TextGuard

TextGuard is a web-based application that assists users in verifying the originality of written content and improving its quality through a set of specialized tools. The platform focuses on three core functions: AI detection, plagiarism checking, and text humanization. For AI detection, TextGuard analyzes submitted text to determine whether it has been generated by artificial intelligence models, such as GPT-based systems. This is particularly useful for educators who need to identify AI-written assignments, for content managers who want to ensure authenticity in published materials, or for writers who wish to confirm that their work does not inadvertently resemble AI-generated patterns.

The plagiarism checker compares the submitted text against a database of academic papers, web pages, and other publicly available sources to highlight sections that match existing content. This feature is designed to help students, researchers, and professionals avoid unintentional duplication and maintain academic or professional integrity. The tool provides similarity reports that show matched passages along with source links, allowing users to review and revise problematic areas. Unlike basic copy-paste detection, the system can identify paraphrased or lightly modified content, giving a more thorough analysis. The text humanizer function addresses a growing need in the era of AI writing. It takes AI-generated or overly mechanical text and rewrites it to sound more natural, engaging, and human-like. This is not a simple synonym substitution; the tool re
