Giststack
Giststack pulls content from newsletters, RSS feeds, YouTube channels, Reddit, and email subscriptions, then turns those insights into social posts written in your voice. It is built for founders, creators, and marketers who want to stay visible on X, LinkedIn, and other platforms without spending hours reading and rewriting source material.
You follow publications inside the app, organize them into stacks, and Giststack surfaces trending topics and summarized story briefs from what you already track. When you are ready to post, it generates platform-specific copy for X, LinkedIn, Facebook, Reddit, or a newsletter draft.
The tool runs on your own API keys through Open Router, Fal AI, or Straico, so you pick the models and control inference costs. Higher lifetime tiers add workspaces, webhook publishing, and higher monthly processing limits for teams managing multiple brands.

Does Giststack schedule posts directly to social networks?
Giststack does not offer native direct posting or scheduling to social networks. Pro and Business lifetime plans include webhook publishing so you can send posts to external automation tools. User reviews on the Giststack site mention pairing the app with tools like Make for final posting.
What content sources can I follow in Giststack?
Giststack supports RSS feeds, email newsletters via a private Giststack email address, YouTube channels (shorts, long-form, and podcasts), and sources such as Reddit, Substack, and Beehiiv shown on the homepage. You organize sources into stacks for easier browsing.
How many publications can I follow on each Giststack plan?
On the lifetime pricing page, Launch LTD follows up to 20 publications, Pro LTD follows up to 50, and Business LTD follows up to 100. Each plan also sets different monthly post processing limits: 800, 2000, and 4500 posts respectively.
What type of social content can Giststack create?
Giststack generates research briefs and social posts tailored to X, LinkedIn, Facebook, Reddit, or newsletter format, according to the How It Works page. Output is written to match your style rather than generic templates.
