This guide provides a detailed look into the best AI content detectors on the market, focusing purely on detecting AI-generated content. Whether you're a teacher, a content manager, or simply want to verify that content is human-generated, these tools will help you identify AI-produced material effectively. After thoroughly testing multiple detectors, we’ve shortlisted the top options based on usability, accuracy, extra features, and affordability. Here's what makes these detectors stand out.

TraceGPT

What It Does: TraceGPT is a part of PlagiarismCheck.org and focuses primarily on detecting AI-generated content with near-perfect accuracy. The tool also includes additional features like a plagiarism checker and authorship verification, making it an excellent choice for those concerned with content originality and integrity.

Technology Recency: TraceGPT is a relatively new player in the AI detection space, but its quick adoption and accuracy make it a strong competitor.

How Well It Works: In tests, TraceGPT was nearly flawless in detecting both GPT-based and Claude-based AI content. It accurately flagged AI content and confidently identified mixed pieces as well. For instance, it correctly labeled a mixed piece of human and AI-generated text as 46% AI-generated, highlighting specific sentences for clarity.

Cost: Prices start at $5.99 for 20 pages of AI detection. This includes 275 words per page. For plagiarism detection, additional subscriptions may be required, but custom offers can be negotiated for AI-only usage.

Best For: Educators, content managers, or business professionals needing detailed and confident AI detection results, especially in longer-form content.

Winston AI

It can detect GPT-4, Google Gemini, and Claude AI content and includes plagiarism checks, readability scores, and OCR capabilities for scanning documents, pictures, and even handwriting.

Technology Recency: Winston AI has been evolving quickly, integrating new language models as they emerge, including GPT-4 and Claude.

How Well It Works: Winston AI performed well, though it incorrectly identified Claude-generated content as human. Despite this, it correctly labeled the majority of AI-generated texts and highlighted mixed content with decent accuracy. A key advantage is its ability to handle different types of documents, like scanned images and PDFs.

Cost: Prices start at $12/month for 80,000 words or $19/month for 200,000 words. They offer a 7-day free trial with 2,000 words.

Best For: Educators, content managers, and businesses needing to integrate AI detection into multiple platforms like Google Classroom, Blackboard, or through APIs.

Technology Recency: GPTZero has been updated to work with multiple AI models, though it struggled with Claude-based content.

How Well It Works: GPTZero's results were mixed. While it performed well with GPT-generated content, it was confused by mixed and Claude content. However, the tool provides detailed analyses using perplexity and burstiness, which offer additional context for interpreting results.

Cost: The basic free plan allows up to 10,000 words per month, with premium plans starting at $10/month for 150,000 words.
