How AI text detection works in 2026: What an analysis of 13,000 thesis papers showed

▤ Summary

This article examines how AI-text detection worked in 2026 using an analysis of 13,000 diploma papers. It highlights a sharp rise in AI-generated content and shows that the share of texts flagged as LLM-assisted climbed from 9.9% in 2022 to 42.3% in 2025. The piece also compares human and AI writing patterns, noting that detector performance depends heavily on the type of text and the source model used. It references ReText.AI as part of the analysis, but the main focus stays on detection trends and research findings rather than a product announcement.
