What if you could block an AI prompt before it ever reaches the LLM? In this Nulgen AI review, we look at a browser extension and website tool designed to act as a pre-processor for AI prompts.
Nulgen runs directly on your device, requires no account and blocks prompts before they are entered into the AI model. That creates a different approach to AI safety compared with filtering the output after it has already been generated.
The video explores potential use cases for parents, educators, schools, colleges and universities, as well as IT and security teams looking for centralised management.
We also take a quick look at the browser extension and Nulgen's pricing. If you're interested in AI safety, prompt filtering, LLM security or controlling AI access, this review shows how Nulgen approaches the problem.
