No.

StackSweller runs in the cloud, so you don't need a browser extension or to keep your computer on.

Just schedule your notes, close your laptop, and StackSweller will post them for you.

Create your StackSweller account. Link your Substack account. Pick your desired posting slots and then start scheduling your notes. That's it.

The viral note ideas feature is coming soon! For now, you can discover top performing notes through our analytics and create new spins out of them using AI. Our analytics show you which notes bring in more subscribers, helping you identify what resonates with your audience. You can then use AI to create variations and new content based on these successful patterns.

AI credits are used to give your old notes that performed well a new spin, and to turn long form content into more notes.

1 credit = 10 notes.

Slots = how many notes you can schedule at once, not per month.

Slots vary depends on the plan.

Got 20 slots? You can schedule 20 notes. When one publishes, that slot opens up and you can schedule another. You can publish unlimited notes per month—you just can't have more than 20 waiting in your queue at the same time.

Think of it like Buffer: you fill up your queue, posts go out, and as slots free up, you can add more.

You can publish unlimited notes per month.

Slots only limit how many notes you can have scheduled at once, not how many you can publish. As notes publish and slots free up, you can schedule more notes.

This means you can publish as many notes as you want—you're just limited by how many you can have waiting in your queue at the same time.

If you like batching a week's worth of notes in advance, we recommend going with the Growth or Premium plan.

Yes! While the StackSweller interface is in English, our AI can generate notes in your language. You can schedule and publish notes in any language you write in on Substack.
