About AI Impostor

AI Impostor is a simple game where you're shown a real Reddit post followed by four replies — three written by humans and one generated by AI. Your goal is to spot the AI.

The AI comments are generated by multiple models, including ChatGPT, Gemini, and Claude. More models will be added over time.

Beyond being a fun guessing game, AI Impostor is also a research project. Every guess is stored (anonymously) to help answer questions like:

• Can humans reliably detect AI-generated comments?
• Which AI models are most convincing in mimicking human language?
• What kinds of topics or tones are hardest for AI to replicate?

No login is required, and no personal information is collected. Just play, guess, and help us learn more about AI and human perception.
