Smart Chrome extension that analyzes your prompts before sending and explains why AI blocks certain content. Works seamlessly with ChatGPT and Claude.
The word "explosive" triggered the violence filter. Here are safer alternatives:
AI chatbots block legitimate requests without explanation, leaving you frustrated and unproductive.
"I can't help with that" - No explanation why your legitimate request was rejected.

Give up and lose the benefits AI was supposed to provide.
