AI Text Checker: How to Detect and Humanize AI Content in 2025
In today’s world of AI-generated content, using a powerful AI text checker is critical. Whether you’re an educator, a publisher, or a student, knowing how to detect AI writing and humanize it can make all the difference.
This article will cover the best tools available and show you why unGPT is the ultimate solution if you don’t want to waste your time and money.
AI Detector
An AI detector is a tool designed to analyze text and determine if it was written by a human or generated by artificial intelligence models like GPT-4, Gemini, or Claude.
Popular AI detectors include:
- Turnitin AI detection
- GPTZero
- Winston AI
- Originality.ai
However, not all detectors are perfect, and many can mistakenly flag human-written text. That’s why you need an accurate AI text checker and a way to humanize AI text when necessary.
How to Check if Text Was Written by AI
Wondering how to check if text was written by AI? Here’s a simple process:
- Copy the text you want to analyze.
- Paste it into a trusted AI detector.
- Review the likelihood score (typically a percentage).
- If flagged as AI, use a humanizer to rewrite and recheck.
Remember: Some free detectors are unreliable. For accurate results, always use premium tools—or better yet, use unGPT, which not only checks but humanizes AI content automatically.
AI Detector Online
An AI detector online allows you to quickly scan documents without installing any software. Tools like:
- GPTZero
- Winston AI
- CopyLeaks
- Turnitin AI Detector
…are widely used. But if you want detection and humanization in one seamless process, unGPT is your best bet.
AI Text Humanizer
An AI text humanizer takes detected AI content and rewrites it to sound 100% human. This is crucial for:
- Students avoiding plagiarism accusations
- Writers publishing authentic articles
- Businesses maintaining credibility
unGPT is not just another paraphraser—it completely restructures AI-generated writing to sound naturally human while maintaining the original meaning.
Grammarly AI Detector
Did you know Grammarly AI detector now offers basic AI detection? While Grammarly is excellent for grammar and tone, its AI checker is limited compared to dedicated tools.
If you need something stronger to check and humanize AI text, Grammarly alone won’t be enough. That’s why users are switching to unGPT—the smarter alternative.
