AO3 Primary Ship Search is a Firefox add-on designed to streamline your search experience on Archive of Our Own (AO3). By adding a simple checkbox to the search page, it allows users to filter results to show only those stories where the specified ship tag is the first relationship tag. This feature is particularly useful for users who want to avoid results cluttered with stories focused on other ships, ensuring that the search results are more relevant to their interests.

While using this add-on may result in fewer search results per page, it effectively prioritizes stories that align closely with the user's specified ship. The add-on also accommodates multiple ship tags, returning any story that includes one of the specified tags as the primary focus. Although it can't guarantee every story will feature the ship prominently, it leverages common tagging practices to improve search outcomes.
