Shown·Claude Cowork, Claude in Chrome·Newsletters
Weekly Substack ranking report
Claude in Chrome scrapes the top 250 Substack newsletters from Reletter each week, then Claude Cowork turns the data into a gains and losses report.
The author's weekly chart scraping and rank analysis now runs as two scheduled tasks every Tuesday, replacing manual copy-paste and taking a couple of minutes.
Overview
How it was set up
Claude in Chrome runs the scrape, launched from Claude Cowork. Both use scheduled tasks created by converting a working prompt, set for Tuesday at 5 PM and 5:10 PM.
Worth knowing
Tasks only run while the computer is awake and Claude Desktop is open. Each run uses the daily usage allowance.
A prompt to start from
Based on the data in the folder [folder name], analyze the rankings: top 10 biggest rank gains, top 20 new entrants, top 10 biggest rank losses. Do this separately for [dataset A] and [dataset B].
