Brave Search is a search engine developed by Brave Software.
  • Brave Search uses its own web index. As of May 2022, it covered over 10 billion pages and was used to serve 92% of search results without relying on any third-parties, with the remainder being retrieved server-side from the Bing API or (on an opt-in basis) client-side from Google. According to Brave, the index was kept “intentionally smaller than that of Google or Bing” in order to help avoid spam and other low-quality content, with the disadvantage that “Brave Search is not yet as good as Google in recovering long-tail queries.”
  • Brave Search Premium: As of April 2023 Brave Search is an ad-free website, but it will eventually switch to a new model that will include ads and premium users will get an ad-free experience. User data including IP addresses won’t be collected from its users by default. A premium account will be required for opt-in data-collection.
