Dia AI Browser is an AI-native browser developed by the Arc team. It deeply integrates AI, allowing users to interact with web content via natural language dialogues to achieve smart summarization, creation, and multitasking.
Currently it primarily supports macOS 14+ (M1 chip or newer). The Windows version is open for a waiting list; users can apply for an invite on the official website.
Core features include context-aware AI conversations, multimodal content parsing (web pages, PDFs, videos), a modular skills system, intelligent split-screen and tab management, and natural-language command-based operations.
Safety is a core priority for Dia Browser. It uses a hybrid processing model to balance speed and privacy, offers a bug bounty program, and undergoes regular independent security audits to protect user data.
You need to visit the official website to apply for an invite or join via an existing user invitation. Once eligible, download the corresponding system version to install and use; Arc users can log in with their email directly.
The Skills system provides reusable one-click function modules such as fact-checking, color analysis, and writing optimization. Users can also explore, mix, or share community-created skills to customize their workflows.
