NextGen-CAPTCHAs is a tool designed to protect websites from automated programs that use advanced AI, like large language models, to interact with web forms. By generating special CAPTCHA challenges, this software helps stop these smart bots from abusing online services.
This project includes two main parts:
- A system that creates new types of CAPTCHAs based on images and logic puzzles.
- Tools that test how well your site resists these advanced bots.
You do not need any technical knowledge to use this software to make your website safer.
If you manage a website or an online service where security matters, NextGen-CAPTCHAs can help. It works well for:
- Website owners worried about spam or unauthorized access.
- Administrators who want to prevent AI bots from filling out forms automatically.
- Anyone needing simple, effective CAPTCHA protection without complex setup.
