With this plugin you can ask ChatGPT to:\n\n- Browse your Notes by status or tag (drafts, scheduled, published) and open any note in full.\n- Draft new Notes in your own voice and save them to WriteStack as drafts. It reads your saved writing style first.\n- Check your posting queue, your next open slots and how many more notes your plan lets you schedule, then schedule notes for the next slots or for dates you choose.\n- Review how your published Notes performed (impressions, reactions, restacks, subscribers gained) and see recent comments and mentions on your Substack.\n- List, create and update your articles, generate an article draft, and push or schedule it to Substack.\n\nActions that overwrite content or schedule posts are flagged before they run, and the plugin does not delete anything. It needs a WriteStack account with MCP access enabled. Sign in with your WriteStack account when ChatGPT asks you to connect.",
