What is Brave Leo?


Leo, Brave
ORG

’s browser AI assistant, can help with all sorts of tasks. It can create real-time summaries of webpages or videos. It can answer questions about content, or generate new content. It can even translate pages, analyze them, rewrite them, and more. Whether you’re looking for information, trying to solve a problem, or creating content,

Leo
PERSON

can help.


Leo
PERSON

combines this easy, free access to AI with the privacy focus of Brave. Chats with

Leo
PERSON

are private, anonymous, and secure.

Leo
PERSON

doesn’t record chats, or use them for model training, and no account or login is required to use

Leo
PERSON

. With cutting-edge technology and privacy,

Brave Leo
PERSON

pushes the boundaries of typical

AI
ORG

chatbot services.

“It is increasingly common

today
DATE

to use AI to ask questions and get assistance. AI can be a powerful tool but it can also present growing concerns for data privacy and there’s a need for a privacy-

first
ORDINAL

solution,” said

Brian Bondy
PERSON

, CTO and co-founder of Brave. “Brave is committed to pairing AI with user privacy, and will provide our users with secure and personalized AI assistance where they already spend their time online. We’re also thrilled to work with

Anthropic
ORG

to bring

Claude
PERSON

’s exceptional conversational abilities to

the millions of Brave
MONEY

users worldwide.”

Introducing Leo Premium

By default,

Brave Leo
ORG

is free for all users, with easy access to the

Llama 2
LAW

large language model from

Meta
ORG

. For users who want additional models, Brave is also releasing a premium version of

Leo
PERSON

for $

15/month
DATE

.

Leo Premium
PERSON

subscribers will get access to

Claude Instant
PERSON

,

Anthropic
ORG

’s faster and lighter model that excels at logical reasoning and coding. The current version of

Claude
PERSON

produces longer, more structured responses, follows instructions better than previous versions of Instant, and shows improvements in math, coding, multilingual abilities, and question answering. Additional models will be available to

Leo Premium
ORG

users, as well as access to higher rate limits, higher-quality conversations, priority queuing during periods of peak usage, and early access to new features and improvements.

This integration represents a milestone in delivering sophisticated natural language conversations powered by AI directly within the browser environment. With

Claude
PERSON

’s advanced capabilities and

Brave
ORG

’s focus on user privacy and control, we hope to set a new standard for helpful, responsible, and context sensitive AI interactions. Anthropic used Brave’s Search API to train their latest model,

Claude 2
PERSON

, on high-quality data to help optimize

Claude
PERSON

’s outputs for retrieval augmented generation (RAG) queries.

“We’re excited that Brave is going to bring our state-of-the-art large language model

Claude
PERSON

Instant directly into their browser. Integrating access to

Claude
PERSON

seamlessly within

Brave
ORG

gives users assistance whenever they need it, right in the context of the page they are on,” says

Matt Bell
PERSON

, Head of Product Research at Anthropic. “

Whether Brave
WORK_OF_ART

users are analyzing text, editing documents, or writing code, they can now benefit from having personalized help from

Claude
PERSON

at any time. This integration unlocks the potential for AI to enhance people’s browsing and productivity in an intuitive, contextual way.”

Brave Leo and unparalleled privacy

As a privacy-

first
ORDINAL

company,

Brave
ORG

is dedicated to releasing leading alternatives to popular Web tools that also protect user data and anonymity.

Leo
PERSON

is no different:

Reverse proxy : All requests are proxied through an anonymized server so the request and user-address cannot be linked. Brave cannot associate the user request with their IP address.

Immediate discarding of responses : Conversations are not persisted on

Brave
ORG

’s servers. Responses from

Leo
PERSON

are discarded immediately after they’re generated, and not used for model training. We do not collect identifiers such as your IP Address that can be linked to you. No personal data is retained by the

AI
ORG

model or any

3rd
ORDINAL

-party model providers.

No login or account required for access : Users do not need to create a Brave account to use

Leo
PERSON

.


Unlinkable
ORG

subscription: If you sign up for

Leo Premium
PERSON

, you’re issued unlinkable tokens that validate your subscription when using

Leo
PERSON

. This means that Brave can never connect your purchase details with your usage of the product, an extra step that ensures your activity is private to you and only you. The email you used to create your account is unlinkable to your day-to-day use of

Leo
PERSON

, making this a uniquely private credentialing experience.

Leo
WORK_OF_ART
