PostSnag is a Chrome extension for researching public Facebook content. While you browse a profile, Page, creator account, or Facebook Group, it captures the posts and reels that appear on screen and sends selected content to a dashboard. The product is designed for marketers, creators, strategists, and researchers who need to study what performs without saving posts manually or relying only on Facebook's native feed.
The dashboard brings captured content together for sorting, ranking, bookmarking, and analysis. Users can compare visible metrics such as reactions, comments, shares, video plays, post type, caption, and posting time. A Discovery feed surfaces outliers across tracked profiles, while exports in JSON, Markdown, or Excel can be used for further analysis in tools such as ChatGPT, Claude, or Gemini.
