About AI text detection
AI text detectors examine stylometric signatures — uniform sentence rhythm, overused transitions ("moreover", "furthermore"), hedge cliches ("it's important to note"), formulaic structure, and the absence of small specifics that humans can't help including. No detector is 100% accurate, and heavy editing can disguise AI output.
The Qaynaq Labs detector returns more than a number: it lists the specific signals it saw in your text, flags suspect passages, and includes honest caveats about reliability. Treat the result as a hypothesis, never as the sole basis for a plagiarism accusation.
Frequently asked
How accurate is AI detection?
Probabilistic, not absolute. Long, untouched AI output is easy to flag; heavily edited or paraphrased text becomes indistinguishable from human writing. Treat any score as a hypothesis.
Is my text stored?
We cache analysis results by content hash to skip re-doing identical requests. The raw text is held only for the time needed to produce the analysis.
Why does it sometimes flag clearly human text?
Some humans write in an AI-adjacent formal style — academic prose, corporate copy, legal text — and trip the same heuristics. The caveats block explains this.
Can I use this to flag students?
Strongly discouraged. Detection alone is not evidence of misconduct. Combine with conversation, drafts, version history, and a fair process.
