Why it is detectable

ChatGPT leaves recognizable traces in Hungarian too.

Assistants like ChatGPT are post-trained toward a helpful, instruction-following style, which makes their writing narrower and more predictable than human text. Preds learned to recognize these patterns on Hungarian text.

Not only ChatGPT

Preds also recognizes text from Claude, Gemini, DeepSeek, Llama, Mistral, Grok and Perplexity, and text rewritten with humanizer tools such as Grammarly or QuillBot.

Benchmark results

OpenAI models generated 102 of the 500 AI texts in the public HuDetect-1k test dataset (88 by GPT-5.6, 14 by gpt-oss-120b). Preds 3 recognized 496 of the 500 AI-generated texts and did not label any human text as AI-written.

Sentence by sentence

If ChatGPT wrote only a few paragraphs, Preds highlights those sentences, so you do not have to judge the whole text by a single percentage.

In practice

The full text stays beside the result.

Preds shows an overall estimate and highlights the sentences that point to ChatGPT. Read them with the surrounding paragraphs before drawing a conclusion.

  1. 01Paste the text, or sign in and upload a PDF or DOCX file.
  2. 02Review the overall estimate and the highlighted sentences.
  3. 03Compare the signal with the writer’s drafts, sources and explanation.

A result is an estimate, not proof that ChatGPT wrote the text. Do not base a grade, hiring or disciplinary decision on it alone.

Questions about detecting ChatGPT text

Does it recognize text written with GPT-5?

In the public HuDetect-1k test dataset, GPT-5.6 generated 88 texts and gpt-oss-120b generated 14. Preds 3 recognized 496 of the 500 AI-generated texts and did not label any human text as AI-written.

What about Gemini, Claude and other models?

The same dataset also includes text generated by Gemini 3.8 Flash, DeepSeek V4 Flash, Kimi K2.6, Llama 4 Scout, Qwen 3.7 Flash, GLM 5.3 Flash, Mistral Small, Claude Haiku 4.5 and Grok 4.3.

Can rewriting or a humanizer get around it?

Paraphrasing and humanizer tools can weaken the signal, but the language patterns often remain. We tested how much the result changes in our own experiment.

How reliable is the result?

No AI detector is infallible. The error rate is higher for short, heavily edited or translated text, so read the result with the text and its context in mind.

Nem, az LLM-ek nem utánozzák az embert!

Csábító azt gondolni, hogy mivel az LLM-eket az emberi szöveg modellezésére tanítják, a kimenetük megkülönböztethetetlenné válik az emberi írástól. A valóságban azonban az LLM-ek nem csupán megközelítik az emberi szöveget: utótanítással (post-training) olyan segítőkész asszisztensekké alakítják őket, amelyek követik az utasításokat, ez pedig egy szűk tartományra korlátozza az írásukat, amely felismerhető marad.
