Introduction to AI Detectors

Artificial Intelligence is rising day by day. It is becoming more powerful. It can replace an automated human task till some extent. It can generate content for human. It can summerize a large video in a brief sentence and what not. In this article, I will talk about top most accurate AI content detectors with detailed review, comparison, pros, cons and what are the pricing of these tools.

Detectors are important in various fields like education, journalism and content marketing. AI Detectors help identify whether the content is authentic and written by human or not. A content which is written by human is more meaningful, authentic, and ethical rather than a content written by AI.

What is an AI Detector?

An AI detector is a software program or application that identifies whether a content is generated by AI (Artificial Intelligence) or written by human. The content could be a paragraph, an article, a theory or a research paper.

It uses various techniques like pattern recognition, large language model, machine learning algorithms, probability scoring etc to differentiate between a human-written and AI generated text. It can be used to verify the authenticity of the content and avoid any penalties from search engines.

Top Most Accurate AI Detectors

There are several AI detectors on the market already and new detectors are released nearly every month. In that case it becomes more difficult for a person to find a best AI detector. I have made things easy for you. I carefully tested and investigated numerous AI detectors and created a thorough comparison list with features, advantages and downsides, and whether they are free or paid.

QuillBot

QuillBot AI detector is designed keeping content writers in mind. It uses its own custom developed algorithms to determine if the content is an AI-generated content or written by human. The tool detects and shows the portion of text generated by AI, human-written, AI-generated and AI-refined, and human-written and AI-refined. A refined text is one that has been written by human but corrected by AI.
