Digital Content Authenticity Suite

Certentis.
Detect AI. Verify Content Authenticity.

Q: Do I need to use all three tools together?

No. The AI detector, plagiarism checker, and Humanizer are fully standalone tools. You can run only the analysis you need or review multiple checks sequentially for the same document.

Q: Does the AI detector prove who wrote a text?

No. The AI detector evaluates statistical language patterns to output probabilities. Results serve as indicators for review and should never be treated as absolute proof of authorship, deception, or content quality.

Q: What do the Human, Mixed, and AI scores mean?

These three figures represent class probabilities for the complete document rather than exact sentence percentages. Certentis displays them alongside sentence-level signals to help you interpret results in context.

Q: How does the plagiarism checker work?

Paste your text or upload a supported document. The report highlights matching passages, links them to web sources, and shows exact overlapping text so you can evaluate citation context.

Q: What does the Humanizer do?

The Humanizer rewrites AI text into natural language in the same original language. It preserves key terminology, meaning, and citations while offering side-by-side comparison for final review.

Q: Which languages are supported?

Certentis automatically detects input language and tailors analysis or rewriting accordingly. Workspace language support may vary by specific tool and document format.

Q: Where can I find past scans and reports?

Signed-in users can access prior humanized texts and analysis reports in their personal history, keeping original drafts, results, and detailed metrics linked in one place.

Certentis integrates AI detection, plagiarism checking, and controlled rewriting in a single workspace. Analyze language patterns, trace source matches, and refine AI drafts transparently.

Text integrity in one workspace

One text. Three checks.

A single score does not explain a text. That is why Certentis presents intermediate results, differences, and sources so you can evaluate them yourself.

AI Detector

How accurate are AI detectors?

An AI score is a statistical classification of the overall text pattern. It is neither a sentence ratio nor definitive proof of authorship.

Plagiarism Checker

Similarity is not automatically plagiarism

A match is a flag for review. Whether content is properly cited, common knowledge, or problematic must be evaluated using the match and source.

AI Humanizer

Natural does not mean oversimplified

For academic, professional, and editorial texts. No translation, no blind replacement, and no guaranteed detector score.

Three tools, one clear workflow

From first draft to verifiable result

Use each tool individually or work step-by-step. Certentis separates editing and analysis so results remain clear and controllable.

AI Detector

Scan texts independently of Humanizer. View class probabilities for Human, Mixed, and AI alongside highlighted passages in context.

Discover AI Detector

Plagiarism Checker

Check pasted text or documents against accessible sources. The report displays overlaps, matched passages, and related sources in a dedicated workspace.

Discover Plagiarism Checker

Humanizer

Refine existing AI text to sound more natural and fluent. The input language is detected automatically; detected quotes and formal references are protected, while meaning and terminology remain visible for final review.

What makes Certentis different

A single score does not explain a text. That is why Certentis presents intermediate results, differences, and sources so you can evaluate them yourself.

Original remains visible

When humanizing, compare the original text and rewrite directly instead of accepting an opaque output.

Probabilities are explained

AI detection is presented as statistical classification, not definitive proof of authorship or quality.

Matched passages link to sources

Plagiarism matches remain linked to specific text passages and accessible sources.

Open evidence

Read the metrics. Review the method. Know the limits.

Certentis separates results, test protocol, and product comparison so it remains clear what was measured and what the test cannot establish.

Evidence status for all three tools

Humanizer	Benchmark published	Quality, semantics, language, length, citations, and external AI classification were checked in one run.
AI Detector	Output documented	Certentis shows document probabilities and sentence signals. We do not claim an independent proprietary accuracy benchmark.
Plagiarism Checker	Report structure documented	Matches, sources, and overlap are shown transparently. Complete coverage of the web is not promised.

Analyze digital content in its original language and understand full editorial context

Certentis detects the input language automatically. Analysis and rewrites stay aligned with the source text so English, German, or multilingual content is never accidentally translated.
