What is Brave Leo?

Brave Leo is the assistant built into the Brave browser, so the chat panel sits next to the page you are already reading instead of in a separate tab. It summarises the current page, answers questions about its content, translates a selection and rewrites text, with a choice of underlying models. By default chats are not used for model training and are not linked to an account, which is the main difference from standalone assistants. Paid plans add faster models and answers that cite live web sources. It is a convenience assistant for people who already use Brave rather than a destination product in its own right.

FAQ

Do I need an account to use Leo?

No. The assistant works in the browser without signing in, and chats are kept on the device by default. Signing in matters only for paid model tiers or for settings that follow you between devices.

Which models does it use?

Brave offers a small menu of models, mixing open-weight options with faster hosted ones on paid plans. The exact list changes over time, so treat the model choice as a setting rather than a fixed feature.

Does it send my pages to a server?

Page content is sent to the model provider to answer your question, so the usual rule applies: do not ask about anything you would not paste into a third-party chat tool.
