Deep Insights

Our deep insights pipeline is State-of-the-art in AI Detection and Model Interpretability. This is particularly important for educators and content writers to pinpoint areas of text that are highly plagiarized by AI.

: With deep insights, you know precisely which sentences in the whole text are AI, Mixed, or written by a Human.
: Phrase-level insights let you explore even further, highlighting which parts of a sentence are likely contributing to a higher AI score.
: The above combined provides a granular view of detection results with color-coded highlights. The impact score list lets you easily scroll through the top AI, or Mixed sentences.

Results

Our models can detect text written by any closed or open-source AI model, including GPT-4, Chat-GPT, Claude AI, Gemini, Microsoft Copilot, LLaMa, Grok, and Mistral. isgen boasts an accuracy of 96.4% on a benchmark where the most used AI Detector tool in the market has an accuracy of 81.22%. Our AI Detection tool provides a false positive ratio of nearly 0%, so you can safely rely on the model results and don’t worry about your written content being wrongly labeled as AI. Our multilingual AI Content Detector beats every other detector out there by a huge margin. Our study revealed that the most multilingual AI Detectors in the market are so inadequate and inconsistent that we couldn’t even compare the results directly, as a random model would have performed better than those detectors.

Frequently asked questions

: Isgen is a multilingual-first artificial intelligence company dedicated to promoting transparency by enabling everyone to validate AI-generated content. We provide detailed insights for students, writers, and content developers, highlighting to the word level why a particular piece could be perceived as AI-written, which enables them to evaluate their text, thus ensuring human authorship. As a company, isgen.ai is committed to providing equal access to all, offering the most accurate multi-lingual AI detection solution available in the market today.
: You can assess AI-generated content using our AI Content Detector tool. To do this, simply paste the text directly into the input box, upload a file, or provide a URL to a web page you wish to scan for AI plagiarism. The tool will automatically detect multi-lingual content and use the relevant model for processing.
: Indeed, you may check for AI-generated content using the free AI detector provided by Isgen.ai. This enables you to test out our potent detecting capabilities for free.
: While AI detectors are not 100% accurate, Isgen is the best AI detector in the market that works for all languages. The detailed analysis tool provides insights into why a certain piece of text was marked as AI or can be considered as likely Machine Generated, which can help students, writers, and content developers future-proof their writing against any AI Text Detector.
: Absolutely; LLMs or Large Language Models, such as Chat-GPT, tend to write in a certain manner that can be easily distinguished from text written by humans. These models write text with low perplexity and burstiness, always following the same pattern and using the same strategy to present ideas. Consequently, these characteristics make their output easier to identify.
: Our AI-generated text detector uses advanced machine learning algorithms and models trained on millions of samples. To arrive at a conclusion, the software looks at the structure of sentences, word choices, and patterns. It then assigns a probability to each phrase in the input with a confidence level that it was generated by an AI or written by a Human.
: Isgen employs highly complex algorithms and matches the input text with millions of samples. Our AI writing detector has seen outputs from every Large Language Model, i.e., Mistral, Llama, Claude, Gemini/Bard, GPT-3.5, and GPT-4. In addition, we continuously update our algorithm with data from newer models.
: Yes, Isgen's algorithm is developed in such a way that it looks at the input text as a whole, as well as paragraph by paragraph, sentence by sentence and even at the word level. To make a system that has the lowest false positives, we have employed multiple techniques that look at the text from different perspectives, both semantically and syntactically. Thus, any mix of AI and Human text can be easily detected.
: AI Detectors, including Isgen, are not 100% accurate. There is a possibility of false positives. We have trained our models on millions of pieces of educational content; thus, the possibility of misclassification is very low. However, if a false positive occurs, you can do the following:

Use our Deep and Detailed Insights tool to get an idea of which parts of the text were detected as AI with the highest impact score. It is likely that only those parts of the text are pushing up the AI Score.
To assess the student's understanding of their writing, allow them to justify why the piece was not generated by AI. This justification could be in the form of an in-person assessment, a proof of how they came up with the ideas for the writing, or how they compiled the whole piece together. It could also be shown through the version history of the editor they were using.
There's a possibility that they used AI to develop some ideas or create the first draft. Our models not only detect the written text (syntactically) but also understand how an AI model would structure a certain topic. In such cases, even though the content is largely written by the student and structured according to the AI model's suggestion, it could still be flagged as AI. For such false positives, allow the student to justify their use of AI and if it is within the bounds of the rules permitted by the institution.
: No, we do not store any data. Input history is maintained for users with a paid plan, but it can be deleted at any time.

Why Use an AI Detector?

The authenticity and uniqueness of published works are guaranteed by an AI detecting tool. Generative AI and Machine Learning make it simple to fabricate text, which can result in plagiarism and harm the author’s reputation in the workplace and school. An open AI detector, such as Isgen, finds originality by examining text to see if it was written by a human or an AI. The software offers advice on how to make text better, which is beneficial to writers and other content producers.
