Key features
6Similarity Detection
It is claimed by the official that it adopts a multi-layered dynamic fingerprint comparison technology to identify text plagiarism, improper citation, content duplication and hidden plagiarism.
AIGC Detection
It identifies AI-generated content in texts. According to the official, it can locate AI-generated fragments throughout the full text and quantitatively mark their proportion and suspected probability.
AI Intelligent Evaluation
It scores the first draft and provides revision directions from five dimensions: the significance of the topic selection, writing arrangement, logical construction, professional competence, and academic norms.
Format Check & One-Click Formatting
It verifies the formats of the cover, abstract, table of contents, text body hierarchy and references against the university template, and supports automatic standardized formatting.
Intelligent Filtering
Allows setting a cutoff year for comparison, automatically identifies references and potential self-citations, and provides the similarity value after removal.
Multi-mode Submission
Supports single-file upload, text pasting, batch detection and self-built database comparison, and reports can be downloaded in PDF and HTML formats.
How to use Daya
- You can only enjoy the free detection quota purchased by your school by logging in with your Xuexitong or Mobile Library account, and you must complete the unit authentication before use.
- The official reminds that personal inspection reports have a retention period, and you need to download and save them in a timely manner after the inspection is completed.
- It is recommended to use DOCX instead of PDF, as the official note indicates that PDF may cause abnormal recognition of footnotes and endnotes, which will affect the results.
- The test results are for self-inspection purposes only and are for reference only.
- There may be differences from the school's official system, and the school's final confirmation shall prevail.
- The suspected proportion given by AIGC detection is a probabilistic annotation, and manual review is required before deciding how to modify the content.
- In addition, it should be specially noted that the output of AI detection is a "probability judgment" rather than a final conclusion: Misjudgments are not uncommon in scenarios such as short texts, dense professional terms, or content that has been deeply rewritten manually, and it is not recommended to use it as the sole basis for academic misconduct or content violations.
