WriteStack: Substack Notes Scheduler & Analytics

Schedule Substack Notes in advance, batch your writing, queue posts, and see which notes actually grow your Substack.

Schedule Substack Notes in advance — and finally post consistently without living inside the app. WriteStack is a Substack Notes scheduler and analytics tool for writers who want to grow their subscribers without spending all day on the platform. Write your Notes in one sitting, queue them up, and let WriteStack publish them at the times your audience is actually online. Loved by thousands of Substack creators. WHAT YOU CAN DO Schedule Substack Notes Substack has no native scheduling for Notes. WriteStack adds it. Pick an exact date and time, or drop a Note into your queue and let it fill the next open slot automatically. Batch your writing Write ten Notes on Sunday, schedule them across the week, and stop opening Substack five times a day just to stay visible. Consistency is what compounds on Notes — batching is how you get it without the daily grind. Post when your audience is actually there WriteStack looks at your audience activity and recommends the posting windows that get you the most reach, instead of making you guess. Especially useful if you write from a different time zone than most of your readers. See what actually grows your Substack Track likes, comments and restacks on every Note — and, more importantly, see which Notes turned into subscribers. Stop guessing which style of Note is working and start repeating the ones that do. Turn any article into Notes with one click The built-in AI is trained on high-performing Notes and writes in your voice. Paste an article or an old post and get Notes you'd actually publish, ready to edit and schedule. Clear your notifications in minutes The Activity Center pulls your notifications and replies into one place, so you can answer everything in one pass instead of scrolling the app looking for what needs a response. Full formatting, images, links and mentions Scheduled Notes publish exactly the way you wrote them — images, formatting, links and @mentions all intact. Nothing gets flattened. WHO IT'S FOR - Substack writers who publish Notes regularly and want to stay consistent - Newsletter creators trying to grow their subscriber count from Notes - Writers whose audience is in a different time zone - Anyone who'd rather batch a week of content than post live every day - Publications and teams coordinating Notes across a content calendar HOW IT WORKS 1. Install the extension and pin it to your toolbar. 2. Connect your Substack profile in one click — no API keys, no complicated setup. 3. Write your Notes and schedule them, or add them to your queue. 4. Keep Chrome open at the scheduled time. Substack has no public API for Notes, so WriteStack publishes from your own browser session — which also means your Notes post as you, natively, exactly like you'd typed them yourself. PRICING There's a free plan you can use for as long as you like, plus a 7-day trial of the paid plan if you want scheduling, analytics and AI without limits. PRIVACY WriteStack only runs on Substack.
