Is my content detectable as AI-written?
Is my content detectable as AI-written?
If it reads like a machine wrote it, the answer is yes. That answer now carries a compliance cost under the EU AI Act.
Why AI-written content is a live question now
The EU AI Act's transparency rules took effect on 2 August 2026 and require disclosure wherever AI-generated content is published. Content already on the market has to be marked by 2 December 2026. Buyers and clients are getting better at spotting machine text, and so are other AI systems. Undetected machine-generated copy now sits on a compliance question and a trust question at the same time.
The signals that make content read as AI
Detectors key on a few patterns, and human readers key on the same ones.
- Sentence rhythm that never varies, under a structure that never varies.
- Filler phrases that carry no information, such as "in today's fast-paced world."
- Symmetry that is too tidy: every paragraph the same length, every list the same shape.
- Confident, generic statements with no specifics, no numbers, no named examples.
None of these alone proves anything. Together they form the pattern.
The caveat about detectors
No detector is reliable enough to trust on a single sentence, and the tools disagree with each other on the same passage. The useful question is whether this page reads as machine-generated to the person you want to trust you. A machine can support that judgement. A person has to make it.
How to find out for your own site
Run your own pages through an audit that checks for these signals and names the parts to rewrite. Our AI-Tell Audit assesses how likely each page is to read as AI-generated and reports the signals it found. You fix what the report names.
