| Status | Discontinued July 2023 | Active, expanding benchmarks in 2026 |
| Core Function | AI-generated text detection | Expert human feedback for RLHF & red teaming |
| Accuracy | 26% true positive, 9% false positive | Expert-graded evaluations (see Antidote) |
| Best For | Educators & researchers exploring detection | Frontier AI labs requiring domain experts |
| Latest News | No replacement; OpenAI focuses on other tools | New benchmarks (Riemann-bench, GDP.pdf, Antidote) in June 2026 |
AI Text Classifier is a discontinued, low-accuracy free tool unsuitable for production. Surge AI is an active, expert-driven platform for frontier AI alignment with rigorous benchmarks and a proven track record (e.g., Microsoft's MAI-Thinking-1). For any serious AI safety or RLHF work in 2026, Surge AI is the clear choice.
Retired AI text detector from OpenAI, discontinued July 2023 due to low accuracy.

What users praise
- • Expert human workforce (doctors, lawyers, engineers) ensures high-quality evaluations.
- • Benchmarks cited by OpenAI and Anthropic for credibility.
- • Specializes in RLHF and red teaming for frontier AI alignment.
- • Custom RL environments, including MCP-native, for enterprise tasks.
What frustrates them
