Was This Written by AI? How to Detect and Humanize AI Content in 2025
With the rise of AI-generated content, one question keeps popping up: “Was this written by AI?” Whether you’re a teacher, employer, content manager, or just curious, detecting AI writing has become more important than ever. But don’t worry—there are powerful tools and strategies to help you find the answer, and better yet, ways to humanize AI content so it passes any test.
In this article, we’ll dive into everything you need to know about humanizing AI, using AI content detectors, and tools like Originality AI and Free AI detectors. Plus, we’ll compare the top rewriting tools and reveal the best option to make AI content look 100% human.
Humanize AI
If your content was written by an AI like ChatGPT or GPT-4, chances are it could be flagged by detection tools. The best way to avoid that? Humanize your AI-generated content. This involves rewriting the text to sound more natural, unpredictable, and emotional—just like a real person would write.
Tools like unGPT are specifically built to humanize AI content in seconds, making it indistinguishable from real human writing. Whether it’s an essay, email, or blog post, humanizing your text is essential to avoid detection.
AI Content Detector
An AI content detector scans your text to determine whether it was written by an AI model or a human. These detectors analyze sentence structure, vocabulary, tone, and predictability.
Popular AI content detectors in 2025 include:
- GPTZero
- Originality AI
- Copyleaks
- Writer AI Detector
These tools are commonly used by educators, publishers, and hiring teams. If you’re asking “Was this written by AI?” — these detectors are your first stop. But if you want to make your AI text pass those checks, you’ll need a humanizer tool, and unGPT does that better than anyone.
Humanize AI Text
To avoid getting flagged, you’ll need to humanize AI text. This means:
- Breaking up long, robotic sentences
- Adding emotional tone and personal touch
- Varying vocabulary
- Making the writing less predictable
Tools like QuillBot, Wordtune, and Grammarly can help a bit, but they don’t fully eliminate AI fingerprints. For serious results, use a tool like unGPT, which rewrites AI content deeply enough to bypass all major detectors.
Originality AI
Originality AI is one of the most trusted tools for detecting AI content. It’s frequently used in education and publishing to flag content that may not be human-written. It checks both AI and plagiarism in one scan.
If your content fails the Originality AI test, the best solution is to rewrite it using unGPT. It specifically optimizes your content to pass AI detection while keeping your message intact.
Free AI Detector
Several free AI detectors are available online. While they’re not always as accurate as paid versions, they can give you a good idea of whether your content might raise suspicion.
Top free tools include:
- GPTZero (basic version)
- Hugging Face Open Detector
- Content at Scale AI Checker
- Writer.com AI Detector
Use these tools to test your content, but if you need to guarantee a human feel, trust a reliable rewriter like unGPT to make your AI-generated content pass the test.
