TextSight

What is TextSight

TextSight is an AI detector and AI humanizer that scores any text from 0 to 100 for AI-generated writing, highlights the exact sentences that read as machine-written, and rewrites them so they sound human. It bundles 21+ writing tools — plagiarism checking, grammar, readability, paraphrasing, summarization and translation — into one place, so you can check a draft and fix it without switching between five different sites.

How to use TextSight

1. Paste your text — Drop in a paragraph, upload a .docx or .pdf, scan a URL, or feed a batch via API.
2. Analyze — The v4 model runs five classifiers on every sentence: perplexity, burstiness, stylometry, embeddings, and a transformer head.
3. Act — Get an Authenticity Score plus Rewrite Suggestions. Apply them one-by-one, or run the full AI Rewriter.

Features of TextSight

• Sentence-by-sentence AI highlighting — Every sentence gets its own confidence score, color-coded right inside the text.
• Authenticity Score (0–100) — A calibrated metric that rolls up sentence-level scores into a single actionable number.
• Rewrite Suggestions — One-click rewrites for every flagged sentence that keep the meaning but lose the AI tell.
• Model attribution — Fingerprints stylistic patterns to identify ChatGPT, Claude, Gemini, or Llama 3.
• One-click AI Rewriter — Choose a tone (conversational, professional, academic, blog, email) and get a rewrite that reads like you.
• 20 free AI writing tools — Detect (5), Write (5), Refine (5), and Research (5) tools in one workspace.
• Privacy by default — Scans save to your history so you can reopen them, and one switch turns that off. GDPR-aware, and text is never sold.
• Multi-format input — Paste text, upload .docx or .pdf, scan a URL, or use the API for batch processing.
• 50+ languages supported for the rewriter (detector is English-only).

FAQ

How accurate is TextSight.ai at detecting AI content? Tested on an internal benchmark across major AI writing tools including ChatGPT (GPT-3.5, GPT-4, GPT-4o), Claude, Gemini, and Llama 3. Any single verdict is treated as one signal. No detector is 100% accurate; results may vary by content type, writing style, model version, and editing level.

What is the Authenticity Score? A 0-100 metric that tells you how "human" your text sounds. A higher score means your content reads more naturally. Computed on every scan and every AI Rewriter rewrite so you can track your draft's progress.

Is there a free plan available? Yes. The free plan gives 20,000 characters of detection a month (up to 5,000 per scan), AI detection, authenticity scoring, and 2,000 rewriter words a month. No credit card required.
