PromptOpti's AI Detector is a free tool that identifies AI-generated, AI-refined, or human-written content.

Key Features:

  • Easy to use (no signup required).
  • Currently available at no cost.
  • No obvious character limit.
  • Development in progress for system integration (API).

Limitations and Considerations:

  • No clear data handling policy (use with caution for sensitive texts).
  • Relatively unknown tool: unknown future potential.

PromptOpti's AI Detector is best suited for personal content verification, as its reliability track record is not yet established for professional or institutional use.

Simply paste your text and click "Detect" to receive results. The system integrates with third-party tools like OpenAI, Claude, and Gemini.

While it is currently free to use, this might change in the future.
