How to Tell If Text Was Written by AI: A Practical Guide

In a world where AI-generated content is becoming increasingly hard to spot, being able to tell whether a piece of text was written by a human or machine is more important than ever. Whether you're an educator, content creator, or just curious, this guide will walk you through how to identify AI-written text — and why it matters.

Why It’s Getting Harder to Tell

AI tools like ChatGPT and Claude have become remarkably sophisticated. They produce clean, grammatically correct sentences, adapt tone and structure to prompts, and even mimic human mistakes. This makes it incredibly hard to detect AI with the naked eye, especially for non-experts.

Red Flags in AI-Generated Text

• Overly Formal or Neutral Tone: AI often writes in a generic, polished tone — even when the topic calls for emotion or personality.
• Repetition and Redundancy: You might notice phrases repeated or the same idea reworded unnecessarily. AI tends to play it safe by circling back.
• Lack of Specificity: AI-generated text can be vague. It often uses placeholders or generalities rather than concrete examples or facts.
• Strange Transitions: Look for awkward or robotic shifts between paragraphs — these can feel mechanical or out of place.
• No Real Point of View: Even when answering a question, AI often avoids taking a clear stance or offering nuanced opinion.

The Problem With Manual Detection

While these clues are useful, they aren’t foolproof. AI models are constantly improving, and some human writers (especially non-native speakers or very formal professionals) can exhibit similar traits. That’s where automated tools come in.
