morning tonight tomorrow friday

Works with Claude

Ask Claude Desktop, Cowork, or Claude Code to draft and schedule notes for you. StackCLI registers itself automatically.

How it works

From thought to
scheduled draft in seconds.

1

Schedule a note

Run stackcli add in the terminal, ask Claude to write one, or type it inline with a time — morning, friday, or an exact datetime.

2

Substack gets a scheduled draft

Within 60 seconds, the menubar app sends your note to Substack's own scheduler. It's Substack doing the publishing — reliably, at exactly the time you set.

3

It publishes itself. You move on.

Your note goes live on time. StackCLI archives it and auto-likes it. Your queue stays clean and your mind stays clear.

Always in the background,
never in the way

Lives in your menubar. Posts while you work.
