How to Spot AI Writing: 5 Signs Your Content Wasn't Written by a Human

How to Spot AI Writing — 5 Clear Signs for Writers

AI writing is everywhere—social media, blogs, emails—you’re probably seeing it more than you think. That perfectly polished email, the product review that sounds oddly formal, or a Reddit post with a strangely corporate vibe might all be AI-generated by tools like ChatGPT, Gemini, or Claude.

These AI-generated texts often hit every point precisely, maintaining an unnaturally upbeat tone. But AI detectors aren’t foolproof, and subtle giveaways can slip past automated checks. The good news? You don’t need fancy tools to spot AI writing. The clues are in the text itself.

The Right Way to Use AI in Writing

Using AI to improve your writing isn’t wrong. AI tools are great for grammar checks, suggesting word choices, and adjusting tone—especially if English isn’t your first language. They help brainstorm ideas, overcome writer’s block, or polish drafts.

The key is to use AI to support your voice and knowledge, not replace it. Problems arise when people copy-paste AI output without adding insight or personality. That’s when the signs below show up.

1. Spot the "Have you ever..." Openings

AI writing often starts with the same hooks: “Have you ever wondered...”, “Are you struggling with...”, or “What if I told you...” These formulas come from patterns AI learned in marketing and blog posts.

Real writers mix it up. They might jump straight into a story, share a unique fact, or get right to the point without the usual setup. If you see multiple rhetorical questions or generic openings that could fit any topic, you’re likely reading AI-generated content.

2. Everything Sounds Weirdly Generic

Watch for vague phrases like “many studies show”, “experts agree”, or “a recent survey found” without specific sources. AI tends to avoid naming actual brands, people, or statistics.

Human writers include concrete details and references to real events or experiences. If content lacks those specifics, it’s a strong sign AI wrote it.

3. It Reads Like a Press Release

AI content often feels impressive but hollow. Expect to see overused business jargon like “innovative”, “revolutionary”, or “game-changing” thrown in without clear explanations.

Human experts explain why something works or admit when it’s difficult. If the writing seems designed to impress rather than inform, AI probably had a big hand in it.

4. The Tone Is Relentlessly Upbeat

AI maintains a smooth, enthusiastic tone from start to finish. Problems are always simple, solutions clear, and controversy absent.

Real writing varies. It includes frustration, tangents, doubt, or strong opinions. If the voice never wavers from positive and polished, it’s likely AI-generated.

5. It’s Missing the Real-World Mess

AI can explain basics well but misses practical complications. Advice sounds textbook-perfect but lacks the “yeah, but in reality...” moments that come from real experience.

Human writers add caveats, mention common pitfalls, and acknowledge when advice doesn’t fit every situation. If the content treats complex topics as simple, that’s a red flag.

Don’t Blame the Em Dash

People often point to em dashes as proof of AI writing. That’s unfair. Writers have used em dashes for centuries to add drama, pauses, or extra thoughts.

The real issue is how AI uses them—often incorrectly. AI may insert em dashes where a semicolon fits better or use them to create false drama in dull sentences. Real writers use em dashes purposefully. Before blaming AI, check if those dashes actually add meaning or just clutter the text.

For writers curious about sharpening their skills with AI tools, exploring targeted AI writing courses can be a smart move.
