Schedule Substack Notes, see what actually grows your subscribers, and write in your voice with an AI coach, all in one place. WriteStack is the Substack growth platform for writers who want to build an audience without living inside the app. Batch-schedule your Notes, see which ones turn readers into subscribers, clear your notifications in minutes, and let Quill, your built-in AI coach, draft in your voice. Loved by 4,000+ Substack creators, including 100+ bestsellers. WHAT YOU CAN DO Schedule and manage Notes in bulk Import your drafts, schedule or unschedule dozens of Notes at once, reorder your queue, and organize everything with tags and evergreen queues. Pick an exact date and time, or drop a Note into your queue and let it fill the next open slot. Meet Quill, your Substack coach Ask Quill to turn a post into Notes, fill next week's slots, or explain a dip in impressions. It drafts in your voice, schedules to Substack (and to LinkedIn and X), and answers using your own stats. It's built on patterns from millions of Notes and posts, with playbooks for growth, titles, SEO and paid subscribers. Nothing gets scheduled without your approval. See what actually grows your Substack Substack buries your Note stats. WriteStack puts them in one dashboard, so you can see which Notes turned readers into free and paid subscribers, connect growth to your posting habits, and write more of what works. Notes that sound like you, not like AI WriteStack learns from your published content, your writing style and your personal prompt. Turn any article or rough idea into ready-to-queue Notes you'd actually publish. Post when your audience is online Write when inspiration hits. WriteStack shows when your readers are most active so your Notes go out when they're scrolling, which is especially useful if your audience is in a different time zone. Write once, post everywhere Connect Buffer once and send your Notes to X, LinkedIn, Bluesky and more from the same schedule. Clear your notifications in minutes The Activity Center filters Substack's noise down to the comments, mentions and replies that matter. Keyboard shortcuts and auto-clearing items turn a long chore into a short daily pass. Build a feed of the creators who matter Create shareable lists of the writers you want to engage with (your community, clients or favorite creators), see their latest Notes, and reply without leaving WriteStack.
