules, approval stops, and instructions.

Browser Use
Browser Use is an open source Python library that enables AI agents to interact seamlessly with web browsers. Combining advanced AI capabilities with robust browser automation allows AI agents to perform tasks such as applying for jobs, visiting links, extracting information, and answering messages on platforms like WhatsApp. The library supports multiple large language models, including GPT-4, Claude 3, and Llama 2, facilitating complex web operations through a simple interface. Key features include visual recognition combined with HTML structure extraction for comprehensive web interaction, automatic multi-tab management for handling complex workflows, element tracking by extracting XPaths of clicked elements to repeat exact LLM actions, and the ability to add custom actions like saving to files, database operations, notifications, or human input handling. Browser Use also incorporates intelligent error handling and automatic recovery for robust automation workflows.

Polar Browser
Polar is an AI browser that actually does work for you, turning words into quick or hours-long tasks across research, recruiting, sales, operations, marketing, email, data and running a business. Built as a Chromium browser, it works inside the websites, accounts, sessions, extensions, and tools users rely on, clicking, typing, navigating, reading pages, updating spreadsheets, filling forms, and following tasks through to completion. Users can hand off work from any tab, use the current page as context, ask a question, or start a longer assignment without switching out of their workflow. Polar can operate autonomously for many hours across multiple sites and difficult interfaces, while users follow along, take over at any time, and keep sensitive decisions in their own hands. Prompts can be saved as reusable workflows and run manually or on hourly, daily, weekly, or custom schedules, carrying the same context into every execution.
