Short answer

This public detector checks a passage without an account. The form accepts up to 50,000 characters, but the current server forwards only the first 15,000 characters for analysis. Use a shorter passage, protect sensitive information and treat the output as an estimate rather than proof of authorship.

Is this AI detector free?

The inspected public workflow does not require an account. Request controls still apply. Free access is not a claim about unlimited use, accuracy or suitability for every language. The input allowance and the amount actually analysed are different limits.

What happens to submitted text?

The current implementation sends text to an external model provider. Provider and infrastructure retention have not been verified. Do not submit confidential, personal or unpublished material unless you are authorised to share it with that service.

How should I use the result?

Read the passage and its sources. An estimate cannot establish the complete writing process. If a teacher or editor raises a concern, the report should support a clear explanation and a fair opportunity for the writer to respond.

A separate detector estimate

Walter Writes advertises a free detector. It can provide a separate estimate on text you are authorised to share, but it cannot reveal a private school report or establish the full writing process. Check permission before uploading material to another provider.

How It Works

Three simple steps to verify your content

The tool estimates whether writing patterns resemble AI-generated text. Its output cannot establish who wrote a passage.

1

Submit Your Text

The form accepts up to 50,000 characters, but only the first 15,000 are sent for analysis. Submit a shorter passage to have all of it analyzed. Request limits apply.

2

AI Analysis

The analysis service reviews writing patterns and returns an estimate. Those patterns can also occur in human writing.

3

Get Results

Read the model estimate and its explanation. The output does not prove authorship.

Features

Built for accuracy, designed for trust

Every feature is designed with precision and transparency in mind.

Lightning Fast

Paste a passage and request an analysis. Response time depends on service availability.

Interpreting Results

AI Text Detector can misclassify both human and AI writing. No verified accuracy or false-positive rate is published here. Treat the result as a prompt to review the text and its drafting history, not as proof of authorship.

Before You Submit

Text is sent to an external service for analysis. Do not submit confidential or sensitive material. Review the privacy policy before using the tool.

Detailed Reports

Go beyond a simple score. Read a document-level score, a confidence label, and a summary of writing patterns.

Integration Questions
