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 with the Pro plan.

Schedule as many notes as you want and post as many times as you like—there are no limits.

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.

We built Stacksweller with your account security as a priority. The tool only does what you could do manually—it just saves you time by scheduling your posts.

That said, anytime you use a third-party tool to a platform, there's some level of risk. Substack can change their rules. We can't control that.

What we can control: we don't do anything shady or automated that Substack prohibits and follow best practices.

Due to Substack limitations, you'll need one StackSweller account per Substack account.
