Substack Notes Scheduler

Schedule Substack Notes in advance. Compose, queue, and auto-post Notes with images so you stay consistent without being online.

Substack doesn't let you schedule Notes. This extension fixes that.
Write your Notes, pick a date and time, and they post automatically — even when you're away from your screen.

What you can do:

✍️ Compose — Write Notes (280 char limit), attach images, and pick your posting time.

📋 Queue — See everything at a glance: scheduled, posted, failed. Cancel or retry with one click.

📝 Drafts — Save half-finished ideas. Edit and schedule them when you're ready.

⏰ Auto-post — When the time hits, the extension posts your Note via your logged-in Substack session. No third-party servers. No API keys.

🔁 Auto-retry — If a post fails, it retries up to 3 times with 5-minute delays so nothing gets lost.

🔢 Badge — See how many Notes are queued right from your toolbar icon.
Why this exists:

If you're serious about growing on Substack, you need to post Notes consistently — ideally multiple times a day. But you can't be online 24/7. This extension lets you batch your Notes in one sitting and drip them out throughout the day or week.

Privacy first:

All your data stays in your browser. Nothing is sent to any external server. Your Substack session is used locally to post — we never see or store your credentials.
