Welcome to Excellent AI Prompts
You do not need more hustle. You need a system that compounds inside Substack. Today you get the map and the prompts to run it.
If you're a writer or creator, you've been sold a story of relentless hustle. Post more, shout louder, and be everywhere at once.
What if the key to growth isn't more effort, but a better system?
What if you could stop shouting into the off-platform void and start compounding your work inside the very network designed to help you grow?
That’s what we’re building today.
Forget random acts of content.
We're architecting a repeatable, AI-assisted growth engine specifically for the Substack ecosystem.
The Situation
Growth on Substack is an on-platform game.
The company has been explicit about this, noting that discovery features like their recommendation network, are driving a massive share of new subscribers. In a recent update, they noted, "[we're] making it seamless for a reader of one publication to discover and subscribe to others." And they have.
This network effect is powered by features like Notes, which Substack confirms distributes your short-form content far beyond your existing followers, that creates a new channel for audience acquisition that delivers long after the initial post, unlike social platforms.
The Problem
Most creators are leaving all this growth on the table. They treat the platform like a simple blog, posting content without a strategy that leverages the network.
The mistakes are costly: choosing vague topics that don't align with reader interests, recommending other publications randomly instead of strategically, and turning on paid subscriptions with no clear offer or logical moments to upgrade. These actions don’t just fail to help, they actively work against the advantages Substack is trying to give you.
The AI Solution
We will use AI not as a ghostwriter, but as a growth operations partner. The goal is to treat your Substack growth like a product, with a clear system and repeatable workflows.
We'll use prompts to build a topic graph that maps directly to the network's interests, to craft Notes designed for discovery, to find and curate the perfect recommendation partners, and to design a monetization strategy that feels natural to your readers. The AI provides the structure and speed; you provide the insight.
