Brave Leo AI

What is Brave Leo AI?

Brave Leo is an AI-powered assistant built directly into the Brave browser, designed to make browsing more interactive, productive, and private. Instead of switching between tabs or tools, users can ask questions, summarize webpages, analyze PDFs, generate content, or translate text—all within the same browsing experience. What makes Leo different is its strong focus on privacy. It doesn’t store conversations, use them for model training, or require an account, ensuring that interactions remain anonymous and secure. It also supports multiple AI models and can even work with user-provided models, giving flexibility based on needs. By combining real-time web context with built-in AI capabilities, Brave Leo turns the browser into a powerful, all-in-one productivity assistant.

Brave Leo is available across 5 major platforms including Windows, macOS, Linux, Android, and iOS. Brave Browser serves 120+ million monthly active users and 51 million daily active users worldwide. Leo supports multiple AI models, offers free and premium plans, and works without requiring a login for the free version. Premium users can access higher usage limits and advanced AI models, while one subscription supports up to 5 devices, making it suitable for both personal and professional use.
