How accurate is the AI content detector?

The detector returns a calibrated probability score with a confidence rating, not a binary verdict. Accuracy is highest on inputs of 200+ words. Short snippets, heavily edited AI text, and unusually polished human writing can all produce uncertain results, so treat the score as a strong signal rather than proof.

Which AI models can it detect?

It looks for stylistic patterns common across modern large language models — uniform rhythm, hedged claims, telltale filler, and a lack of human idiosyncrasy. That means it works on text from ChatGPT, Claude, Gemini, and other major AI writers, not just one specific model.

Is the AI detector free to use?

You can start on the free tier with a limited number of starter credits — enough to check plenty of text at no cost. Paid plans begin at $9/month and unlock more monthly credits, and the same balance works across every Oakgen tool: image, video, music, voice, and analysis.

Do you store the text I paste in?

Your text is processed only to produce the detection result. We don't sell it, train public models on it, or keep it in a public log. Results may be cached briefly so repeat checks return instantly, and the text is hashed for the cache key rather than stored in plain form.

Can the detector give false positives?

Yes — no AI detector is perfect. Genuine human writing that is very formal or formulaic can occasionally read as AI, and heavily edited AI text can pass as human. Always use the result as one input alongside your own judgment, never as the sole basis for an academic, hiring, or disciplinary decision.

AI Content Detector

Paste any text and find out if it was written by AI. A fast, free AI content detector and ChatGPT detector that scores text for AI-generated patterns, flags the giveaway phrases, and tells you whether it reads human — your go-to AI checker and AI text detector for the question "is this written by AI?"

A clear verdict, not a guess

Paste your text and get an overall AI-probability score with a confidence rating — likely human, mixed, or likely AI — instead of a vague yes/no. Read it as a signal, backed by the reasons behind it.

See exactly what looks AI

The detector surfaces the specific signals and flagged phrases that tipped it off — robotic rhythm, hedged claims, telltale filler — so you understand the call rather than trusting a black box.

Works on any model's output

It targets the stylistic patterns shared across modern language models, so it flags text from ChatGPT, Claude, Gemini, and the rest — not just one specific AI writer.

One workspace, one balance

“I grade 90 essays a week. Pasting a suspect paragraph and seeing the exact phrases it flags gives me something concrete to talk to the student about — not just a gut feeling.”

PNPriya N.High school English teacher

“Before I submit, I run my own draft through it. If it comes back 'likely AI' I know I over-relied on the assistant and need to rewrite in my own voice. Saved me from an awkward conversation.”

MTMarcus T.University student

“We get hundreds of freelance pitches. A quick AI check tells me which writers actually wrote their sample and which just pasted ChatGPT. It's now the first step in our screening.”

ERElena R.Managing editor

“Cover letters started reading suspiciously similar. The detector flags the generic LLM filler instantly, so I can focus my time on candidates who clearly wrote their own application.”

DODavid O.Technical recruiter

“I run a small content team and need everything to sound human before it ships. The per-phrase breakdown shows my writers what to fix, not just that something's off.”

ASAiko S.Content lead

“As a tutor I use it to teach, not to accuse. We paste a paragraph together and talk through why it reads as AI — the hedging, the rhythm. It's become a genuine writing lesson.”

TGTomás G.Writing tutor

“A viral post on our forum felt off, so I ran it. 'Likely AI, high confidence' with the filler words highlighted. Confirmed what my gut already suspected in about three seconds.”

HKHana K.Community moderator

“I vet guest articles for our blog. The detector plus the humanizer in the same place means I can flag AI drafts and show contributors how to make them read like a real person.”
