AI Content Detector
Estimate the probability that a piece of text was written by AI, using readability heuristics.
Heuristic estimate (~70% accuracy), not proof. AI detectors are imperfect — use as a signal, never as a verdict.
Free AI content detector
AI writing tools have made it trivial to produce text at scale, and many people want a quick gut-check on whether a piece reads as machine-generated. This detector uses linguistic heuristics that run entirely in your browser: it measures burstiness (how much sentence length varies — humans vary more), the type/token ratio (vocabulary diversity), and punctuation patterns. From these signals it estimates a probability that the text was AI-generated.
Be honest with the result: no detector is reliable. They produce false positives on well-edited human writing and false negatives on AI text that's been lightly rewritten. Even commercial detectors hover well below certainty. Treat this as one data point — useful for spotting obviously templated, monotonous text, not for making accusations.
The better goal: content that doesn't read like a robot
Instead of dodging detectors, aim for writing that's genuinely good — varied sentences, real insight, a clear voice. That's what readers and search engines reward. aithor is built to produce content that reads naturally and serves search intent, so you're optimizing for humans, not for beating a detector.
FAQ
Are AI detectors accurate?
No detector is reliable. They give a probability, not proof, and produce both false positives and false negatives.
Will Google penalize AI content?
Google rewards helpful, high-quality content regardless of how it's produced — and penalizes spam. Quality is what matters.
