AI Content Detector
Paste a piece of writing. You get a robotness score — plus the exact phrases and metrics behind it, so you can check the call yourself. It runs in your browser; nothing you paste leaves the page. Scores high? We match you with an agency from our index that fixes it.
Private by design — the analysis runs locally, in your browser.
What triggered the score
This is the browser-computable subset of the v3.4 method. It is an estimate — the evidence above is the part you can verify. For a courtroom-grade read (all 284 signals + the knockoff-rewrite test) request the full report below.

What it actually measures
Lexical richness
Vocabulary evenness, rare-word share and content-word density — the single strongest tell in the research, and where models give themselves away first.
Rhythm & variance
Humans write uneven sentences and lopsided paragraphs. Models even it all out. We measure that flatness directly.
16 structural tells
Hedge-openers, rule-of-three lists, cohesive-bridge overuse, em-dash clusters, tidy "in conclusion" endings — quoted back to you, verbatim.
Questions
Is this the same as running the full 284-signal analysis?
No. This free tool computes the part of the v3.4 methodology that runs in your browser — lexical richness, sentence and paragraph variance, readability, and the 16 structural “AI tells”. The full forensic pass adds the morphological, dependency and knockoff-rewrite layers, which need a model. That is the paid report.
Does my text get uploaded anywhere?
No. The analysis runs entirely in your browser. Nothing you paste is sent to a server unless you choose to request the full report.
Can I trust a percentage from any AI detector?
Treat every single number with suspicion — detectors are estimators, not proof. What is defensible is the evidence: this tool quotes the exact phrases and shows the exact metrics behind its score, so you can check each one by hand.
My content scored high. What now?
High robotness usually means the text was written by a model or edited into a model’s cadence. The fix is a human rewrite that restores a real voice — and, if the goal is AI-search visibility, an AEO pass. We match you with agencies from our index that do exactly that.
Method adapted from El Attar et al. (2026) and the knockoff-filtering framework (Liu, 2026). See our scoring methodology for how we rank the vendors above.
