Brave Leo is an AI assistant built directly into the Brave browser, giving users instant access to AI-powered assistance without leaving the web page they are currently viewing. Initially introduced through the Brave Nightly desktop channel for testing and feedback, Leo is available from the Brave Sidebar, allowing users to ask questions, summarise content, and interact with web pages in a seamless browsing experience. Leo can generate video transcripts, create interactive summaries of articles, explain complex topics, and help users better understand the information they are reading. It functions as a conversational chatbot, answering questions, providing explanations, and even suggesting relevant follow-up questions to make research and learning more efficient. Powered by Meta's Llama 2 language model, Leo delivers intelligent responses while maintaining Brave's strong commitment to user privacy. Unlike many AI assistants, Leo is designed with privacy as a core feature. User requests are submitted anonymously through a reverse-proxy, helping prevent personal information from being linked to AI interactions. No login or user account is required to access Leo, and conversations are not stored or used to train AI models. After a response is generated, chats are immediately discarded, ensuring a higher level of anonymity and data protection. Users can access Leo directly from the Brave Sidebar while using the Brave browser, making it easy to summarise pages, understand difficult content, or quickly find answers without switching tabs or copying text into another application. Brave also encourages users to share feedback with its community to help improve Leo during development. Overall, Brave Leo combines the convenience of an AI-powered browsing assistant with Brave's privacy-first philosophy. By offering fast summaries, intelligent conversations, and useful reading assistance directly inside the browser, Leo provides a practical AI experience while giving users.
