Free AI Detector

Not as accurate as anyone selling one would like you to think. Every detector — ours included — is probabilistic, and false positives are common, especially on short, edited, or non-native English text. Treat any score as one data point, never as proof. That's why we show a probability and a prominent disclaimer rather than a confident yes/no.

No. Google doesn't penalize content for being AI-assisted — it penalizes unhelpful, low-quality content regardless of how it was made. Helpful, accurate, well-written content ranks; thin filler doesn't. That's the whole reason we focus on quality, not on 'fooling' a detector.

That's the entire point. Structura writes in your brand voice with varied sentence rhythm and concrete specifics — the things that make content read like a person wrote it (and that make it genuinely better, not just harder to detect). Quality first; passing a detector is a side effect.

Yes. It runs entirely in your browser — your text is never uploaded, stored, or shared. There's no signup, no limit, and no cost. We built it as a free, honest tool, not a lead trap.
