Summarizer.org's free AI detector highlights AI vs human content and shows detection scores, with a 3,000-word limit.
DetectorTools.ai is the largest directory dedicated to AI detectors. It is free to use and will help you find the latest and greatest AI detectors for personal, professional, or academic use.
DetectorTools.ai groups AI detectors into four categories: Free (no cost, unrestricted), Free Trial (full access for a limited time), Freemium (free with limited features), and Paid (requires payment for access).
Not all AI detectors are created equal. Some work excellently while others might struggle with certain use cases. That's why we have an accuracy rating for each tool that we list, so you can make an informed decision on which tool to use. Disclaimer: Results may vary. Always do your own testing.
We distinguish three user categories: Personal (for individual use, small-scale projects, and students), Professional (for team-based solutions, covering both small businesses and large enterprises), and Academic (for educators and advanced students requiring top-tier tools).
DetectorTools.ai is updated weekly. New tools are added as they enter the market or are submitted to us. To stay most up-to-date with our directory, subscribe to our newsletter or follow us on X.
We test all the tools following a set testing protocol. If you have any questions or suggestions, write to us at info@detectortools.ai or message us on X.
