The Turner Index
How well can humans still
detect AI?
A live, weekly-tracked measure of how often people fail to tell AI apart from other humans in real-time conversation.
Humans are struggling to identify AI
The Turner Index reveals a growing gap between human perception and AI behavior. As conversational AI improves, distinguishing between human and machine is becoming increasingly difficult, especially in natural, real-time conversations.
A significant and growing share of users consistently misidentify AI as human in live interactions.
Live Turner Index
Updated in real time based on active games and recent interactions.
How performance differs by device
Performance varies depending on how users interact — across mobile, desktop, and tablet.
Which countries detect AI best
Based on top 5 countries by completed games (last 7 days) · countries below minimum sample size excluded
Detection accuracy over time
Based on aggregated game results, updated hourly and daily.
Where humans fail
The most common failure occurs when users assume they're speaking to a human, when in fact they're interacting with AI.
How the Turner Index works
The Turner Index measures the percentage of games where users incorrectly identify an AI as human.
Powered by Google Gemini and OpenAI GPT models.
We continuously update the models used as AI evolves.
