FAQ
What is an AI detector (AI checker)?
An AI detector (also called an AI checker) is a tool that analyzes writing patterns and returns an estimate of how likely a text was generated by AI. It's commonly used for essays, blog posts, marketing copy, and internal documents.
How do AI detectors work?
AI detection tools look for statistical signals typical of AI writing (structure, repetition, predictability, and other features). The output is a probability score — it's helpful for review, but it's not absolute proof.
Is this a free AI detector?
This page is a free AI checker demo for quick text checks. Paste your text and run a scan — no sign-up is required.
Can I use this as a ChatGPT detector?
Yes — this AI detector is designed to help detect AI writing from popular models such as ChatGPT and other LLMs. Results are shown as a probability score.
How can I detect AI writing in an essay?
Paste the essay into the AI checker and run detection. If the score is high, review the flagged sections manually for generic phrasing, repetitive structure, and lack of specific details.
Can AI detectors be wrong?
Yes. Any AI detection checker can produce false positives (human text flagged as AI) or false negatives (AI text marked as human), especially after heavy editing or paraphrasing. Use results as guidance, not a verdict.
What is the best AI detector?
The best AI detector depends on your use case (education, publishing, compliance, marketing). A good AI checker is transparent about limitations and provides consistent results on the types of texts you evaluate most.
Do you store the text I paste into the AI checker?
This demo page doesn't provide storage guarantees. For sensitive content, avoid pasting confidential data, or use an internal workflow where you control data handling.
How to use an AI detector for teachers?
Teachers can paste a student submission into the AI checker, review the score, and then inspect the text for patterns (generic transitions, uniform tone, missing personal context). Pair AI detection with normal academic integrity checks.
What text length works best for AI detection?
Longer texts usually produce more stable results because the detector has more signal to analyze. If a text is very short, the AI checker may be less reliable.
