AI Content Detector
NewAnalyze any text to estimate the probability it was written by an AI. See which sentences are flagged and get suggestions to make your writing sound more natural and human.
⚠️ AI detection is inherently imperfect. This tool uses linguistic heuristics and achieves ~65–70% accuracy on pure AI text. Mixed human+AI text is much harder to classify. Use as a signal, not a verdict.
Frequently Asked Questions
How accurate is this AI detector?
This tool uses rule-based linguistic analysis and achieves roughly 65–70% accuracy on clearly AI-generated text. Mixed human+AI content is significantly harder to classify. No AI detector — including paid commercial tools — is reliably accurate. Use it as one signal among many.
What patterns indicate AI-generated text?
AI-generated text commonly contains: formal transition words (furthermore, moreover), hedging phrases (it is important to note), passive voice, very long sentences, lack of contractions, overuse of words like 'leverage', 'comprehensive', and 'delve into', and perfect punctuation.
Does my text get sent to a server?
No. All analysis runs entirely in your browser using JavaScript pattern matching. Nothing is sent to any server.
