TextSight

TextSight is an AI content detection and writing improvement platform built for students, freelance writers, educators, marketers, SEO teams and agencies. If you have ever stared at an AI detection score wondering what to do next, TextSight is designed to close that gap.

Paste text or upload a document and TextSight returns an AI detection score from 0 to 100, with the sentences that look machine-generated highlighted directly in your draft. Rather than handing you a single verdict, it explains the signals behind the score — repeated sentence rhythm, predictable word choice, filler transitions, uniform paragraph length — so you can actually see why a passage reads as AI.

The built-in humanizer then rewrites those flagged sentences to read naturally, and you can re-scan straight away to confirm the score has moved. This scan, rewrite and re-scan loop is the core workflow, and it is what separates TextSight from detectors that only give you a percentage and leave you guessing.

TextSight detects output from ChatGPT, Claude, Gemini and other large language models, so you are covered no matter which tool your draft came from. Alongside detection and humanization it includes grammar and readability checking, plagiarism checking, paraphrasing, summarization, translation, vocabulary improvement and word counting — 21+ tools in total, most of them usable without an account.

The free tier includes 20,000 AI detection characters per month, 3 document scans and 2,000 humanizer words, with no card required. Paid plans start at $9.99 per month and scale up to an Enterprise tier with API access, team seats and bulk scanning, so individuals and organizations alike can grow into the plan that fits.

TextSight runs in any browser and is also available as iOS and Android apps, so you can check and polish your writing wherever you work.
