Leo is an assistant built into a browser, with nothing kept after the session. Berges AI is a chat you return to, with encrypted history and shaped output.
Brave Leo is the AI assistant inside the Brave browser. It summarizes the page you are on, answers questions about it, and chats, all through an anonymous proxy that Brave says discards conversations immediately after the reply. The free tier runs a mix of open and closed models; Premium adds larger ones. No account is needed, and you can point it at a model running on your own machine.
Berges AI is not in a browser; it is a place you go to think. Conversations are stored encrypted at rest so you can pick them up later, a reasoning model you pick does the work on every turn, and interceptors shape the answer. Two different jobs.
Leo's strength is being where you already are: highlight text on a page, ask, done. Berges AI needs you to paste a link or the text, and in exchange gives you a conversation you can save, continue, export, and delete. If most of your questions are about the page in front of you, Leo is more convenient. If they are about your own work, a standalone chat is easier to live in.
Brave keeps nothing after the reply, which is the strongest possible retention policy and makes long-running work impossible by design. We keep conversations encrypted at rest so you can return to them, and let you delete any of them permanently. Different answers to what a chat is for.
Leo offers a mix, including closed models on Premium and the option to run a local model. Berges AI runs only open-weights models, hosted for you, with a reasoning model on every turn and interceptors that shape the output. Auditable models and controlled output are the product.
By its design, yes: requests go through an anonymous proxy, conversations are discarded after the reply, and no account is needed. Your message still reaches a model provider to be answered, as with any chat.
Yes. Leo is a feature of the Brave browser. Berges AI works in any browser and does not care which one you use.
Both, if you use Brave: Leo for questions about the page you are reading, Berges AI for thinking and writing you want to keep, with answers that skip the filler.
