  Here's a rewrite that leads with what Substack writers actually want (growth, ideas, time saved) instead of features:

  **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.
  
  🔒PRIVACY FIRST
  
  - Everything stored locally in your browser
  - Optional anonymous usage analytics — easy opt-out
  - No account needed for the core features
  
  Pairs with stacksweller.com when you want deeper insights and to connect your own Substack account.
