TextSight

TextSight is an AI detector and humanizer that shows you WHICH sentences read as AI-generated — not just a percentage. Paste text or upload a DOCX/PDF, and get a 0–100 Authenticity Score in seconds, with the specific sentences that read as AI highlighted and explained: sentence rhythm, vocabulary patterns, structure. The built-in AI Humanizer rewrites flagged sentences so they sound natural while keeping your meaning. Rescan immediately to verify the improvement — a complete detect → fix → verify workflow in one tool. TextSight detects output from ChatGPT, Claude, and Gemini, including mixed human-and-AI drafts, and runs grammar, readability, and plagiarism checks in the same scan. The workspace also includes 20 free writing tools: paraphraser, summarizer, citation generator (APA, MLA, Chicago, Harvard, IEEE), translator, word counter, text compare, and readability checker. What makes TextSight different is honesty about accuracy. No detector is perfect, and we don't claim "99% accuracy" like much of the market — we publish our real benchmark methodology, so students, teachers, and content teams know exactly what a score means. Free tier: daily scans with no signup for your first check. Paid plans are flat-rate with generous word limits, file uploads, scan history, and REST API access. Built by a solo founder in India.
