FAQs about Search API

What can Brave Leo do?

Ask Leo to summarize a webpage you’re viewing. Or ask questions about the page, and get answers, clarifications, and other viewpoints. Brave Leo can also create content, translate between different languages, and transcribe audio and video. It can even have back-and-forth conversations.

What platforms is Leo available on? Can I try Leo on mobile?

Brave Leo is currently available in the Brave browser for desktop (macOS, Windows and Linux). Leo will be available on the Brave browser for mobile (Android and iOS) very soon.

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

The Brave browser shares with the server your latest query, the context of your current conversation and, when the use case calls for it, the necessary context from the page you’re viewing (e.g. an article’s text, or a YouTube video’s transcript). Note that once a chat is closed all record of it is erased.

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 and access to even better models.

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

No, 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 say, and the premium experience remains private and anonymous. 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 and they are discarded immediately after a response has been generated.

Where can I see the history of my chat with Brave Leo?

There’s no way to review past conversations or delete that data—it isn’t stored in the first place. Prompts—and Brave Leo’s responses to those prompts—are immediately discarded when a chat is closed. Personally identifiable information (PII) is never transmitted to Brave servers or any third parties.

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.
