Analyze text to estimate AI-generation probability using statistical linguistic features. Pure client-side — your text never leaves your device.
This tool uses statistical linguistic analysis (not AI models) to detect patterns common in AI-generated text. Sonuçlar are estimates, not definitive proof.
AI Content Detector is a free, privacy-first tool that analyzes text using statistical linguistic features to estimate the probability that it was generated by an AI model. Unlike cloud-based detection services, all analysis happens entirely in your browser — your text is never sent to any server, stored in a database, or shared with third parties. The tool examines sentence length variation, lexical diversity, AI connective word usage, and repetitive patterns to provide an informed estimate. While no statistical method can guarantee 100% accuracy, this tool gives you a data-driven starting point for evaluating text authenticity.
This tool uses statistical linguistic analysis rather than machine learning models. It examines patterns like sentence length uniformity, vocabulary diversity, and common AI transition phrases. While it provides a useful estimate, no statistical method can guarantee 100% accuracy. Human writers may occasionally score as AI-like, and sophisticated AI text may score as human. Use the results as one data point among many.
Yes, absolutely. All analysis happens entirely within your browser using JavaScript. Your text is never uploaded to any server, stored in a database, logged, or shared with any third party. This ensures complete privacy and security, even for sensitive or confidential content. You can verify this by checking that no network requests are made when you click "Analyze Text."
The tool analyzes four key linguistic metrics: (1) Sentence Length Variation — measures whether sentences are uniform in length (common in AI text); (2) Lexical Diversity — calculates the ratio of unique words to total words; (3) AI Connective Words — counts transitional phrases like "furthermore," "moreover," and "additionally" that AI models overuse; (4) Repetitive Patterns — detects structural similarities and repeated phrases across the text.
Statistical linguistic analysis requires a sufficient sample size to produce meaningful results. With fewer than 30 words, metrics like lexical diversity and sentence variation become unreliable due to insufficient data. The tool will display a warning if your text is too short and encourages you to provide more content for accurate analysis.
No tool can detect all AI-generated text with perfect accuracy. This detector focuses on statistical patterns common in AI writing, but advanced AI models are constantly improving and may produce text that appears human-like. Additionally, some human writers naturally use formal, structured language that may trigger AI-like scores. The tool is best used as one indicator among several.
These categories are based on the combined statistical score: "Likely Human-Written" (low AI probability) indicates natural variation in sentence structure, rich vocabulary, and minimal AI connectives. "Possibly AI-Assisted" (medium probability) suggests some AI-like patterns but with enough human variation to be uncertain. "Likely AI-Generated" (high probability) shows strong statistical indicators of AI authorship including uniform sentences, repetitive patterns, and excessive connective words.
No, this tool does not use AI or machine learning models. It relies purely on statistical linguistic analysis — counting and measuring patterns in the text itself. This approach has advantages: it works offline, requires no API keys, processes text instantly, and preserves complete privacy since no data is sent to external servers.
Yes, this tool is completely free to use for both personal and commercial purposes. There are no usage limits, no registration requirements, and no watermarks. You can analyze as much text as you need for content verification, quality assurance, research, or any other legitimate purpose.
