Giststack

Giststack is a content research and drafting tool for professionals who want to build a personal brand without spending hours turning saved articles into posts. It addresses a common gap: people follow industry newsletters, blogs, and YouTube channels, but a saved link is not a point of view. Giststack provides a repeatable path from keeping up with sources to publishing commentary worth reading.

The product works in three stages. First, it gathers followed newsletters, websites, and YouTube channels into a single reader. Second, it extracts insights from individual posts and identifies broader themes, called stories, that appear across multiple sources. Third, it turns a chosen insight into a draft — a social post, video script, newsletter, or longer article — shaped by an editable Brand Profile and writing persona that describes the user's audience and expertise. Users add their own perspective before generating, so the final draft reflects their judgment. Giststack was created by Chris Closset, who shares updates on X, LinkedIn, and YouTube.
