Oakgen AI Studio · 5 credits per analysis
AI Content Detector
Paste text. Get a probability score, signals, and flagged phrases — verdict on whether it was written by AI. Sign in to use; runs on your Oakgen credits.
How the detector works
The detector analyzes statistical patterns in your text — sentence rhythm, word choice, idiomatic mistakes, hedging, the kind of filler that LLMs over-rely on. Each sentence gets its own score, and the page returns an overall probability with a confidence rating.
No model is perfect. The detector returns a calibrated score, not a binary verdict. Use the result as one signal in a broader judgment — short text, edited AI text, and unusually polished human writing can all produce ambiguous results.
When to use it
- • Editors verifying contributor copy is genuinely written, not LLM-generated
- • Marketers checking whether ad copy or landing pages read as human-authored
- • Writers self-checking output before publishing — catch your own LLM tells
- • Hiring managers screening cover letters and writing samples
- • Readers verifying whether a viral post was actually written by a person

Frequently asked questions
How much does each analysis cost?▾
Each analysis costs 5 Oakgen credits. The free tier gives 1,000 credits at signup — enough for 200 detections. Paid plans start at $9/month and credits work across every Oakgen tool: image, video, music, voice, and analyzer.
Why isn't this free like other AI detectors?▾
Detection runs on a frontier reasoning model — accurate analysis costs real compute. Charging 5 credits keeps quality high and the tool sustainable. The free tier still gets 200 detections at no cost, more than most ad-funded detectors offer before their paywall.
How accurate is the AI detector?▾
The detector returns a probability score with a confidence rating, not a binary verdict. Accuracy is highest on inputs of 200+ words. Short text and mixed human-AI editing can produce uncertain results. Always treat the score as a signal, not proof.
What models does it detect?▾
It looks for stylistic patterns common across modern large language models — uniform rhythm, hedged claims, common LLM filler words, lack of idiosyncratic mistakes. It works on text from any major AI assistant, not just one specific model.
Can the detector be fooled?▾
Yes — heavily edited or rewritten AI text can pass as human. That's why we built an AI Humanizer alongside the detector, so you can see what humanized AI text looks like and judge accordingly.
Do you store the text I paste?▾
We cache the analysis result for 24 hours so repeat queries return instantly without burning compute. The text is hashed for the cache key — we don't keep it in any persistent log or database.
Do unused credits roll over?▾
Yes — unused credits roll forward on every Oakgen plan. You never lose what you paid for, and detection credits work across all of Oakgen's image, video, music, and voice tools.
Is the detector different from a plagiarism checker?▾
Yes. A plagiarism checker compares text against existing sources. An AI detector estimates whether text was generated by a language model. They answer different questions and are typically used together.
Disclaimer: AI detection is probabilistic. Oakgen.ai's detector is a signal, not a verdict — false positives and negatives occur. Do not use this tool as the sole basis for academic, employment, or legal decisions.
