Text Detection Rankings
AI-generated text identification across GPT, Claude, Gemini, and other large language models. Evaluates accuracy, false positive rates, and model coverage.
Text detection platforms identify whether prose was written by a large language model (GPT, Claude, Gemini, Llama, Mistral, and their derivatives) or by a human author. The 2026 Global 100 evaluated 6 text detection platforms against a 10,000-document reference corpus spanning unmodified AI output, paraphrased AI output, hybrid human-AI documents, and pure human writing across academic, journalistic, technical, and creative registers.
Three metrics drive the category: balanced accuracy (correct classifications across class distribution), false positive rate (human writing wrongly flagged), and model coverage (breadth of generation systems detected). The platforms ranked below combine those three with eight additional KPIs including transparency, API quality, update frequency, and cross-language support.
The category leader, Proofademic, scored 95.9. Six additional platforms scored above 90 overall. The category saw the most new entrants in 2026 and the narrowest score distribution among the top 10.
