Benchmark published
Humanizer
Quality, semantics, language, length, citations, and external AI classification were checked in one run.
Benchmark hub
What Certentis can substantiate today.
We publish only metrics produced by a documented test. Where no robust accuracy benchmark exists yet, we show the current evidence status instead of inventing a percentage.
Internal, versioned benchmark · Updated July 28, 2026. These results describe this test run. They do not guarantee the same outcome for every text, language, or future product version.
Humanizer · archived run with 10 cases
A result needs context.
The Humanizer test combines quality review, semantic comparison, language checks, word ratio, citation checks, and an external AI analysis. No single metric decides the outcome.

Evidence status for all three tools

AI Detector
Certentis shows document probabilities and sentence signals. We do not claim an independent, proprietary accuracy benchmark.
Report structure documented
Plagiarism Checker
Matches, sources, and overlap are shown transparently. Complete coverage of the web is not promised.
What this page explicitly does not claim
- 01An AI score does not prove authorship.
- 02A plagiarism report may not find every source that exists.
- 03A strong average does not guarantee an error-free individual result.
- 04An internal benchmark is not a substitute for independent scientific validation.
Certentis Evidence
Evidence before promises.
Results, test rules, and limitations are kept separate so it remains clear what was measured and what was not.
