• Platforms: Chrome and Firefox (Manifest V3)

What it does

• Flags when a response looks like a refusal, deflection, or filtered answer
• Shows the model’s current refusal rate inline
• Links each signal back to the methodology behind it
• Runs entirely client-side — your prompts are not sent to GPTfake
