Understand your score
What does your AI detection score mean?
Your AI detection score shows how much of your text our detector identifies as likely AI-generated. Use it as a useful signal when reviewing your content, not as definitive proof of how the text was written.

How it works
How our AI Detector works
Our detector analyzes your text using multiple linguistic and structural signals to estimate how strongly it matches characteristics commonly associated with AI-generated writing.
Analyze the text
The detector evaluates your text as a whole, looking at its language, sentence structure and other characteristics rather than relying on isolated words.
Analyze AI-related signals
Our system evaluates multiple linguistic and structural signals that can appear in AI-generated or AI-assisted writing, including patterns in predictability, sentence variation, wording and style consistency.
Generate your score
These signals are combined to produce an overall AI detection score from 0 to 100, showing how strongly the text matches characteristics commonly associated with AI-generated writing.
Signals analyzed
Multiple signals. One result.- Perplexity
Text predictability and how naturally word sequences vary throughout the writing.
- Burstiness
Variation in sentence length, structure and rhythm throughout the text.
- Linguistic patterns
Recurring wording, phrasing and stylistic characteristics found across the text.
- Structural consistency
How consistently the writing follows similar sentence and structural patterns throughout the text.
- AI watermark signals
Supported watermark or provenance signals, when they are present in the content.
AI detection is based on patterns and signals in the analyzed text, so results should always be interpreted in context.

See why people check their text with AI-2-Human
From students and teachers to writers and content teams, AI-2-Human helps people understand the AI signals in a text before they submit, publish or review it.
I check my essay draft with AI-2-Human before I hand it in. The score tells me how much of it reads as AI-generated, and the explanation tells me what pushed it up.
My AI-assisted articles come out too even. Checking them here first tells me whether the draft needs another pass before I publish it.
We check marketing copy before it goes out. It is a quick read on how strong the AI signals are, and the score is easy to explain to the team.
I read the score as one more piece of context when I review submitted work, never as a conclusion on its own.
It saves me time on the first read. The explanation points at wording and structure, which is where I actually start editing.
We added it to our publishing checklist. Every draft gets a score before it goes to review, and that made our process clearer.
I use it to see whether my notes still sound like something I wrote, rather than like a model wrote them.
It gives me a number to look at, not a verdict. I still read the work and decide for myself.
Reports and internal documents pass through it before they circulate. The score is a fast signal, and the explanation is what I really read.
I check a draft before I send it to an editor. Knowing how strong the AI signals are tells me how much rewriting to expect.
It is the first thing I run on a client draft. The score either confirms my instinct or tells me to look closer.
Our team reviews a lot of AI-assisted content. A shared score makes those conversations shorter and less subjective.

FAQ
Frequently asked questions about AI detection
Clear answers about how AI-2-Human detects AI-generated writing, how to read your score, and how to use the results responsibly.
What is an AI detector?
An AI detector is a tool that analyzes text for patterns and signals commonly associated with AI-generated or AI-assisted writing. AI-2-Human uses multiple linguistic and structural signals to produce an overall AI detection score that helps you understand how strongly the text matches those patterns.
How does an AI detector work?
AI detectors analyze characteristics such as text predictability, sentence variation, wording patterns, structural consistency and other linguistic signals. AI-2-Human evaluates multiple signals together rather than relying on a single test, then combines them into an overall detection result.
How accurate are AI detectors?
AI detectors are useful for spotting patterns associated with AI-generated writing, and the score is a practical signal when you are reviewing a text. No detector should be treated as absolute proof of authorship, though: results can vary with the text, the writing style, how heavily it was edited and how much content was analyzed.
Can AI-2-Human detect ChatGPT text?
AI-2-Human can analyze text created with ChatGPT and other AI writing tools, because it looks at how the text is written rather than at a signature left by one product. Paste the text into the detector to get an AI indication score, then read the result in context.
Can AI-2-Human detect Claude, Gemini and other AI models?
The detector reads writing patterns, so it is not tied to one tool or one model. Text from ChatGPT, Claude, Gemini and other modern AI writing systems can be analyzed the same way, as long as it shows the linguistic and structural signals the detector looks for.
What does an AI detection score mean?
Your AI detection score shows how strongly the analyzed text matches patterns commonly associated with AI-generated writing. A higher score indicates stronger AI-related signals; a lower one indicates fewer. Use it as a review signal rather than as definitive proof of who or what wrote the text.
Can human-written text be flagged as AI?
Yes, human-written text can sometimes receive a higher AI indication, especially when the writing is highly structured, repetitive, predictable or heavily edited. That is why a result is best read alongside the context of the text rather than as a standalone verdict.
How much text should I use for an AI detection scan?
There needs to be enough text to read meaningful language patterns. The detector requires at least 50 words, and a full paragraph or more gives the most informative result. Guests can analyze up to 500 words at a time; very short passages carry fewer signals.
Is the AI Detector free?
Yes. Guests get 15 detections every 24 hours, and a free account keeps the same daily limit. You can paste your text, run the analysis and review your result without committing to a paid plan, which raises the daily limit.
Do I need an account to use the AI Detector?
No account is required to start. You can paste your text and check it right away as a guest, with the same daily limit a free account gets.
Does AI-2-Human save my AI Detector history?
No detection history is saved to your account. You can analyze your text, review the result and move on without building up a list of previous detections.
Is my text private when I use the AI Detector?
AI-2-Human does not save a detection history to your account. Your text is processed to produce the detection result, and nothing about it is stored as a detection you could look up later.
Can I use an AI detector for essays and academic writing?
Yes. AI-2-Human can review essays, assignments and other academic writing for AI-related signals. Treat the score as an additional review signal rather than as proof of authorship or misconduct.
Can teachers and educators use the AI Detector?
Yes. Educators can use AI-2-Human as one more signal when reviewing student submissions and written assignments. A result should always be read alongside the writing context and whatever else you know about the work.
Can writers and content teams use the AI Detector?
Yes. Writers, marketers and content teams can use AI-2-Human to review AI-assisted drafts, articles, marketing content and professional writing before publishing or sharing them.
What should I do if my text gets a high AI detection score?
Start by reading the explanation that comes with the score, then review the wording, the sentence structure and the overall flow of the text. If you want to refine AI-assisted writing, the AI-2-Human Humanizer can make it feel more natural while keeping your original meaning.
