You’re scrolling through a LinkedIn post or maybe a recipe blog, and that nagging feeling hits you. Something about the flow feels... off. The sentences are too clean. The enthusiasm feels a bit hollow, like a customer service rep who’s been told they can't go home until they smile at ten more people. You find yourself asking: is this AI written? It's a weird time to be a reader. Honestly, it’s a weird time to be a human. We’ve reached a point where Large Language Models (LLMs) like GPT-4o, Claude 3.5, and Gemini don't just mimic us; they often write "better" than us—if your definition of better is "perfectly grammatical and devoid of any soul." But perfection is the giveaway. Humans are messy. We use weird metaphors. We trail off. AI doesn't usually do that unless you specifically tell it to, and even then, the "messiness" feels engineered.
The Smell Test: Why Your Gut Is Usually Right
Most people can spot a bot within three sentences, even if they can't explain why. It’s "the smell." AI tends to produce a "gray" texture of prose. It uses a rhythmic cadence that is almost too consistent. Think of it like a drum beat that never skips a beat or changes tempo. Humans naturally fluctuate. We might write a long, winding sentence that explores three different sub-ideas before finally coming to a point, and then we'll follow it up with: "See?"
AI struggles with that.
Common "Bot" Giveaways
One of the biggest red flags is the overuse of transition words. If you see "Furthermore," "Moreover," or "In conclusion" in a short blog post, your bot-radar should be pinging. Real people rarely talk like that unless they’re writing a formal legal brief or trying to hit a word count in a college freshman essay. Then there’s the "sandwich" structure. AI loves to tell you what it’s going to tell you, tell you the thing, and then tell you what it just told you. It’s incredibly repetitive.
Another thing? The "Safety First" tone. Because these models are trained with heavy guardrails, they tend to be incredibly balanced. They’ll rarely take a stand on a controversial topic without adding three paragraphs of nuance. While nuance is great, AI-nuance often feels like a corporate HR department wrote it to avoid a lawsuit.
The Myth of AI Detectors
Let’s talk about tools like GPTZero, Originality.ai, or Turnitin. You’ve probably seen them. You might have even used them. Here is the uncomfortable truth: they aren't foolproof. Not even close.
In 2023, OpenAI actually pulled its own AI classifier because the accuracy rate was abysmal. These detectors work on two main metrics: perplexity and burstiness. Perplexity measures how random the word choices are. Burstiness looks at sentence structure variation. If a piece of writing has low perplexity and low burstiness, the detector screams "AI!"
But what if you're just a really boring writer?
I've seen academic papers written by PhD students get flagged as 90% AI simply because the students were taught to write in a dry, predictable, "professional" style. Conversely, you can take a pure AI output, swap a few adjectives for slang, and break a couple of long sentences into fragments, and suddenly the detector says "100% Human." Relying on these tools for anything high-stakes—like firing an employee or failing a student—is a recipe for disaster.
Look for the "Hallucination" Haze
When you're trying to figure out is this AI written, look at the facts. AI doesn't "know" things; it predicts the next word in a sequence based on probability. This leads to hallucinations.
I remember asking an older model for a biography of a niche 19th-century poet. It gave me a beautiful, moving three-paragraph summary. It was poetic. It was detailed. It was also 100% fake. The poet existed, but the AI had "filled in the blanks" of his life with events that happened to other people.
Check the Specifics
- Dates and Names: Does the article mention a specific person but fail to link to their work?
- Fake Quotes: Does the quote sound like something a human would actually say, or does it sound like a "motivational poster" version of a quote?
- Generic Stats: Does it say "Recent studies show..." without actually naming the study or the year?
Humans usually link to their sources. We’re proud of our research. AI often treats "facts" as just another part of the prose flow.
The "Vibe" Shift in 2026
We're seeing a shift in how AI writes. The "As of my last knowledge update" era is over. Now, models can browse the web in real-time. This makes them much harder to catch. However, they still have a "personality" problem. Most AI models are trained to be helpful, harmless, and honest. This makes them come across as a bit of a "Teacher's Pet."
If an article feels like it’s trying a little too hard to be helpful—if it’s overly polite or uses phrases like "It is important to remember"—it’s likely a machine.
Think about how your favorite writers talk. They have "takes." They have biases. They might be a little grumpy or weirdly obsessed with a specific brand of coffee. AI doesn't have a "favorite" anything. It has a mathematical average of everyone’s favorites. That "average" feeling is the ultimate giveaway.
Reverse Engineering the Prompt
Sometimes the easiest way to tell is to imagine what the prompt was. If the article looks like it could be the result of a command like "Write a 1000-word article about the benefits of hiking with 5 subheadings," it probably is.
Real human content usually has a "Why." Why did the author write this now? Is there a personal anecdote? Does the author mention a specific trail they hiked last Tuesday where they forgot their water bottle and realized they’re not as fit as they thought?

AI can try to fake these stories, but they often feel "stock." They describe "the crisp mountain air" and "the feeling of accomplishment," but they miss the gritty, specific details—like the specific brand of blister band-aid that failed them at mile four.
How to Verify Authenticity Yourself
If you’re genuinely concerned about whether a piece of content is organic or synthetic, you can’t just rely on a website to tell you. You have to do a bit of detective work.
1. Check the Author's History
Does this person exist? Do they have a LinkedIn profile with actual connections, or is it a "dead" profile with a generated headshot? Look for a paper trail. Real experts have a history of talking about their subject across different platforms.
2. Look for Recent News
AI models, even with web access, often struggle to synthesize very recent, breaking news with the same nuance as a journalist who’s been on the ground. If an article mentions a localized event from two hours ago and provides original commentary, it’s probably human.
3. Test the Logic
AI is great at sounding logical while being completely nonsensical. Read a paragraph and then try to summarize the core argument. If the argument is just a circle of buzzwords that doesn't actually say anything new, you’ve found a bot.
4. The "Humor" Test
AI is notoriously bad at being funny. It can tell "jokes," but it struggles with wit, irony, and self-deprecation. If an article makes you genuinely laugh at a clever observation about human nature, a human likely wrote it.
The Future of "Is This AI Written?"
Soon, the answer might not matter as much. We’re entering an era of "Centaur Writing," where humans and AI collaborate so closely that the line disappears. A human might come up with the idea, outline the points, and have the AI "flesh it out," before the human goes back in to add the "soul."
Is that AI written? Or is it human-led?
The real danger isn't the AI itself, but the "Slop"—content generated in bulk with zero human oversight just to capture ad revenue. That's the stuff we need to get better at spotting.

Practical Steps to Navigate the AI Era
If you want to ensure you're consuming—or creating—authentic content, keep these points in mind:
- Demand Transparency: Support creators who are open about their use of AI. There’s no shame in using a tool, but there is shame in deception.
- Focus on Perspective: When writing yourself, lean into your "un-AI-able" traits. Share your failures, your weird hobbies, and your specific, non-obvious opinions.
- Cross-Reference: Never take a "fact" from a suspected AI source at face value. Google the specific claim.
- Value Curation: In a world of infinite content, the value moves from the person who can write to the person who can vet.
Stop looking for "perfect" content. Start looking for the cracks. The cracks are where the humans are.
Next Step: Take a look at the last three emails you sent. If they feel too formal, try deleting every "hope this finds you well" and "moreover." Write like you're talking to a friend at a bar. That’s how you beat the bots at their own game.
