TextSight
Free AI detector and AI humanizer: find AI-sounding sentences, rewrite them and recheck in one place.
What is TextSight?
TextSight is a free AI detector and AI humanizer that shows which sentences in your text read as AI-written, then helps you rewrite them so they sound more natural. It checks text from ChatGPT, Claude, Gemini and Llama. Every scan gives you an AI probability, a 0-100 Humanization Score and a flag on each sentence.
What does TextSight do? Paste your text or upload a Word, PDF, .txt or .md file. TextSight marks the sentences that sound AI-written, you humanize only those lines, then you recheck the result in the same place. No copying text between an AI checker and a separate humanizer.
Is TextSight free? Yes. You get 3 free checks a day with no signup and no card. Paid plans start at $7.49 a month billed yearly, or $9.99 month to month.
How accurate is the TextSight AI detector? In our own benchmark of 1,180 human-written papers from 2018, TextSight wrongly flagged 5.85% of them. The data and method are public. Like every AI detector, it gives a probability, not proof.
How is TextSight different from GPTZero, ZeroGPT and Originality.ai? Most AI detectors stop at the score. TextSight carries on into the rewrite and the recheck, so it works as an alternative to GPTZero, ZeroGPT, Copyleaks or Originality.ai if you also want help with the flagged lines. It also works as an alternative to QuillBot or WriteHuman if you want to see your score before and after you rewrite.
Who is TextSight for? Students checking essays before they submit, writers and bloggers, SEO and marketing teams, and educators who want sentence-level evidence as one signal rather than a verdict.
Where can I use TextSight? On the web, in the free Chrome extension, and on iOS and Android. The AI Humanizer works in 50+ languages and the AI detector is optimized for English. Pro plans also include API access.
