Brave Leo

Brave Leo is the AI assistant built into the Brave browser. You chat with it without leaving the tab you are on, asking it to summarize webpages, generate content, translate, and analyze text. Leo is designed around privacy: Brave says Leo does not retain or share chats, does not use them for additional model training, and requires no account or login to start chatting. Leo works with the material in front of you. It can analyze PDFs, Google Docs, and Google Sheets to pull out the information you need, and it uses Brave Search to enhance answers with richer details and up-to-date information. From the FAQ, Leo can also create content such as articles, essays, and emails, translate between languages, and offer coding help with suggested and sample code for software applications and database queries. On iOS, you can ask Leo questions by voice-to-text instead of typing. Several controls shape everyday use. You can set preferences for Leo to remember across chats, so responses become more contextual and tailored while privacy is maintained. Temporary chats do not appear in your history and are deleted instantly when closed, while regular chat history is saved locally on your device so you can revisit or continue a conversation later through the full-page view or the browser sidebar. Leo can also help organize tabs, grouping tabs for a specific topic or gathering them in a new window. Access is direct: type in the address bar and choose Ask Leo, or use the Leo icon in the toolbar on desktop or the browser menu on mobile. Leo is available in the Brave browser on desktop for macOS, Windows, and Linux, and on mobile for Android and iOS. A Bring Your Own Model feature lets you run your own local or remote models, or connect to third-party APIs, for more control over your interactions. Brave notes that the browser sends your latest prompt, the context of the current conversation, and, when a task requires it, context from the page you are viewing, and that no personal data is retained and conversations are not persisted for training. Brave also advises double-checking Leo responses for accuracy, as with any AI assistant.
