Show HN: How much of Hacker News is AI?

The site counts Hacker News titles containing the standalone word “AI” (case-sensitive, word-bounded), excludes “OpenAI”, and includes “AI-powered”. An extended filter adds “artificial intelligence”, LLM, GPT, and vendor names. In 2026, 14.4% of new titles matched the basic filter (21.9% with the extended list), up from 10.9% (16.1% extended) in 2025. The peak monthly rate was 15.9% in February 2026; the trough was 0.8% in January 2022. Weekday titles show 13.6% AI presence versus 12.4% on weekends, and Show HN posts account for 19.8% of AI-related titles this year.
