Substack Notes Scraper
Substack has no public API for Notes analytics. You can't see likes, comments, and restacks in one place without scrolling through your feed manually. This skill scrapes the rendered Notes page, filters to only your original content, and exports everything to a spreadsheet you can actually analyze.
