Ellia Lebleu, a founding member of the WikiProject AI Cleanup, says volunteers launched the effort in 2023 after noticing AI-written articles; by 2025 AI text patterns had grown subtler and volunteers are combining human review with detection tools and source-verification AIs to remove problematic machine-generated content.

Lebleu says she worked with detection firm Pangram, which flagged about 20 percent of new articles and drafts as AI-generated in late 2025 and about 15 to 16 percent in early 2026; she characterizes those figures as a conservative lower bound.
