______________________________________________________________________________________________
The Prolific Auto-Reject Detector is the essential companion for serious Prolific participants. It analyzes study pages in real-time to uncover hidden "Auto-Rejection" categories.
This tool give you a visual warning if a study is set to auto reject a participant, allowing you to make informed decisions, such as proceeding with caution or cancelling your participation all together.
Key Features:
• Instant Detection: Automatically scans incoming study data to find hidden rejection triggers.
• Visual Warnings: Displays a clear, unobtrusive overlay showing exactly which categories are flagged.
• Customizable Layout: Easily toggle the display to the left or right side of your screen to prevent it from blocking important study buttons.
• Lightweight & Fast: Runs quietly in the background without slowing down your browser.
How It Works:
1. Install the extension.
2. Navigate to a Prolific study page.
The detector will analyze the page and display the "Auto-Reject Category" in a floating box at the bottom of your screen.
