Free AI Detector
Wondering whether a text was written by a person or by AI? Our free AI detector analyses writing patterns and estimates how likely it is that ChatGPT, Gemini, Claude or another AI model generated it, and highlights the sentences that look most AI-like.
Your result will appear here.
No AI detector is 100% accurate. Treat this score as an estimate, never as proof, and do not use it alone to make academic or hiring decisions.
How to use the AI content detector
- Paste at least 40 words of text (more text gives a more reliable result).
- Click Detect AI.
- Read the AI score, the verdict and the highlighted sentences, then judge the text in context.
What the AI checker looks at
Burstiness
People naturally mix long and short sentences. Very uniform sentence length is a common AI pattern.
Predictable phrasing
Overused transitions and stock phrases appear far more often in AI writing.
Personal detail
Specific experiences, opinions and informal touches are more typical of human writing.
Sentence highlights
See which sentences raise the score so you can review or rewrite them.
Clear verdict
Likely human, mixed, or likely AI, with a percentage score.
Free and fast
Check text instantly without an account.
Important: AI detection is an estimate
No AI detector, including ours, is 100% accurate. Human writing can be flagged as AI (a “false positive”), especially formal or non-native English, and edited AI text can pass as human. Use the score as one signal among others and never as the only proof in academic, hiring or legal decisions. If your own writing is flagged, keep drafts and notes that show your writing process.
Frequently asked questions
Can this tool detect ChatGPT?
It looks for patterns that are common in text from ChatGPT and other large language models. It gives a likelihood, not a guarantee.
How accurate is the AI detector?
Accuracy depends on text length and style. Longer samples (150+ words) give more reliable results. Treat every score as an estimate.
Why was my human-written text flagged?
Formal, repetitive or template-like writing can look AI-generated. Adding personal examples and varying sentence length usually reflects a more natural style.
Is the AI detector free?
Yes. You can check text for free without signing up.
