This website counts titles containing the standalone word "AI", case-sensitive and
word-bounded. "OpenAI" doesn't count. "AI-powered" does. There's a toggle for a
wider vocabulary: artificial intelligence spelled out, LLM, GPT, and model and
vendor names.
Some quick stats:
- 14.4% of new HN titles this year, against 10.9% in 2025. On the wider vocabulary, 21.9% and 16.1%. - First month above 1% was Oct 2016. Above 5%, Feb 2023. Above 10%, May 2025. - Over the last five years the quietest month was Jan 2022 at 0.8%. The peak was Feb 2026 at 15.9%. - 13.6% on weekdays against 12.4% at weekends. - Show HN runs highest of any category at 19.8% this year, which makes this post part of the number.
As of this post, today is at 15% for the standard filter and 19% for the extended.

Thanks for the cool project!
lcamtuf's survey (linked in the footer) was looking at the front page, and the number there was quite a bit higher. So there's likely some effect from voting, although I haven't dug into that yet.
I think Algolia has a way to filter for front-page stories, which should make it pretty easy to add. I haven't tested that yet though but will certainly look into it!
But then the authors lie or make ludicrous excuses for why their article "sounds" like AI. Then I check with Pangram and yep. It is completely AI written.
You get a few free checks on Pangram each day or so. Just start checking and encourage people to be honest.
AI has its place. Lying about it and misrepresenting it makes everyone dislike AI more, even as they use it themselves.
“AI detectors” do NOT work reliably.
Even humans who are ever-so-certain about being able to identify AI usage constantly embarrass themselves when that claimed ability is put to the test. Look up “AI Monet Instagram” for a social experiment where hundreds of cocksure users pointed out “AI signs” in what was claimed to be an AI-generated painting in the style of Monet, but was actually a genuine Monet.
If you see:
- ALL CAPS subheaders
- a light beige background
- burnt sienna anchor and/or highlight text
- a "• LIVE" (or really any pulsing • symbol with an ALL CAPS follow-up)
- tons of variation in font sizes (this one has 15 different text sizes!)
- more typically, a lot of overexplaining
...you know it's vibe'd, specifically with Claude!
It is also interesting to note that I have already received 5 AI written emails to the email I linked in the footer.

I think I misunderstood - how many posts were about AI vs how many posts were written by AI.
I obviously am suffering from berry fog.
