What is an AI Content Detector?

Our AI detection tool analyzes text for statistical patterns associated with large language models and returns a probability score showing how likely the content was written by AI.

This tool returns an AI Score showing the percentage of content estimated to be AI-generated versus human-written, alongside a sentence-by-sentence breakdown of flagged lines.

What you get

What Our AI Detector Report Shows You

Your free AI detector gives you an AI score, a sentence-by-sentence breakdown, and flagging estimates for the four detection platforms most commonly used by institutions and publishers.

Total AI Score

Your report opens with a percentage showing how much of your text was estimated to be AI-generated.

Human-Written Percentage

Alongside the AI score, the report shows the share of your text that reads as human-written, giving you the full picture at a glance.

Sentence-Level Breakdown

Every flagged sentence is highlighted in color. Click any highlighted sentence to rephrase it directly, and your AI score drops as you fix each line.

Platform Estimates

The report shows how likely your content is to be flagged by each of the four major detection platforms, rated High, Medium, or Low. Your text is not submitted to any of them.

How it works

How To Use AI Detector Tool

Spot AI-generated content in three steps. Results arrive in under 15 seconds, no sign-up required.

  1. 1 Paste or upload

    Paste or Upload Content

    Paste your text into the input box or upload a PDF or DOCX file. The free tier handles up to 1,500 words per check without an account. First time? Click Try Sample to load an example.

  2. 2 Under 15 seconds

    Click Detect AI Content Button

    This will start the scan. The tool checks your text for patterns from ChatGPT, Gemini, Claude, and other large language models. Results usually arrive in under 15 seconds.

  3. 3 Sentence-level report

    Review Your Report

    Check your AI Score, the sentence-level breakdown, and the four platform estimates. Click any highlighted sentence to rephrase it. Run the detector again to track your improvement.

Tips

  • For the most reliable score with our AI detector tool, submit at least 300 words. Short passages produce less stable results.
  • Formulaic writing, including academic definitions, legal phrasing, and structured templates, can score higher than expected.
  • Treat every result as guidance, not a final verdict. Every score is a probability estimate, not confirmed proof of authorship.
Reliable Accuracy

How Accurate is Our AI Content Detection?

This detector returns 87–88% accuracy in standard conditions, making it one of the more reliable AI detector tools available for free. No AI detector achieves 100%.

Trained on the Latest LLMs

Covers ChatGPT, Gemini, Claude, and other leading LLMs, giving the best AI detector coverage across today's most-used writing tools.

Consistently Updated

The detection model updates as new LLM versions are released, keeping it effective against AI writing styles that older detectors may miss.

Advanced Linguistic Analysis

Pattern recognition works at the sentence level, lowering the false positive rate on mixed human and AI writing.

Questions

FAQs About the AI Content Detector

Is the AI content detector free to use?

Yes, our detector is free for up to 1,500 words per check. You can start detecting AI-generated content by running 3 checks without creating an account. Creating a free account removes that limit and gives you unlimited AI detection checks, with no credit card required.

Do I need to sign up to check for AI?

No. You can run 3 checks without an account, each up to 1,500 words. Creating a free account takes under a minute and removes the check limit entirely. Paid plans include unlimited detection alongside MyEssayWriter.ai's full set of 30+ writing tools.

What does the AI percentage score mean?

The percentage is the share of your text the detector estimates was generated by an AI model. A score of 80% means the tool found AI-associated patterns across approximately 80% of the text. The score is a probability estimate, not a confirmed finding. Use the sentence-level breakdown to see which specific sections drove the score.

Can this tool detect mixed AI and human-written text?

Yes. The sentence-level breakdown identifies individual sentences that appear AI-generated alongside those that appear human-written. This makes it possible to review a document that mixes your own writing with AI-assisted passages and pinpoint the specific sections that need revision.

What are the limitations of AI content detection?

AI detection is probabilistic. No detector can determine with certainty whether a human or an AI wrote a piece of text. This tool returns 87–88% accuracy in standard conditions. Scores on very short texts are less stable; formulaic human writing can score higher than expected, and heavily paraphrased AI content can score lower. Treat results as guidance, not proof.

What is the difference between an AI detector and a plagiarism checker?

An AI detector checks whether text was likely written by AI, while a plagiarism checker checks whether text was copied from an existing source. Understanding how AI detectors work helps clarify the distinction. An AI detector identifies AI-generated content by looking for patterns associated with large language models. A plagiarism checker compares your text against published web pages, articles, and academic papers to find copied passages. A trusted AI checker will always present results as estimates, not proof. Use our plagiarism checker alongside this tool for a complete check before submitting.

Does the AI content detector support multiple languages?

Yes. The detector supports 25 languages. You can paste or upload text in any supported language and the tool will analyze it for AI patterns. The output format is the same regardless of the language you submit: AI Score, sentence-level breakdown, and four platform estimates.

Will my text be stored or shared?

No. Text you submit is analyzed in real time and discarded after your results are returned. Checking without an account requires no personal information. Your content is not shared with any third parties, including GPTZero, Turnitin, Copyleaks, and Originality, the four platforms whose flagging probability your detection report displays.

How do I reduce my AI score?

Click any highlighted sentence in your detection report to rephrase it directly in the tool. Your AI score updates as you fix each line. For deeper rewrites, run flagged sections through the AI humanizer, which rewrites AI-sounding text to read as naturally human-written. Then run the detector again to check the improvement.
