An update to my reading app is out that adds Shortcuts actions to automate and integrate with other apps. You can filter/sort based on many properties, including word count. There are also new lists for “Short Articles” and “Long Articles”.

Screenshot of Shortcuts app. Left side of screen shows a shortcut with these actions: Find All Articles where All of the following are true: Author is Douglas Hill and Date Saved is in the last 1 month and Title contains JavaScript. Sort by: Word Count. Order: Biggest First. Limit: Off. Choose from Articles. Open Chosen Item. Right side of screen shows all available actions for the Reading app: Add Articles, Delete Articles, Find Articles, Get Body of Article, and Open Article.
