Leo lives inside the Brave browser, Brave Software's privacy-focused alternative to Chrome that has operated since 2015, rather than existing as a separate destination site or app a user has to visit deliberately. Opening the browser's side panel gives direct access to the assistant on whatever page is currently open.
Brave's core privacy positioning carries over into Leo specifically: conversations aren't used to train models, and requests get anonymized before reaching the underlying AI providers, an approach consistent with the ad-blocking, tracker-blocking browser it's built into. Users can also choose between several different underlying models, including Meta's Llama and Mistral's models, rather than being locked to one.
A free tier covers standard use with one default model, and a paid tier starting around $14 a month unlocks premium models and higher usage limits. For someone who already uses Brave for its privacy features and wants an AI assistant with the same anonymized, non-training-data approach built directly into the browser, Leo's integration removes the need for a separate chatbot account entirely.
