Beyond detection, the app includes a powerful AI Humanizer that rewrites AI text into more natural, human-sounding phrasing while preserving the original meaning and tone. It also offers a full suite of writing tools 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 is built for anyone who needs to navigate the growing world of AI-generated content with confidence and clarity.

AI Detection with Detailed Metrics

This feature analyzes your text and provides a clear estimate of whether it was written by a human or generated by AI models such as ChatGPT, GPT-4, Gemini, and Claude. It does not just give a simple percentage. Instead, it breaks down the analysis using three key metrics: perplexity, burstiness, and token probability. Perplexity measures how surprising or unpredictable the word choices are, with human writing typically showing higher perplexity due to natural variations. Burstiness looks at the variation in sentence length and complexity, as humans naturally mix short and long sentences. Token probability examines how likely each word is in its context. You also get sentence-level feedback, so you can see exactly which parts of the text raised flags. This detailed approach helps you learn what makes AI writing different from human writing.

AI Humanizer

The AI Humanizer tool is designed to take AI-generated text and rewrite it into more natural, human-sounding language. If you have content that feels robotic, repetitive, or too polished, this feature can transform it while keeping the original meaning and tone intact. It works by adjusting word choices, sentence structures, and rhythm to mimic the natural imperfections and variations found in human writing. For example, it can break up long paragraphs, introduce occasional shorter sentences, and vary sentence beginnings. This is especially useful for students, marketers, and professionals who want to refine AI drafts before sharing them. The result is writing that feels authentic and lived-in, without losing the core message.

Comprehensive Writing Tool Suite

AI Detector App is not just a detector. It includes a full set of writing tools to support your entire workflow. You will find a plagiarism checker to ensure originality, a summarizer to condense long texts, a paraphraser to rephrase content, a grammar checker to catch errors, a translator for multiple languages, a word counter for precise length control, an email writer for professional correspondence, an AI image detector for basic image screening, a citation generator for academic references, an essay writer for structured drafts, a readability checker to assess text difficulty, and a sentence rewriter for quick tweaks. All these tools are integrated into one convenient interface, saving you time and effort. Whether you are writing an essay, editing a report, or checking a submission, everything you need is in one place.

Cross-Platform Availability

AI Detector App is available on both the web and iOS, making it accessible wherever you work.

Students Checking Academic Integrity

As a student, you want to ensure your work is original and properly cited. AI Detector App helps you check your drafts before submission, giving you confidence that your writing sounds natural and human. You can also use it to verify sources or peer submissions. The sentence-level feedback shows you which parts might appear overly predictable or AI-like, so you can revise accordingly. The AI Humanizer can then help you rephrase any sections that feel robotic. This is especially useful for research papers, essays, and reports where authenticity matters. The tool also includes a citation generator and plagiarism checker, making it a complete academic companion.

Educators Reviewing Student Work

Teachers and professors face the growing challenge of identifying AI-generated assignments. AI Detector App provides a reliable first pass to flag suspicious text. The detailed metrics help you explain to students why a piece of writing might be flagged, turning detection into a teaching moment. You can show them how perplexity and burstiness differ between human and AI writing. The tool also helps you review drafts and provide feedback on writing quality. By using the detector alongside the humanizer, you can guide students toward more natural writing. The readability checker and grammar checker further support your grading and feedback process.

Content Marketers Ensuring Authenticity

Marketers and content creators need to produce authentic, engaging copy that resonates with readers. AI Detector App helps you check blog posts, social media content, and email drafts for overly AI-sounding language. If a draft feels too polished or repetitive, the AI Humanizer can transform it into more natural phrasing. You can also use the summarizer and paraphraser to create variations of content for different platforms. The email writer tool helps you craft professional messages that sound human. By ensuring your content passes detection checks, you maintain trust with your audience and avoid the pitfalls of generic AI writing.

Editors and Compliance Teams Reviewing Submissions

Editors, publishers, and compliance professionals need to verify the originality and authorship of submitted content. AI Detector App provides a fast, reliable way to screen submissions for AI generation. The detailed metrics and sentence-level feedback give you concrete evidence to support your decisions. You can use the tool to review drafts, check for plagiarism, and ensure compliance with content policies. The AI image detector adds another layer of verification for visual content. With the full suite of writing tools, you can also edit and refine submissions directly within the app, streamlining your review process. This saves time and helps maintain high standards for published work.

What is an AI Detector and how does it work?

An AI detector is a tool that analyzes written text to determine whether it was authored by a human or generated by an artificial intelligence model. It works by measuring statistical properties of language, including perplexity (how surprising the word choices are), burstiness (variation in sentence length and complexity), and token probability (how likely each word is in its context). The detector does not read for meaning. Instead, it evaluates patterns in word predictability and sentence structure. Human writing tends to have higher perplexity and burstiness, while AI text is often more uniform and predictable. The analysis happens in seconds, comparing millions of data points against known signatures of machine-generated language. For best results, use text samples of at least 100 to 300 words.

Is AI Detector App free to use?

Yes, AI Detector App offers a freemium model. You can use the core AI detection feature for free, which provides instant analysis with detailed results including perplexity, burstiness, and token probability. The free tier is ideal for quick checks and occasional use. For access to additional tools like the AI Humanizer, plagiarism checker, summarizer, paraphraser, and other writing features, there are premium plans available. You can start with the free version to see if the tool meets your needs, and upgrade later if you require the full suite. The app is available on both the web and iOS, with the same freemium structure across platforms.

Can AI Detector App detect all AI models?

AI Detector App can analyze text generated by most mainstream large language models, including ChatGPT, GPT-4, GPT-4o, Gemini, Gemini Pro, Claude, Claude 3, LLaMA, and Mistral. However, detection accuracy varies depending on the model used. Older models like GPT-3.5 produce text with more detectable patterns, while newer models like GPT-4o and Claude 3 generate output that is harder to flag because they are trained to produce more natural-sounding language. The length of the text sample also matters. Anything under 100 words significantly reduces confidence in the results. No AI detector is 100% accurate, so results should always be verified with human review and source checks.

How accurate is AI Detector App?

No AI detector is 100% accurate, and AI Detector App is no exception. This is a fundamental constraint of the technology, not a flaw in the tool. Detection confidence depends heavily on text length, with longer samples (300 words or more) giving more reliable results. Shorter text produces less reliable outcomes. The app provides detailed metrics so you can assess the confidence level for yourself. It is important to use the results as a guide rather than absolute proof. Always combine detection results with human judgment, source verification, and context. The tool is designed to support your decision-making, not replace it. For best practices, use the detector as a first pass and follow up with manual review.
