AI Detector for X: Detect AI Tweets & Bot Replies | Humanizer AI

About

Instantly detect AI-generated tweets and bot replies on X (Twitter). This free Chrome extension adds an AI detection score to every post in your feed, so you always know what's written by humans and what's generated by ChatGPT, Claude, Gemini, or other AI tools.

AI bots are flooding X with low-quality replies and spam. Over 50% of internet traffic is now bots. This extension gives you back control over what you see.

HOW IT WORKS

The extension automatically scans tweets as you scroll through your feed on X. Each post gets a small, color-coded badge right next to the date:

  Green (0-30%): Likely written by a human
  Yellow (31-60%): Mixed signals, partially AI
  Red (61-100%): Likely AI-generated

Tweets that are too short for reliable detection get a gray "Too short" label so you're never misled.
