A CLI tool for Substack writers. Schedule notes from your terminal, Claude Desktop, or Claude Code — they post themselves at exactly the right time.
Built for writers who ship
Add a note and it's submitted to Substack's scheduler within 60 seconds. StackCLI captures; Substack publishes.
Drop a time after your note — no flags needed. StackCLI picks the right slot and avoids crowding.
Ask Claude Desktop, Cowork, or Claude Code to draft, schedule, and analyse notes for you. StackCLI registers itself automatically.
Ask Claude for a performance summary, search your archive by date or engagement, and refresh stats on demand — all through natural language.
How it works
Run stackcli add in the terminal, ask Claude to write one, or type it inline with a time — morning, friday, or an exact datetime.
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.
Your note goes live on time. StackCLI archives it and auto-likes it. Your queue stays clean and your mind stays clear.
A menubar app for macOS. Just your notes, posted on time.
