Brave Leo

Brave Leo is a large language model-based chatbot developed by Brave Software and included with the Brave desktop browser. Released on 2 November 2023, Leo uses the LLaMA 2 LLM from Meta Platforms and the Claude LLM from Anthropic. It can suggest followup questions, and summarize webpages, PDFs, and videos. The answers given by Leo are not saved. Leo has a $15 per month premium version that enables more requests and uses larger LLMs.

In November 2023, the company said versions for iOS and Android would be available "in the coming months".

PCWorld reported that Leo evades questions about US elections.
