Software Usage Instructions

Import content for detection: Select “Text Input” to directly paste articles, papers, copy, and other content, or select “Batch Files” to upload multiple text files. TXT, MD, CSV, JSON, XML, HTML, DOCX, and other formats are supported.
Select a detection mode:
- Comprehensive Detection: Performs a comprehensive analysis using indicators such as predictability, burstiness, common expressions, lexical diversity, and structural coherence.
- Quick Detection: Suitable for batch preliminary screening, with faster detection and more concise reports.
- Custom Detection: Allows you to adjust the weight of each indicator, the AI judgment threshold, and the confidence prompt threshold.
Configure detection parameters: Select the detection language, sensitivity, report detail level, and minimum paragraph word count. It is recommended to run a detection once with the default parameters first, then fine-tune them according to review needs.
Select detection methods: Enable predictability, burstiness, common AI expressions, lexical diversity, structural coherence, and hidden marker checks as needed.
Start detection: After entering the “Report Export” page, click “Start Detection”. The tool will generate AI probability, confidence, risk level, sub-metrics, and processing suggestions.
View and export reports: In text mode, you can download TXT, JSON, or CSV reports; in batch file mode, you can download a ZIP archive containing a summary report and detection reports for each file.

FAQ

A: The detection result is suitable as a supporting basis for judgment. AI text detection can be affected by text length, writing genre, degree of rewriting, and language style. It is recommended to make a comprehensive judgment together with manual review, original materials, and writing records.

A: Comprehensive Detection calls more indicators and generates a more complete report, making it suitable for formal review; Quick Detection focuses on statistical features and common expressions, making it suitable for preliminary screening of large volumes of text.

A: It is recommended to input text of more than 300 characters. The shorter the text, the fewer usable features there are, and the confidence may be lower. If it is a short sentence, title, or abstract, it is recommended to combine more context before detection.

A: Paragraph analysis can locate sections of text with more obvious AI characteristics, making it suitable for checking drafts that mix human-written content with AI-assisted content. Each paragraph shows the AI probability, confidence, and key issue prompts.

A: Batch detection generates the corresponding detection report based on the original file name. If duplicate file names are found, a number is added after the file name to distinguish them, and the summary report, CSV results, and individual file reports are packaged into a ZIP download.

A: Different tools use different training data, algorithm metrics, thresholds, and scoring methods, so results may vary. It is recommended to focus on confidence, paragraph results, and specific features rather than relying on a single percentage.
