Zephium

Zephium is a free, open-source web browser and AI-powered workspace designed to combine everyday browsing with automated workflows. Built with Rust, it uses native web engines rather than maintaining a separate Chromium or Firefox fork. The browser includes advertisement blocking, tracker protection, Chrome extension support, and customizable vertical tabs. Its integrated AI assistant can analyze web pages, answer questions, and perform browsing actions. A dedicated Work canvas coordinates AI agents that research, compare information, and execute multistep tasks. Zephium also provides built-in notes, task management, and focus tracking. Available for Windows and macOS, it emphasizes lightweight performance, local data storage, and user-controlled AI automation.
