What is TextSight AI?
TextSight.ai is an AI detection, authenticity scoring, and rewriting platform built to help users understand how human or AI-like their writing appears. The platform scans text sentence by sentence and highlights which parts look AI-generated, mixed or edited, or human-written. TextSight.ai provides an Authenticity Score from 0 to 100 so users can see not only whether content may be flagged, but also which sentences need attention. Its v4 model is designed for calibrated AI detection with low false positives and can identify writing patterns associated with ChatGPT, Claude, Gemini, Llama 3, and other AI tools. Users can paste text, scan URLs, upload files, or use API workflows for higher-volume detection. The AI Rewriter provides one-click sentence-level rewrites that preserve meaning, facts, citations, names, and numbers while changing rhythm, phrasing, repetition, and other AI tells. TextSight.ai supports multiple tones, including conversational, professional, academic, blog, and email. The platform includes model attribution, perplexity signals, burstiness signals, sentence variance, vocabulary range, readability grading, scan history, and privacy controls. Its 20 free AI writing tools span detection, writing, refinement, and research, including an AI Detector, Hallucination Detector, AI Image Detector, AI Voice Detector, Plagiarism Checker, Paraphraser, Summarizer, Translator, Grammar Checker, Fact Checker, Citation Generator, PDF Summarizer, and YouTube Summarizer. TextSight.ai is designed for students checking essays, writers protecting their voice, SEO teams auditing content libraries, and educators reviewing writing with sentence-level evidence. By combining AI detection, Authenticity Scores, rewrite suggestions, model fingerprinting, multilingual support, file uploads, URL scans, API access, and a full writing toolset, TextSight.ai helps users detect, understand, and improve AI-assisted content.
