Scheduler Guide
Schedule Substack Notes for future posting using the Quick Viral Notes browser extension.
Install the extension
Download the Quick Viral Notes Chrome extension from the Chrome Web Store. After installing, click the extension icon and sign in with your QVN credentials.
Connect your Substack account
Navigate to substack.com and make sure you're logged in. The extension reads your Substack session automatically — no additional setup needed.
Schedule a note
From the QVN app, click 'Schedule' on any generated note. Choose a date and time. The note appears in the extension's queue. The extension background worker checks the queue every minute and posts at the scheduled time.
View scheduled notes
Click the extension icon to see all upcoming scheduled notes. You can edit the content, change the time, or cancel from here. Changes sync instantly to the server.
Timing rules
QVN enforces a 2-hour minimum gap between notes on the same day to avoid Substack rate limits. The scheduler also randomizes posting minutes (not :00 or :30) for a more natural posting pattern.
Troubleshooting
If a note fails to post, the extension marks it as 'failed' and notifies you via email. Common causes: logged out of Substack (re-authenticate by visiting substack.com), or the scheduled time passed while your computer was off.
