Not just a percentage. A usable answer.

Preds clearly shows which parts are suspicious in a text.

01

Sentence-level transparency

Alongside the overall result, suspicious and human-classified sections are highlighted separately passage by passage.

Who is Preds for?

Six ways to review Hungarian writing. Find the one that fits your work.

The result is an estimate, not proof. Review the complete text and its context before making a decision.

From Hungarian researchers - The best possible solution

Preds is built exclusively on Hungarian-language data. We continuously measure and improve our methodology and models.

01

Verified accuracy

Preds detects AI-generated content in texts with 98% accuracy. Measured on nearly 100,000 documents.

02

Data protection

Uploads are protected in transit. Source files are held temporarily for text extraction and deleted afterward; extracted text is encrypted while available for review before submission.

03

Trained on diverse texts

The data on which the Preds model was trained was crafted to include as many domains as possible: news, legal and administrative texts, scientific and educational materials, community content, creative writing, as well as technical and financial texts.

04

Low false positive rate

False positive means flagging human text as AI-generated. This is a critical mistake, which is why our model was designed to keep this error minimal. Based on our tests, it only misclassifies 1 human text out of 1,000 in this direction.

Frequently asked questions

Key questions about accuracy, data handling, and usage.

Preds is built specifically on high-quality Hungarian-language data, taking into account the unique characteristics of Hungarian texts. Alongside high accuracy, we emphasize a low false-positive rate and transparent, sentence-level results.

The Preds model is itself an AI model that learned to distinguish human writing from machine generation on a massive volume of Hungarian texts. It provides a probabilistic result with confidence scores for pasted text and highlights suspicious passages sentence by sentence. The result is a decision-support signal, not definitive proof of authorship.

Preds is free to use: every user receives 2 free credits per day. The daily allowance resets to 2 credits each day and unused free credits do not roll over. No credit card is required to sign up. For larger volumes, subscriptions or credit packages are available.

Yes, no AI detector is infallible. In our internal Hungarian-language benchmarks, accuracy exceeds 98% measured across nearly 100,000 independent texts, but the margin of error is higher for short, heavily edited, or translated texts. Results should therefore be evaluated with discretion alongside additional context.

Preds recognizes text written by ChatGPT, Claude, Google Gemini, DeepSeek, Meta AI, Grok, Llama, Mistral, Perplexity, and Deep Research artificial intelligence. In addition, it detects "humanizer" tools such as Grammarly and QuillBot.

Yes, detection from files is supported. We support TXT, PDF, DOCX, Markdown, and image formats. Detection can also be run on handwritten texts, which is available in the Essential and Pro subscriptions.
