Certentis AI analysis
Sample textHybrid teaching formats combine in-person sessions with digital self-study phases. This combination measurably raises how satisfied students are with the course. (Medium sentence signal) Whether it also improves learning outcomes depends heavily on supervision. What matters is how regularly instructors give feedback on the self-study phases. (Strong sentence signal)
A signal, not proof. The three values are probabilities for the whole document, not shares of the text.
Everything about the AI detectorCertentis is a workspace for the authenticity of digital text. The AI detector estimates whether a text was more likely written by a person or by AI. The plagiarism checker finds overlaps with sources and links to them. The Humanizer rewrites existing text in the same language. All three tools work on their own and share one credit balance.
No account needed. You get a real result, not demo values.
Protected processingAbuse prevention using a necessary device cookie and a pseudonymized network signal. Your text never ends up in advertising or analytics.

Human, Mixed and AI are probabilities for the whole document, not shares of the text. Sentence signals show where to look more closely.
A signal for your own review, not proof.
The plagiarism checker links every overlap to its source and shows the matching passage. Similarity is not automatically plagiarism.
Words per tool for a real test, with no sign-up at all.
The interface comes in 28 languages. Certentis detects the language of your text automatically.

When signed in, you'll find analyses, plagiarism reports and rewrites in your personal history. Original and result stay linked.
The AI detector and the plagiarism checker give you pointers for a decision you make yourself.
AI detector
The Certentis AI analysis gives probabilities for the whole text and signals for individual sentences, not a verdict. Text a person wrote can show AI signals too, such as formulaic technical writing or text written in a second language. A high value is a reason to ask questions, not proof of who wrote the text.
Plagiarism checker
A match is a signal to review, not proof of plagiarism. Compare the passage with the original source to decide whether it is correctly quoted, properly paraphrased, common knowledge, or problematic.
The Humanizer rewrites an existing text in the same language, for example a stiff AI draft. It takes particular care to keep the meaning, technical terms, and quotations intact.
It can be observed that urban heat islands in the past decades have significantly grown in importance. As Brandt (2019) shows, “sealed surfaces store heat during the day and release it again at night.” Consequently, it is essential that greening measures in urban planning be given greater consideration going forward.
Urban heat islands have grown sharply in importance over the last decades. As Brandt (2019) shows, “sealed surfaces store heat during the day and release it again at night.” Quote protected Urban planning therefore needs to take greening measures more seriously.
In this example, the meaning, technical terms like “heat islands,” and the verbatim quote stay intact. The result stays in the language of your original.
Original and result side by side, plus the real scanner scores, even when a target was not reached. Certentis does not promise specific scores.
Benchmark from , n = 10, run by Certentis itself
On , Certentis ran its own benchmark with 10 texts and compared itself with 6 other humanizers. Certentis reached an overall score of 85.4 out of 100 and a semantic fidelity of 91.7 out of 100. In 8 of 10 texts, every complete citation stayed character for character intact; the other providers managed 0 to 6. 10 of 10 results were in the correct language. Because Certentis ran and scored the test itself, we publish the results and the method.
Certentis is for everyone who needs to know where a text comes from, which sources it uses and what has changed.
Check submitted work for AI signals and use the result to start a conversation, not to pass judgment. AI detector
See which passages resemble sources and whether your citations hold up before you submit. Plagiarism checker
Check submitted pieces for overlap with other sources before they are published. Plagiarism checker
Assess reports and external content based on traceable signals instead of a single score. AI detector
Rewrite existing AI drafts so they read more naturally, and compare them word by word with the original. Humanizer
Revise texts in their own language without the revision turning into a translation. Humanizer
You wrote the paper yourself and want to check it once more before you submit: are all your sources properly cited, and where does the AI analysis flag something? Certentis reviews and revises your own text. It does not write a paper for you.
Check first which AI tools your institution allows and whether you have to disclose using them.
The plagiarism checker shows where your text overlaps with sources, so you can decide whether a citation belongs there.
The AI detector flags sentences with signals so you can take a second look. That is not a verdict on your work.
The Humanizer rewrites stiff passages in plainer language. It gives quotations and technical terms extra protection, and you compare the result with your original.
Certentis is a workspace for the authenticity of digital text, with three separate tools. The AI detector estimates whether a text was more likely written by a person or by AI. The plagiarism checker finds overlaps with sources. The Humanizer rewrites existing text in the same language. All three draw on one shared credit balance.
No. The AI detector, plagiarism checker and Humanizer are separate tools in Certentis. You run only the check you need, or work through the same text with several tools, one after another.
No. The Certentis AI detector estimates probabilities from patterns in the language. The result is a signal for a closer look, not proof of authorship or of cheating. Always weigh it in context, for example alongside drafts, notes and the history of how the text was written. Certentis does not claim an independent, proprietary accuracy benchmark for its AI detector.
In the AI detector, Human, Mixed and AI are probabilities for which class the whole document belongs to. They do not say what percentage of the text came from AI. The Certentis AI analysis also marks sentence signals, so you can see which passages shape the assessment.
In the Certentis plagiarism checker, you paste your text or upload a supported document. The report marks the overlaps it finds, links each one to its source and shows the affected passages with a similarity score. Similarity is not automatically plagiarism: you decide whether a passage is correctly cited. Complete coverage of the web is not promised.
The Certentis Humanizer rewrites an existing text in the same language and takes care to keep meaning, technical terms and quotations intact. In Certentis' own benchmark from July 28, 2026 (10 texts, self-run), every complete citation stayed character for character intact in 8 of 10 texts. You compare the original and the result word by word, and the report shows the actual Certentis AI analysis scores, even when a target was not reached. Certentis does not promise any particular score.
The Certentis interface comes in 28 languages. Certentis detects the language of a text automatically and runs the analysis or rewrite in that language. The Humanizer rewrites in the same language and does not translate. How well a language is covered can differ by tool and document format.
Signed-in Certentis users find their AI detector analyses, plagiarism reports and Humanizer rewrites in their personal history. Original, result and the available details stay linked there, so you can open a report again later.
Whether you may use Certentis for a term paper depends on the rules of your university and your department. Check beforehand which AI tools are allowed and whether you have to disclose using them. Certentis does not write papers for you. It helps you check your own text for sources and AI signals, and revise it.
Each tool can be tried once a month without an account. After that, you keep working with one account and one shared credit balance.
