slap.

The reality check you didn't ask for.

slap. is a minimalist, pastel-aesthetic web application that uses Google's Gemini 3 API to analyze your complaints and return a brutally honest assessment of your cognitive biases.

Features

• Brutally Honest AI: Analyzes user input for cognitive biases (e.g., emotional reasoning, catastrophizing) using a "clinical and unsympathetic" persona.
• The Three-Part Slap:
  1. Reality Check: A harsh call-out of your bias.
  2. Philosophical Slap: A quote from realist philosophers like Nietzsche or Cioran.
  3. Prescription: A book recommendation to fix your mindset.
• Minimalist Aesthetic: Clean, pastel design with sharp typography.
• Security & Safety:
