Substack Autopilot — Designed for Writers

Schedule and auto-publish your Substack Notes with AI writing assistance. Write, queue, and post notes at the perfect time.

Kalemly is a productivity toolkit for Substack creators. It adds advanced scheduling, AI content generation, and automation features directly to the Substack Notes interface. Core Functionality: AI Note Generation: Connect your OpenAI or Gemini API keys to generate growth-focused Notes using custom "Strategist" prompts. Smart Scheduling: Queue multiple Notes for future publication. The extension uses the Chrome Alarms API to track your schedule locally. Native Automation: Automates the Substack composer by injecting text and interacting with the native "Schedule" and "Post" buttons. Queue Management: View, edit, or delete upcoming drafts in a dedicated "Upcoming" dashboard. Analytics: Monitor engagement metrics through an integrated stats overlay. Reliability: Uses the Power API to ensure your system stays awake for critical scheduled posting windows. How it works: Open the extension on substack.com/notes. Draft a Note (or use the AI generator). Select a date/time and click Schedule. Use Schedule All Now to automate the final delivery to the platform.
