What It Does

AI Detector Writer is a free AI content detection tool that analyzes written content to determine whether it was generated by AI (including GPT-3, GPT-3.5, GPT-4, GPT-5, OpenAI, and Bard) or written by a human. The tool leverages advanced natural language processing algorithms to scan text against a massive database of sources, identifying patterns in coherence, sentence structure, and language complexity that distinguish AI-generated content from human writing.

Key Features & Capabilities

• Unlimited Analysis: Scan content without word count limitations, supporting documents up to 300,000 characters • Batch File Upload: Process multiple files simultaneously for efficient bulk checking • Sentence-Level Highlighting: Each AI-generated sentence is distinguished with a gauge showing the proportion of AI contribution • Multi-Language Support: Accurately detects AI content across all major world languages • Automated Reports: Generate PDF reports for each detection to provide proof of content originality • Real-Time Results: Instant scanning with dynamic progress tracking • Multiple File Formats: Upload .txt, .md, .csv files or paste text directly

Who It's For

This tool serves educators verifying student work, content creators ensuring originality, businesses maintaining brand authenticity, and anyone needing to validate whether content is human-written or AI-generated. It's particularly valuable for quick verification workflows where speed and accuracy matter.

How It Works

Users simply visit the website, paste their text or upload a document, and the tool immediately scans the content. Results display the percentage breakdown of human-written versus AI-generated text, with highlighted sentences showing exactly which portions were likely produced by AI. The high-precision model is trained across all languages to deliver accurate, reliable detection results that help users refine their content before publishing or submission.
