Brave, the privacy-focused internet browser, has launched Leo, a generative AI tool that utilizes Anthropic's AI model. Leo is available in the Brave Browser for desktop and will soon be available on mobile. The tool can translate, analyze, and rewrite pages, bringing more AI functionality to the browser. Leo is built with flexibility in mind and allows different models to run, with more models to be offered over time. Bondy, Brave's CTO and co-founder, said Leo prioritizes user privacy and will decline to answer what is deemed illegal or dangerous according to Anthropic and Brave's policies.
