How This AI Prompt Cleaner Works

This prompt engineering tool analyzes your AI prompts and provides actionable improvements. When Chrome AI is available, it uses the Rewriter API to directly improve clarity and specificity. In all other browsers, it runs a comprehensive rule-based analysis covering vague words, structure, readability, and prompt type detection.

Better prompts lead to better AI outputs. This tool helps you write prompts that are clear, specific, well-structured, and optimized for whatever AI model you are using.

Anatomy of a Great Prompt

  • Role/Persona — Tell the AI who to be ("You are an expert...")
  • Clear Instruction — Specific action verb ("Write", "Analyze", "Compare")
  • Context — Background information the AI needs
  • Output Format — How you want the response ("as a table", "in bullet points")
  • Constraints — Length, tone, style, what to avoid
  • Examples — Show the AI what good output looks like

Privacy-First AI

Your prompts may contain proprietary strategies, business ideas, or sensitive context. This tool guarantees privacy — Chrome's Gemini Nano runs on your hardware, and the analysis engine processes everything in your browser's JavaScript engine. Nothing is ever transmitted.
