**StackSweller — Grow Your Substack Faster by Seeing What Actually Works**

Stop guessing what to write. StackSweller adds a side panel inside Substack that shows you what's working on any profile — so you can spot winning notes, model top creators, and save the ideas worth revisiting.

WHY WRITERS USE IT

Substack hides the data you need most.

You can see that a note went viral, but not which notes consistently perform for other creators in your niche.

StackSweller pulls back the curtain on any profile in one click — yours, your competitors', or the creators you want to learn from.

✅ HOW IT WORKS

Click the StackSweller icon on any Substack page. A side panel slides in with the data Substack doesn't show you on the page.

🕵️ SEE WHAT'S WORKING ON ANY PROFILE:

- The top 5 notes ranked by likes — see exactly which hooks, formats, and topics land
- The top 5 posts ranked by engagement — reverse-engineer what your audience (or someone else's) actually reads
- Total notes and posts published — gauge how much output it took to get there
- Works on @username profiles, publications, custom domains, and the main feed

💾 SAVE THE NOTES WORTH STUDYING

Scrolling Substack and seeing a note you want to come back to?

One click bookmarks it.

Your Saved tab keeps the full list, and you can export it to CSV anytime — perfect for building a swipe file of hooks and ideas.

👉 TAKE YOUR RESEARCH ANYWHERE

Export notes and posts (with engagement numbers) to CSV or JSON. Use it to plan your editorial calendar, study a niche before entering it, or track how your own profile is growing over time.
