Brave, the privacy-focused web browser, has unveiled its AI-driven assistant, Leo, extending its availability to all Android users. The multifaceted assistant empowers users to inquire, translate pages, summarize content, generate content, and more. This Android debut follows Brave's initial introduction of Leo on desktop platforms a few months earlier. According to Brave, Leo will soon be accessible on iOS devices in the forthcoming weeks. Brave emphasizes Leo's commitment to privacy, asserting that all interactions with Leo remain confidential, with no recording or utilization of chats for model training. Requests are routed through an anonymization server, and Leo's responses are discarded once generated. Additionally, users are not obligated to create a Brave account to leverage Leo's capabilities. For those opting for a subscription, Brave assures anonymity through unlinkable tokens, ensuring the company remains unaware of user activities or email addresses.

To initiate Leo on Android, users simply open the browser, initiate a query in the address bar, and click on "Ask Leo." Alternatively, for an on-page chat experience, users can access Leo by selecting the three-dot menu and tapping on "Leo." Leo offers a plethora of functionalities including real-time page/video summaries, content inquiries, content generation, translation, transcription, and coding assistance. With Leo's diverse features, Brave aims to position itself as a one-stop solution for users, minimizing reliance on other language model services like ChatGPT.Leo facilitates various tasks such as meal planning, travel recommendations, product comparisons, and summarizing lengthy web content, catering to users' diverse needs and time constraints.

Incorporating access to Mixtral 8x7B, Anthropic's Claude Instant, and Meta's Llama 2 13B, Leo offers flexibility and customization. While Mixtral 8x7B serves as the default language model for Leo on desktop and Android, users have the option to choose alternative models or upgrade to Leo Premium for enhanced rate limits at $14.99 per month. This subscription covers up to five devices across Android, Linux, macOS, and Windows platforms. Android users can access Leo by updating to version 1.63, with a phased rollout planned over the next few days. Brave's introduction of Leo echoes recent efforts by other browser companies, with Opera unveiling its AI assistant, Aria, in collaboration with OpenAI last year. Aria adopts a chatbot-like interface, enabling users to pose queries and receive prompt responses, reflecting the growing integration of AI technology within web browsing experiences.
