Smodin.io's AI Content Detection tool employs advanced machine learning models to identify patterns in writing that indicate artificial generation. The system analyzes tone, phrasing, sentence variety, and flow patterns, drawing from an extensive training database to achieve high accuracy in distinguishing between human and AI-generated content.
The detection interface presents users with a straightforward workflow. Free users can analyze up to 5,000 characters per check, with the system displaying results through dual percentage bars showing AI content and human content ratios. The process supports multiple file formats including .docx, .doc, .pdf, .xls, and .csv uploads.
Analysis results highlight suspected machine-generated text sections, providing detailed feedback that enables users to understand specific areas of concern. This feature proves essential for protecting originality and avoiding misattribution issues, while also serving verification purposes for submitted work from students, employees, or freelancers.

Free users can analyze up to 5,000 characters per AI content detection check. The system displays results through dual percentage bars showing AI content and human content ratios, with highlighted sections indicating suspected machine-generated text.
The platform's plagiarism checker scans content against millions of online sources and academic databases, providing comprehensive verification against accidental copying. Free users can process up to 1,500 characters per scan, with language support covering 30+ options for testing.
The system offers two primary scanning modes: Web Search for standard verification and Text Comparison for side-by-side document analysis. Advanced options include Super Search functionality that performs deeper scans with extended processing time, and Google Scholar Search that focuses specifically on scholarly publications and academic sources.
Users can customize scanning parameters by adding specific URLs for inclusion or excluding particular sites from comparison. The scanning process delivers rapid results for standard checks, with comprehensive scans requiring additional processing time but providing more thorough analysis.
