If you’re a creator deciding between ConvertKit and Substack, you’re not alone.
Both platforms help creators build an audience — but they are designed for very different goals.
In this guide, I’ll break down Kit (Formerly ConvertKit) vs Substack clearly, without hype, so you can choose the tool that actually fits how you want to grow and monetize.
Quick Verdict
ConvertKit is better if you want:
- Full ownership of your audience
- Automation and funnels
- Multiple monetization options
Substack is better if you want:
- A simple newsletter
- Built-in discovery
- Paid subscriptions with minimal setup
If you plan to grow beyond “just a newsletter,” ConvertKit is usually the better long-term choice.

What Is Substack?
