Explore these plagiarism checkers to find out if the text you're viewing is original, copied in any way, or AI-paraphrased.
Discover our comprehensive list of all AI detectors.
Plagiarism checkers can be useful for various users for personal and professional use:
For Students:
Before you submit your assignment that you've worked so hard on, check out the tools under the personal section to carry out a self-check and ensure that everything is correct, avoiding any unpleasant surprises.
For Educators:
Use plagiarism checkers to make sure students turn in their own work and follow the rules about giving credit to original sources. Ensure that all students are graded fairly based on their own efforts. Check out the tools under the professional use filter.
For Writers:
Use plagiarism checkers to ensure that your work is original and properly attributes any borrowed content. Check out the tools under the personal and professional use filters.
As AI writing tools develop, plagiarism checkers need to keep up with heavily modified (AI-paraphrased) text. Currently, well-known academic tools perform very well in these scenarios. However, more accessible non-professional tools can struggle with modified text. So always use caution and keep your use case in mind.
In the future, AI could detect student cheating by comparing their usual writing style—vocabulary, sentence structure, and patterns—to their submitted essays. If an essay deviates from a student's typical linguistic habits, it may indicate it was authored by someone else, suggesting it might be bought from a writing service. This technology would enable teachers to spot non-original student work.
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 individual, 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).
Our directory helps you find tools that have API support. This is helpful if you want to use the tool on a big scale, like on your website or other places. APIs let different software talk to each other, making it easier to use these tools in more advanced ways.
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.
