Track a topic on X and find the voices driving it

Overview

Founders, marketers and community teams track a topic on X to know which posts on it are taking off and which accounts drive the conversation, so they can watch those accounts or engage with them. By hand, that means searching X, comparing the likes, reposts and views of each post, then opening the profiles of the people who reposted the posts that took off.

Why it's hard

X gives an agent one official way in, and it costs. The X API is pay-per-use: every post read is billed against credits you buy upfront, and you need a developer app to get a key at all. On x.com, the search has no sort by engagement: the Top tab is X's own ranking, and the Latest tab is by time. To see who reposted a post, you open its list of reposts and then each profile, one at a time.

How Reduck does it

Reduck runs the whole loop in your own signed-in session, so you see what you'd actually see. Your agent searches the posts on your topic and gets, for each one, its likes, reposts, replies, quotes, bookmarks and views, plus the author's follower count. It ranks the posts by that engagement, then lists the accounts that reposted the top posts, with their followers, bio, location and website. You get a ranked shortlist of accounts, with a profile for each one.

What your agent does

• Search the latest posts on your topic or keywords
• Rank them by real engagement, not follower count
• Pull the profiles of the accounts driving the conversation
• Return a ranked shortlist of voices to watch or engage
• Re-run it whenever the topic heats up

Who it's for
