AI assistants collect personal information, store your conversations on their servers and use your inputs to train their models. Leo doesn't. Here's how we built privacy into every part of the Brave browser's AI assistant...

All of the AI models offered through Leo are hosted on our own infrastructure to ensure user privacy. We don’t retain your conversations with Leo or use them for model training. We also don’t collect any personal data such as your IP address.

This same approach applies to any documents or images you ask Leo to analyze. They’re discarded immediately after Leo answers your prompt. Other companies retain these files on their servers.

You don't have to create an account to chat with Leo for free. If you buy Leo Premium, which offers higher rate limits + extra models, your privacy is also protected in the subscription process. Subscribers get unlinkable tokens so payment info can’t be used to identify usage.

If you want to use models not normally offered by Leo and want to protect your privacy, use the Bring Your Own Model (BYOM) feature. BYOM lets you run a model on your own device and connect it to Leo to ensure that none of your data leaves your device.

We’re currently building new AI innovations that could dramatically change how you browse. One thing won’t change, though: Brave will remain the safest way to use AI.
