Brave's AI assistant Leo is now available to all desktop users, offering context-aware requests and features like summarizing webpages or videos and translating text. A paid version called Leo Premium is also released, offering access to faster and better large language models (LLMs) and higher-rate limits for $15 per month. Brave joins other browsers like Opera and Microsoft Edge in incorporating AI assistants, but will need to innovate further to monetize and generate revenue.
