StackBuddy is a genuinely well-designed scheduling tool. Its queue view is clean and the time-slot system is intuitive. Its free Chrome extension hands your scheduled Notes to Substack's own scheduler, and Substack publishes them.
The free plan includes 30 scheduled Notes a month, 10 AI credits and the full creator network, and Pro costs $15 a month. For a writer on a budget, that is a strong offer.
