Brave just announced that it is now exclusively using its own index for its search engine. In other words, it doesn’t rely on third-party solutions like Bing anymore.

When the company launched Brave Search in 2021, it mentioned that it relied on other providers for nearly 13% of its queries. A year later, that number was slashed to 7%.
