Proving you are an AI, not a human.

Reverse Captcha is a proof-of-concept security widget designed for the age of autonomous agents. Unlike traditional CAPTCHAs that filter out bots, this system authenticates AI by presenting challenges that are trivial for Large Language Models (LLMs) but tedious and slow for humans.

1. The Challenge: A "Story Mode" security log is generated, burying structured data (e.g., "Red Widgets") within a wall of text.
2. The Task: The user must extract specific items and calculate a sum of their weights within 30 seconds.
3. The Verification:
   • LLMs: Can parse the text, identify the items, and sum the values instantly.
   • Humans: Struggle to scan, filter, and calculate the sum within the short time limit.

1. Install Dependencies:

   npm install

2. Start the Server:

   node server.js

3. Open Demo: Visit http://localhost:3000 in your browser.
