Brave Leo is a privacy-first AI assistant built directly into the Brave browser, answering questions about pages without collecting or selling your data.
Leo lives in the Brave sidebar and can summarize pages and videos, translate passages, explain code, and answer follow-up questions grounded in whatever you are viewing. Privacy is the differentiator: conversations are not logged, proxied requests strip identifying information, and premium subscribers can route queries to their own model providers through Brave’s Proxy API. The assistant works across mobile and desktop Brave builds, and its knowledge extends to Brave’s independent search index for current-events questions. Because Leo is integrated at the browser level, it can reference page context automatically, saving the copy-paste dance that web chatbots demand. The free tier uses capable default models, while Premium unlocks larger models and higher limits. Leo’s free tier is generous enough for daily summarization and translation, and because Brave blocks trackers by default, the pages the assistant reads arrive stripped of the ad-tech noise that often confuses page-analysis tools.
Leo is free inside Brave with standard models and daily limits. Leo Premium costs a monthly fee, unlocking larger models, higher usage, and the ability to connect external providers such as Anthropic or Mistral through Brave’s privacy proxy.
Privacy-conscious users who want page-aware AI assistance without feeding a data-hungry ecosystem, and Brave users who prefer keeping research, browsing, and AI in one trusted application. Journalists, researchers, and anyone handling sensitive material in the browser will appreciate that assistant usage does not create a behavioral profile for advertisers.
