What is AI Text Detector?
AI Text Detector is an AI content analysis tool for writers, bloggers, editors, students, and website owners who want to check AI percentage before publishing. It works like an online AI checker, AI content checker, AI generated content checker, and human written text checker, but the wording stays realistic: the result is an estimate based on visible writing patterns, not a guaranteed verdict.
AI vs human text checker
Compare AI like patterns against human writing signals such as detail, examples, personal texture, uneven rhythm, and specificity.
Privacy friendly review
The tool does not require login, database, or AI API. Pasted content is analyzed in the browser and is not saved by default.
How scoring works
How the AI Text Detector works
A useful AI score needs more than one signal. This AI probability checker reviews measurable text patterns and combines them into an estimated percentage. It checks predictable wording, repeated ideas, sentence rhythm, generic phrases, evidence, topic depth, and the amount of specific human detail.

What the AI percentage means
The AI percentage is a content probability estimate. A higher score means the text contains more patterns commonly found in AI generated writing, such as repeated ideas, smooth but generic explanations, safe claims, and low specificity. A lower score means the text contains more human like signals, but it still does not prove authorship.
Review the result with context
Use the AI score checker as a first pass. If a result looks high, review the signal breakdown, add real examples, reduce repetition, include evidence where needed, and make the content more useful for readers. For important academic, employment, or legal decisions, never rely on an AI detector online as the only source of truth.

Helpful review tips
Get practical notes for improving thin, repetitive, or overly polished content before publishing.
AI detector limitations
AI generated content can be edited, rewritten, or mixed with human writing. Human written text can also be polished, generic, or repetitive. That is why AI Text Detector uses terms like probability, estimate, and content signals instead of making absolute claims.

FAQ
Common questions
What is AI Text Detector?+
AI Text Detector is an online AI content checker that estimates whether pasted text looks human written, AI assisted, or AI generated based on writing pattern signals.
How does the AI percentage checker work?+
The tool reviews signals such as repetition, burstiness, sentence variation, generic wording, specificity, structure, and factual density, then combines them into an AI probability estimate.
Is AI Text Detector 100 percent accurate?+
No. AI detection results are estimates. The score should help with review, but it should not be used as the only proof that content was written by AI or by a human.
Does the tool store my text?+
No pasted text is saved by default. The checker is designed for privacy friendly content analysis, and only a report can be saved locally if that option is enabled.
Check AI percentage before you publish
Paste your draft into AI Text Detector, review the AI content probability, and use the signal breakdown to improve clarity, originality, and usefulness.
