Turn public complaints into named leads with one plain-language query
Search Reddit, X, LinkedIn, TikTok captions, Hacker News, Indie Hackers, Product Hunt, and public Discord servers from one query.
Enter the problem you solve in everyday language and get people who complain about, recommend, or seek alternatives — not keyword-matched noise.
Each row carries the username, the exact quote, the source URL, the platform, and the posting date, so your outreach can reference what the person actually wrote.
Push lists into Clay, Apollo, HubSpot, or Notion, or pull them programmatically with a read-only API and webhooks on higher tiers.
