About TextSight AI
TextSight is a free AI detector and AI humanizer that finds AI-sounding sentences (ChatGPT, Claude, Gemini, Llama), shows a Humanization Score, and helps you rewrite the flagged lines naturally. It provides sentence-level AI detection, per-sentence signals (perplexity, burstiness, vocabulary range), a Humanizer to rewrite up to 300 words, and a recheck workflow. No signup or card required for detection. Metrics: 1M+ texts analyzed and a measured 5.85% false-positive rate on their internal benchmark.
