Built for Academic Writing

Purpose-built AI detection for essays, papers, and long-form content with detailed, actionable reports.

Essay-Focused AI Detection

Purpose-built for academic writing. Analyze essays, research papers, assignments, and long-form content for AI-generation patterns with high accuracy.

Sentence-Level Breakdown

See exactly which sentences are flagged as AI-generated. Detailed per-sentence scores help you pinpoint specific passages rather than relying on a single document-level verdict.

Calibrated Confidence

A 90% score means roughly 90% likely AI, not a number rounded up to sound decisive. Where the signal is weak, the verdict says uncertain rather than guessing.

Fair for All Writers

Calibrated to minimize false positives, especially for ESL and non-native English writers. Detection focuses on AI patterns, not writing proficiency.

Confidence Scoring

Every result includes a clear verdict with confidence indicators, so you can make informed decisions about the content you're reviewing.

Multi-Model Detection Engine

We run each essay past several detection models that check different things, then combine their verdicts. No single model makes the call on its own.

How It Works

Get a complete analysis in three simple steps.

1

Paste Your Essay

Submit the essay or academic writing you want to check by pasting the text directly. The minimum is 50 characters, and longer passages give more reliable results.

2

AI Detection Analysis

Our engine looks for the habits that give AI writing away: unusually predictable word choices, sentences that all run to a similar rhythm, and a tone that stays flat from start to finish.

3

Review Your Results

Get a clear, actionable report showing which sections are likely AI-generated and which appear to be original human writing, with confidence scores throughout.

Frequently Asked Questions

Our engine looks for the patterns that separate AI writing from human writing. AI tends to pick the most predictable next word and to keep every sentence at a similar length and rhythm, where people vary far more. Several models each check for different signs, and we combine their verdicts rather than trusting any one of them.

Our detection engine identifies AI patterns even in lightly paraphrased text. However, heavily rewritten or manually edited content may be harder to detect. This is an inherent limitation of all AI detection tools. We provide confidence levels to help you interpret results.

The minimum is 50 characters. Longer texts generally produce more accurate results because there are more sentences to analyze, so a full essay gives a far more dependable verdict than a single paragraph.

Yes. We've specifically calibrated our models to reduce false positives for ESL and non-native English writers. Our detection focuses on AI-generation patterns rather than writing quality or proficiency level.

Our tool returns one of four verdicts: 'Likely AI' means the text shows strong AI-generation patterns, 'Possibly AI' indicates some AI patterns detected, 'Uncertain' means the result is inconclusive, and 'Likely Human' means the text appears to be human-written. Each verdict comes with a confidence score.

Not at the moment. Our models are trained and benchmarked on English prose, so we do not make accuracy claims for any other language. We would rather ship language support than promise it.

Plagiarism detectors compare text against existing sources to find copied content. AI essay detection analyzes writing patterns to determine whether text was likely generated by an AI model like ChatGPT. The two tools solve different problems and are complementary.
