Real writing by real humans.

NAC — No AI Content. A badge for blogs written by a person, not generated end-to-end by a machine. Add it to your sidebar to tell readers the ideas and words are yours.

I miss the old web — blogs where a human actually thought and wrote. Using AI to sharpen a sentence or pressure-test an idea is fine. Publishing a soulless, end-to-end AI-generated post as your own is not. This badge is a small, honest signal that a person is still behind the words.

Questions

Is NAC anti-AI?

No — it's pro-human. Using AI to fix grammar, tighten a sentence, or pressure-test an idea is fine. What NAC stands against is publishing whole posts generated end-to-end by a machine and passing them off as your own writing.

Do you track my visitors?

No. NAC records only the domain the badge runs on, plus a timestamp and a count. No IP addresses, no cookies, no visitor profiles.

Can NAC prove my content is AI-free?

Honestly, no tool can — AI detectors routinely mislabel real human writing. The badge is a declaration you choose to make. The optional Check page gives constructive feedback to help you improve, not a verdict.

Is it really free?

Yes. NAC is free and open source (MIT). Host it yourself or use the shared instance — no account required to add the badge.

Where can I put the badge?

Anywhere you can paste HTML — a sidebar widget, a footer, an about page, or a byline. It works on WordPress, Ghost, Webflow, Framer, and plain HTML sites.
