AI Text Detector
Paste text and receive a probabilistic AI-writing likelihood report without storing the raw text in saved reports.
Check whether text may be AI-written
AI writing tools can produce polished, repetitive or formulaic text. PhotoProof AI reviews writing-pattern signals and produces an easy-to-read report.
AI text detection is inherently uncertain, especially for short, edited, translated or non-native writing.
What the text report checks
The text analyzer looks at structure, repetition, sentence rhythm and other probabilistic writing indicators.
- AI-writing likelihood
- Repetition and sentence-pattern signals
- Human-review friendly explanation
- No raw text stored in saved reports
Privacy-first text workflow
Submitted text is processed to generate the report, but raw text is not saved in analysis reports.
Saved metadata is limited to report data and text length so users can review history without exposing pasted content.
AI text detector FAQ
Can this prove that text was written by AI?
No. It is a probability estimate and can be wrong.
How much text can I analyze?
The analyzer supports pasted text up to the configured product limit.
Do you store the pasted text?
No raw text is stored in saved reports; only the result and limited metadata are saved.
