AI TEXT CHECKER
Review text for AI writing signals
Free AI-text signal review · browser-local
Paste text to inspect patterns commonly reviewed when assessing AI-assisted writing: repeated phrasing, sentence rhythm, vocabulary, punctuation and hidden Unicode. You get explainable measurements—not a made-up authorship probability.

What the local check returns
AI signals you can inspect—not a verdict you have to trust
The report explains what was measured and keeps three questions separate.

No AI probability score. This release describes signals but does not claim who wrote the text.

Optional model
Named local detector is not in this release
The deterministic report above works now. A model button will appear only after the exact weights, hosting, formatting tests and held-out model card pass release review. No placeholder probability is shown.

Patterns need a benchmark
Sentence rhythm, repetition, vocabulary and mechanics can be measured. They become an AI-associated result only against a named, versioned and independently tested benchmark. Until that exact card exists, this release shows descriptions, not a combined score.
P · page
Metadata is literal evidence
A generator tag or framework signature can say how a page was assembled. Missing metadata says nothing about a human author, and a popular font or rounded card is not a provenance claim.
Q · quality
Help the reader, not the detector
Quality findings point to repetition, long sentences, malformed Unicode and weak structure. They never promise that an edit will “beat” a detector and they do not rewrite your text.

What this cannot tell you
- A pattern match does not prove who wrote, edited or approved the text.
- Page builders, fonts and metadata describe a page, not the authorship of its words.
- Do not use this report as the sole basis for an academic, employment, moderation, publication or legal decision.
- Short, mixed-language, translated and heavily formatted text may produce findings without an eligible benchmark result.
