AI Detector App

AI Detector App is a practical, all-in-one tool designed to help you figure out whether a piece of text was written by a human or generated by an AI model like ChatGPT, GPT-4, Gemini, or Claude. It does this by analyzing the text's statistical properties, measuring signals like perplexity (how predictable the word choices are), burstiness (how sentence lengths and structures vary), and token probability (the likelihood of each word appearing in context). The app provides a clear classification result along with detailed, sentence-level feedback so you can see exactly which parts of the text look machine-generated. This makes it especially useful for students who want to double-check their own work, educators reviewing student submissions, editors and publishers verifying content authenticity, marketers ensuring their copy sounds natural, and compliance teams screening drafts for AI involvement. Beyond detection, the app also includes an AI Humanizer that rewrites AI-generated text into more natural, human-sounding phrasing while preserving the original meaning and tone. It offers a full suite of additional 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. AI Detector App is available on the web and on iOS, making it accessible wherever you need it. The app is honest about its limitations, too, reminding users that detection results can be uncertain and should always be verified with human review and source checks.

AI Detection with Detailed Metrics

The core feature of AI Detector App is its ability to analyze text and estimate whether it was written by a human or generated by AI models such as ChatGPT, GPT-4, Gemini, and Claude. It reports key signals including perplexity, burstiness, and token probability to support its classification. The analysis goes beyond a simple yes or no answer, providing sentence-level feedback that highlights which parts of your text show the strongest signs of AI authorship. This granular detail helps you understand exactly why the app made its decision, so you can review and revise specific sections if needed.

AI Humanizer Tool

The AI Humanizer feature is designed to transform AI-generated text into writing that sounds more natural and human. It rewrites sentences and phrases to break the predictable rhythms and safe word choices that often characterize machine output, while carefully preserving the original meaning and tone. This is particularly useful if you have content drafted by an AI that feels too polished or formulaic, and you want it to read as if a person actually wrote it. The humanizer works quickly and provides a revised version you can use directly.

Comprehensive Writing Toolkit

AI Detector App goes far beyond detection and humanization, offering a full suite of writing tools to support common workflows. You get 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 multilingual needs, a word counter for precise length control, an email writer for quick correspondence, an AI image detector for basic image screening, a citation generator for proper references, an essay writer for structured drafts, a readability checker to assess text complexity, and a sentence rewriter for polishing individual lines. All these tools are integrated into one convenient app.

AI Image Detection

In addition to text analysis, AI Detector App includes a basic AI image detector that helps you screen images for signs of AI generation. This feature is useful for quickly checking whether a picture might have been created by an AI model rather than captured by a camera or designed by a human. While it provides a helpful initial screening, the app recommends treating results as a starting point rather than a definitive verdict, especially for complex or highly realistic AI-generated images.

Educators Reviewing Student Submissions

Teachers and professors can use AI Detector App to check student essays, reports, and assignments for potential AI authorship. The detailed sentence-level feedback helps educators identify specific passages that may need discussion with the student, rather than relying on a simple flag. This supports a more educational approach, where the goal is to understand how the student worked and to guide them toward proper attribution and original writing. The app's transparency about detection limitations also encourages thoughtful, context-aware use in academic settings.

Content Editors and Publishers Verifying Authenticity

Editors working for blogs, news sites, or publishing houses can use the app to verify that submitted articles, guest posts, or freelance content is genuinely human-written. The detection metrics provide an objective signal to complement editorial judgment, helping maintain content quality and authenticity standards. When a piece shows high AI probability, the editor can discuss it with the writer or request revisions. The AI Humanizer also comes in handy for polishing any AI-assisted drafts that need a more natural voice before publication.

Marketers Ensuring Natural Brand Voice

Marketing professionals can use AI Detector App to check their copy for unintended AI-like patterns that might make it feel robotic or impersonal. The burstiness and perplexity scores help identify sections where the writing is too uniform or predictable, allowing for targeted rewrites. The AI Humanizer can then transform those sections into more engaging, human-sounding language that better reflects the brand's voice. This ensures that marketing materials, from social media posts to email campaigns, resonate authentically with audiences.

Compliance Teams Screening Drafts and Submissions

Compliance officers and reviewers in regulated industries can use the app as part of their workflow to screen internal documents, external communications, and submissions for AI-generated content. This is especially relevant for industries where transparency about AI use is required, such as legal, finance, or healthcare. The detailed metrics provide a documented basis for decisions, and the app's honest acknowledgment of uncertainty supports a balanced approach that combines automated screening with human review and source verification.

What app checks if text is AI-generated?

AI Detector App is a dedicated tool that checks text for likely AI authorship. You simply paste your text into the app, and it analyzes the writing using metrics like perplexity, burstiness, and token probability. It then provides a classification result along with detailed, sentence-level feedback explaining why the text appears human-written or machine-generated. The app supports detection from major AI models including ChatGPT, GPT-4, Gemini, and Claude.

Is there a free AI Detector online?

Yes, AI Detector App offers a freemium model that gives you instant analysis with detailed results at no cost. You can paste text directly on the web version for a free check, which includes the core detection metrics and sentence-level feedback. For users who need higher volume or additional features like the full writing toolkit, there are paid upgrade options. This makes it easy to try the app and see its value before committing to a subscription.

Who is AI Detector App for?

AI Detector App is designed for a wide range of users who need to verify the authenticity of written content. This includes students checking their own work for originality, educators reviewing student submissions for AI involvement, editors and publishers verifying that content is human-written, marketers ensuring their copy sounds natural and engaging, and compliance teams screening drafts and submissions in regulated industries. The app's additional tools, like the AI Humanizer and writing suite, also make it useful for anyone who regularly works with text.

How accurate is the AI detection?

No AI detector is 100% accurate, and AI Detector App is transparent about this limitation. Detection accuracy depends heavily on factors like text length, with longer samples (over 300 words) providing much more reliable results than short snippets. Newer AI models like GPT-4o and Claude 3 produce text that is harder to detect than older models. The app provides confidence metrics and detailed feedback so you can make informed judgments, but it always recommends verifying results with human review and source checks before making final decisions.
