How Our Professional AI Content Detection Tool Works
TextAdviser provides a high-precision AI content detector capable of identifying text created by modern generative systems. Our algorithm successfully recognizes content written by:
- Top global models: GPT-5, Claude, Gemini, and their Pro versions.
- specialized generators: Chinese models and a wide range of Open Source LLMs.
Whether you are checking a blog post or need an AI detector for essays, our system analyzes patterns invisible to the human eye.
Accuracy and Principles of this AI Writing Detector
When developing this AI writing detector, we were guided by the principle of the author's "presumption of innocence." Our main goal is to minimize false accusations against people writing on their own.
Testing Results: On a vast sample of examples, our system demonstrated an accuracy of 85%. Despite this high efficiency, we honestly warn about a small probability of error and are constantly working to reduce the percentage of false positives to remain the best AI content detector on the market.
Interactive Analysis: Understanding the AI Score
The system does not just issue a verdict; it visualizes the result. You can click on any text fragment to see the algorithm's confidence level for a specific sentence. The final assessment is formed from two indicators: the percentage of explicit generation and the percentage of suspicious text.
Color indication helps you instantly assess risks:
- ● Red — High probability of AI (strong influence on the score).
- ● Yellow — Suspicious text (moderate influence).
Detecting Mixed Content and "Hybrid" Writing
Authors often use a hybrid approach: they write the introduction and conclusion themselves but trust the main part to neural networks. Our AI generated text detector is capable of recognizing such "stitched" texts, highlighting generated insertions.
Tip: To get the most objective picture, we recommend using the AI Detector in conjunction with uniqueness check services (plagiarism checkers) to exclude both generation and direct copying from the Internet.

Frequently Asked Questions (FAQ)
Do I still need to check for uniqueness?
Yes, it is mandatory. The AI detector text tool determines only the artificial origin of the text but does not look for matches with already published materials. For a full analysis of content quality, please use the TextAdviser uniqueness check service alongside our AI content detection tool.
