They recently added a chatbot that runs locally they call Leo based on llama2. It's pretty impressive that you can perform LLM tasks on the current page without the use of any 3rd party service. And of course you can pay them for the souped up version. https://brave.com/leo-release/
Feels like I am alone in thinking the crypto features of Brave are cool. And not because I think that industry generally isn't full of slime. But micropayments for content has been a good, latent idea for a generation, and here they've simply built it as a default feature.
I still use FF and Brave equally because of my experience with the first browser wars and my mistrust of Chrome, having become the new IE.
