Brave Leo AI: User Agent, robots.txt Rules & Safety Rating

Q: What user-agent string does Brave Leo AI use?

Brave Leo AI is reported to identify itself with Bravebot. That spelling comes from ai.robots.txt, not from Brave, which has not published crawler documentation naming it. Use it in robots.txt as the best available match, and treat a request carrying it as a clue rather than proof of who sent it.

Q: Is Brave Leo AI safe?

Brave Leo AI is rated Safe in this directory, meaning there are no credible public reports of abusive crawling under this name. It is a Reported token: Brave has not published documentation for it, so its purpose, crawl rate and robots.txt behaviour are not confirmed by the operator, and anyone can send the same user-agent string. Allow or block it on its stated purpose, and back the robots.txt rule with a firewall rule if the traffic matters to you.

Q: Will blocking Brave Leo AI hurt my SEO?

✅ No SEO Impact - Blocking Brave Leo AI does not affect your rankings in Google, Bing, or any other search engine. Brave Leo AI is an AI crawler, not a traditional search indexer. You can freely block it via User-agent / Disallow: / without any SEO penalty.

Q: How do I block Brave Leo AI in robots.txt?

Add the following lines to your /robots.txt file: User-agent: Bravebot Disallow: / This instructs Brave Leo AI not to crawl any path on your site. To block only specific sections, replace / with the path (e.g., Disallow: /blog/).

Q: How do I verify if Brave Leo AI is crawling my site?

Search your access logs for Bravebot (for example grep -i "Bravebot" /var/log/nginx/access.log). Because the operator publishes no IP ranges or reverse-DNS pattern, a match shows that something used the name, not that Brave sent it.

Reported, not operator documented

Brave has not published a crawler page that names Bravebot. It is listed here because a credible public source does: ai.robots.txt. Reported name for Brave Search crawling. Brave says its crawler does not advertise a differentiated user-agent.

What that means for you: the robots.txt rule on this page is the best available spelling, and a well-behaved crawler using this string will honour it, but there is no vendor statement of purpose, crawl rate or robots.txt compliance to rely on. Treat a matching request in your logs as a detection clue, not proof of who sent it, and combine the rule with a firewall rule if the traffic matters to you. If the operator publishes documentation, this profile moves to Official docs.

What is Brave Leo AI?

Brave Leo AI is an on-demand AI fetcher operated by Brave. It retrieves a page only when a user explicitly asks an AI assistant or agent to read, summarize, or act on a specific URL. Because it is triggered by real user intent rather than bulk crawling, blocking it mainly prevents users from pulling your content into Brave's assistant.
