X Smart Search is a Chrome extension designed to enhance search functionality within the X social network. The extension simplifies the process of applying advanced search filters by utilizing special tags specific to X. It employs LLM technology to interpret user queries and automatically suggests appropriate advanced search filters. For instance, complex search queries like "tweets by elon musk last week with only images" are transformed into X-compatible formats such as "filter:images from:elonmusk since:until:."

Smart Search recognizes various filter criteria, including posts with images, media, links, quote tweets, replies to or from specific users, links to particular domains, posts near certain locations, within specific time frames, and with designated numbers of likes, retweets, and replies.
