Brave Brings Leo AI to Android

Brave today released a new version of its web browser on Android that includes the firm’s privacy-focused Leo AI assistant.

“Brave is excited to announce the release of Leo—Brave’s privacy-preserving AI assistant built right into the browser—on all Android devices,” the announcement post notes. “Android users who update to version 1.63 can ask Leo questions, summarize pages, translate pages, create content, and more from both the browser address bar and within the webpage.”

Brave launched Leo in its desktop web browsers back in November, and it has since improved the AI assistant with performance and accuracy improvements related to the Mixtral LLM and PDF and Google Docs integration. Today, Leo lets desktop Brave users ask questions in general or about the web page they’re viewing, generate summaries, generate new content, translate pages, create video transcriptions, and write software code. And with its expansion to Android, now users can interact with this private AI functionality on the go.

Leo in Brave for Android can do much of what the desktop version does, but Brave calls out some activities that might be well suited to mobile, like summarizing long web pages, getting product comparisons, and helping with recipes and travel plans. As with Leo on desktop, Leo in Brave for Android comes with Brave’s privacy and security guarantees—all requests are proxied through an anonymization server, no personal data is retained, and Brave doesn’t use your data for training—and there’s no login or signup required.

You can, however, optionally sign up for Leo Premium for $14.99 per month and get higher rate limits in each of the LLMs it supports—Mixtral 8x7B, Claude Instant, and Llama 2 13B—and higher conversation quality.

You can learn more on the Brave Leo website. But, yes, Brave plans to bring Leo to its browser on iOS as well, and to delivery functional parity for Leo between desktop and mobile.
