AI Detector estimates how likely a piece of text was written by AI. It analyzes your text sentence by sentence, highlighting patterns that are more common in AI-generated writing and giving you a plain-English explanation for each signal. The result is a probability estimate, not a verdict.
What does AI Detector do?
AI Detector scans your text for statistical and stylistic clues that often appear in machine-generated writing. It looks at things like sentence length variation, word predictability, repetition, and unusual phrasing. Then it shows you which sentences look most suspicious and why. You get a percentage estimate and a breakdown you can actually read. This helps you decide whether to trust a piece of text or dig deeper.
How do you use AI Detector?
Using AI Detector is straightforward. Follow these steps:
- Copy the text you want to check. It can be an essay, an email, a blog post, or a social media caption.
- Paste it into the input box labeled "Paste your text."
- Click the "Detect AI" button.
- Wait a moment while the tool analyzes your text.
- Review the results. You'll see an overall likelihood score and sentence-level highlights.
- Read the explanations for each flagged sentence to understand what triggered the signal.
That's it. No account needed, and your text isn't stored.
When should you use AI Detector?
There are several situations where AI Detector can be helpful:
- Teachers and professors reviewing student submissions. You can get a second opinion before having a conversation with a student.
- Writers and editors checking drafts. If you use AI to generate ideas or outlines, you can see whether the final text still reads as human-written.
- Marketers and content managers reviewing guest posts or freelance articles. It helps you spot content that might be low-effort or auto-generated.
- Students who want to check their own work before submitting. If you wrote everything yourself, the tool should show a low AI likelihood.
- Anyone who receives a suspicious email or message and wants to know if it was written by a bot.
Keep in mind that AI Detector is a tool for gathering evidence, not for making final judgments. Use it alongside your own reading and judgment.
What are the limits of AI Detector?
No AI detector is perfect. Here's what you should know:
- False positives happen. Human writing can sometimes look like AI writing, especially if it's very formal, repetitive, or uses common phrases. A high score doesn't prove a text was AI-generated.
- False negatives happen too. AI writing can be edited to sound more human, and the tool might miss it. A low score doesn't guarantee the text is human-written.
- Short texts are less reliable. If you paste only a few sentences, the estimate is based on limited data. Longer samples give better results.
- Non-native English writing can sometimes trigger false positives because of unusual phrasing or simpler sentence structures.
- The tool doesn't know the source. It can't tell you which AI wrote the text or whether it was paraphrased.
Use AI Detector as one piece of evidence. Combine it with your own reading, context, and other checks. If you're a teacher, don't accuse a student based solely on this tool's output. If you're a writer, don't assume your human-written text is safe just because the score is low.
AI Detector is free to use and designed to be transparent. It shows you why it flagged something, so you can decide what to do next. Try it on a sample of your own writing to see how it works.
