About the startup

Zettelcasting helps you capitalize on the thinking you have already done. It reads the notes in digital vault of your favorite PKM tool (Obsidian, Capacities, Craft, or Heptabase) and transforms them into finished posts, newsletters, and social media threads. You can automate your content workflow by scheduling these pieces to publish directly to platforms including Ghost, Beehiiv, X, LinkedIn and Facebook on a timeline that works for you. Zettelcasting is an "MCP-first" product, and you can easily use ChatGPT, Claude, or any AI tool that uses MCP servers to write and schedule your posts. Our analytics dashboard monitors your posts for interaction signals. Bring your own AI API key, and you can set Zettelcasting to format your post for the platform you choose to post to. Free 30 day trial, no credit card needed.
