Paste any piece of writing below. Our free AI checker reads its rhythm, word choice, and structure, then gives you a plain result: human, mixed, or AI. No account, no waiting, no catch.
An AI checker is a tool that looks at a piece of text and estimates whether a person or an AI model most likely wrote it. Ours works by studying the small habits that show up in writing: how much sentence length varies, which words get overused, and whether the structure repeats itself in ways a human writer rarely does on their own.
Think of it less like a lie detector and more like a second pair of eyes. It will not read your mind or the model's, but it will point out the parts of a piece that read a little too smooth, a little too structured, or a little too familiar.
People use an AI checker like ours for a few different reasons, and all of them come down to the same question: does this sound like a real person wrote it, or did it come out of a machine?
Whether you are checking your own draft or something someone sent you, using our free AI checker takes less than a minute.
Drop in an article, an essay, an email, or a paragraph you are unsure about. Twenty five words or more gives the checker enough rhythm to read.
Click once. The AI checker scans sentence rhythm, word choice, and structure right there in your browser. There is no upload and no waiting on a server.
You get a plain human, mixed, or AI result, along with the exact sentences that pulled the score in that direction, so you know what to look at.
A content AI check is not just for catching cheating. Here is who actually uses one day to day.
Run a quick check on a draft before it goes out, and rewrite any part that reads too stiff or too templated.
Check your own essay before you turn it in, so you can be sure it sounds like your own voice, not a generated one.
Screen incoming submissions or freelance copy for AI-heavy sections before you commit to publishing them.
Keep a consistent, human voice across a site by checking pages before they publish, not after readers notice.
Every check gives you a single AI likelihood score from 0 to 100, plus one of three plain labels.
Alongside the score, the checker highlights the exact sentences that raised the AI score, so you are never just staring at a number with no explanation behind it.
No single word or sentence proves anything on its own. Our AI detector combines several signals and weighs them together, the same way an experienced editor would notice several small things at once rather than one big one.
Human writing mixes short and long sentences. AI writing tends to keep a steadier, more even pace.
Certain words show up far more often in AI writing than in ordinary human writing, especially in dense clusters.
The checker looks for the same short phrases reused across a piece, a habit that shows up more in generated text.
Patterns like rule of three lists, "it's not just X, it's Y," and stock summary lines are counted, not just guessed at.
Formulaic use of dashes and other punctuation, more frequent and more evenly placed than most people write by hand.
Yes. You can paste your text and run a check without creating an account or paying anything. We built this as a free AI checker and free AI detector that anyone can use on any piece of writing.
The AI checker looks at sentence rhythm, common AI phrasing, repeated word patterns, and structural habits such as em dashes, rule of three lists, and stock summary lines. None of these signals alone proves anything, but together they form a pattern that leans human or AI.
Yes. Many writers and site owners run a quick content AI check on drafts before publishing, so they can catch AI sounding phrasing and edit it into their own voice first.
No detector, including ours, is 100 percent accurate. Results are a statistical estimate based on writing patterns, not proof. Treat a high AI score as a reason to review the text, not a final verdict.
The check runs in your browser. We do not require an account and we do not publish or share the text you paste in to run a check.
Paste your text into the AI checker above and see your result in seconds. It is free every time, not just the first one.
