FAQ

What can Brave Leo do?

Ask Leo to summarize a webpage, doc, or PDF. Or ask almost any question in general, and get answers, summaries, clarifications, related information, and other viewpoints.

On iOS, you can also ask Leo questions without typing on your phone via voice-to-text.

Can I use my own models in Leo?

Yes, you can use your own models in Brave Leo, with a feature called Bring Your Own Model (BYOM). Check out our BYOM help center guide to learn more about using local or remote models, or even connecting to third-party APIs.

What data does the Brave browser send to the servers that power Leo?

With respect to the servers that power Brave Leo, your browser will share your latest prompt, the context of your current conversation, and—when the use case requires it—the necessary context from the page you’re viewing. We do not collect identifiers that can be linked to you (such as IP Address), and no personal data is retained.

Does Brave Leo have a daily limit on the number of prompts I can send?

Brave Leo may be more or less accessible depending on traffic levels and usage. You can subscribe to Brave Leo Premium to get higher usage limits.

Do I need to sign up for a Brave account to use Brave Leo?

No account or signup is required to access the free Brave Leo experience. Leo Premium subscribers will have to create a Premium account, but this is only to verify premium access. There is no Leo account per se, and the premium experience remains private. Your premium account is completely unlinkable to any usage of Leo itself.

Will you use my conversations for model training?

No. Your conversations are not persisted for model training.

Can I access a history of my chats with Leo?

Yes, regardless of which models you choose chat history can be stored locally on your device, and referred back to later. You can review past conversations through the Leo full-page view, or through the browser sidebar.

To access chat history via full-page view, navigate to brave://leo-ai, browse through your chat history in the left column, then select any conversation to view it or to continue it.

To access chat history via the browser sidebar, click the Leo icon in the sidebar, select the “…” menu, choose Conversation history, then select any conversation to view it or to continue it.

Learn more about accessing, deleting, or disabling chat history.

Can I trust Leo’s replies?

As with any AI, Leo’s responses may contain misleading information and/or factual inaccuracies. Additionally, bias and/or harmful content present in the data during training may on some occasions be reflected in the model’s outputs. We recommend double-checking any Leo responses for accuracy.

Please also provide feedback to us if you see anything concerning. To do so, click the menu next to Leo’s response and select the best option.

Does Leo hallucinate?

Yes, it does. Hallucinations are an intrinsic challenge in how LLMs work. Sometimes regenerating the answer may help. Always double-check Leo’s responses (for example, try the same query on Brave Search) before quoting them.
