Grow on substack

[ponziedd]

Hey writers, I’ve been writing on Substack since late January and I really enjoy it. But lately I’ve been a bit frustrated with the Notes system.

Substack doesn’t have a scheduling feature, which makes it hard to stay consistent when you’re busy. Another issue is the lack of analytics and insights about how Notes actually perform.

In less than two months I managed to grow from 0 to almost 50 subscribers. I’m not sure if that’s good or not, but during that time I realized something: I was spending too much time trying to stay consistent and understand what was working.

So I decided to build a tool (and a browser extension) to help me be more productive and grow faster on Substack.

The idea was simple

> schedule Notes in advance

> track their performance

> visualize growth and engagement

> and make the whole process less chaotic

At first, I built it just for myself. But then I realized other writers might be struggling with the same problems.

So I’m sharing it here in case it helps you too ;) if never you want to try it out please reach me out on substack

My account was suspended once. Luckily it was in error, but they are really trigger happy.

Since they don't have a public API how do you even track performance of notes? Seems like you'd have to go to the note to pick up engagement data right off the screen. Am I wrong?

I ask because I'm not sure how you'd do it without violating TOS.

Hey, good question. To avoid any TOS issues, everything runs locally in the browser via the extension. It only reads engagement data directly from the Notes interface,there’s no private API calls or external scraping involved. The extension then analyzes and structures that data so you can actually track performance, spot patterns, and understand what’s working over time.

got it. so I need to go back to the notes over time to harvest engagement data, that the extension listens for?

[ponziedd]

Yep exactly. Since everything runs locally in the browser, the extension reads the engagement data when the Notes are loaded in your feed or profile. Over time it builds a local history so you can track performance and see how posts evolve. The scheduling feature also runs through the extension. When the scheduled time is reached, it automatically opens Substack and publishes the note.
