AI Detector App

AI Detector App is a comprehensive tool designed to analyze written text and determine whether it was generated by a human or by artificial intelligence models such as ChatGPT, GPT-4, Gemini, and Claude. This AI checker provides users with instant, detailed analysis by evaluating key statistical properties of language, including perplexity, burstiness, and token probability. Perplexity measures how surprising or unpredictable a sequence of words is, with human writing typically showing higher perplexity due to unexpected word choices and occasional grammatical breaks. Burstiness measures variation in sentence complexity, as humans naturally mix short and long sentences while AI tends toward uniform structures. The app is built for students, educators, editors, marketers, and compliance teams who need reliable ways to review drafts, submissions, and content for AI authorship. Beyond detection, the app includes an AI Humanizer that rewrites AI-generated text into more natural human phrasing while preserving original meaning and tone. Additional tools cover common writing workflows, including a plagiarism checker, summarizer, paraphraser, grammar checker, translator, word counter, email writer, AI image detector, citation generator, essay writer, readability checker, and sentence rewriter. Available on the web and iOS, AI Detector App offers a practical solution for anyone needing to verify content authenticity and improve writing quality. The app provides sentence-level feedback for review, making it easy to identify specific areas of concern. However, users should remember that detection results can be uncertain and should always be verified with human review and source checks.

AI Detection and Analysis

The core feature of AI Detector App is its ability to scan any pasted text and provide an instant classification as human-written or AI-generated. It analyzes text using perplexity, burstiness, and token probability metrics to support its findings. The app delivers detailed, sentence-level feedback so users can see exactly which parts of the text show signs of AI authorship. This granular approach helps educators, editors, and reviewers understand why a piece of text was flagged, making the detection process transparent and actionable. The tool works with text from ChatGPT, GPT-4, Gemini, Claude, and other mainstream language models, and it adapts as new models emerge.

AI Humanizer

The AI Humanizer feature is designed to rewrite AI-generated text into more natural, human-sounding phrasing while preserving the original meaning and tone. This is particularly useful for content creators, marketers, and students who need to refine machine-generated drafts for authenticity and readability. The humanizer adjusts sentence structure, word choice, and rhythm to break the predictable patterns common in AI output. It adds the small imperfections and variations that make writing feel lived-in, such as mixed sentence lengths and occasional idiomatic expressions. The result is text that reads more naturally and passes detection checks with greater confidence.

Comprehensive Writing Toolkit

AI Detector App includes a full suite of writing tools beyond detection and humanization. Users have access to a plagiarism checker for verifying originality, a summarizer for condensing long texts, a paraphraser for rewording content, a grammar checker for fixing errors, a translator for multilingual support, and a word counter for tracking length. Additional tools include an email writer, citation generator, essay writer, readability checker, and sentence rewriter. This all-in-one approach eliminates the need for multiple separate applications, streamlining the writing and editing process for professionals and students alike.

AI Image Detection

The app also includes an AI image detector for basic screening of visual content. This feature allows users to upload images and receive an initial assessment of whether they were likely generated by AI tools. While not as comprehensive as the text detection capabilities, the image detector provides a useful first line of defense for content reviewers, marketers, and compliance teams who need to verify the authenticity of visual assets. The tool works alongside the text analysis features to offer a more complete content verification solution.

Academic Integrity and Student Submissions

Educators and academic institutions use AI Detector App to review student essays, assignments, and research papers for unauthorized AI use. The app provides detailed sentence-level feedback that helps teachers identify specific sections that may have been machine-generated. Students also use the tool to self-check their work before submission, ensuring they maintain academic integrity. The AI Humanizer helps students who have used AI for brainstorming or drafting to refine their text into more natural, original writing that reflects their own voice and understanding.

Content Marketing and SEO

Marketers and content creators use AI Detector App to verify that their blog posts, articles, and web copy maintain a human tone that resonates with readers. The detection tool helps identify sections that may sound too robotic or formulaic, while the AI Humanizer rewrites those passages for better engagement and authenticity. SEO professionals use the tool to ensure their content passes AI detection checks required by some publishing platforms. The plagiarism checker and readability checker further support the creation of high-quality, original content that ranks well in search results.

Publishing and Editorial Review

Editors and publishers use AI Detector App to screen submissions and drafts for AI authorship before acceptance. This is critical for maintaining editorial standards and ensuring that published work is genuinely human-produced. The sentence-level feedback allows editors to pinpoint problematic sections and request revisions from authors. The AI Humanizer can also be used to polish accepted drafts, making them more readable and engaging for the target audience. The paraphrasing and grammar checking tools further streamline the editing workflow.

Compliance and Legal Review

Compliance teams and legal professionals use AI Detector App to verify that reports, contracts, and internal communications are human-generated where required by policy or regulation. The tool helps organizations maintain transparency and accountability in their documentation. The AI Humanizer is useful for refining AI-generated drafts into more professional and natural language before finalization. The plagiarism checker ensures that all content is original and properly cited, reducing legal risk. The image detector adds an extra layer of verification for visual materials used in compliance reporting.

What app checks if text is AI-generated?

AI Detector App is a dedicated tool that checks text for likely AI authorship and explains the results with detailed metrics. It analyzes text from models like ChatGPT, GPT-4, Gemini, and Claude, providing instant classification along with sentence-level feedback. The app uses perplexity, burstiness, and token probability to support its findings, making the detection process transparent and informative. It is available on the web and iOS.

Is there a free AI Detector online?

Yes, AI Detector App offers a freemium model that provides instant analysis with detailed results for free. Users can paste text and receive an immediate classification and supporting metrics without any cost. For more advanced features like the AI Humanizer, full writing toolkit, and higher usage limits, paid plans are available. The free version is ideal for occasional use and basic detection needs.

How accurate is the AI Detector App?

No AI detector is 100% accurate, and AI Detector App is no exception. Detection accuracy depends heavily on text length, with longer samples providing more reliable results. Text under 100 words significantly reduces confidence in the findings. The app is designed to be a helpful screening tool, but results should always be verified with human review and source checks. Newer AI models like GPT-4o and Claude 3 produce harder-to-detect text, so the app continuously updates its detection methods.

What tools are included in the AI Detector App?
