How to Spot AI-Generated Content: Clues and Fair Checks

Knowing how to spot AI-generated content starts with reading for the job, not for the tool. Writing made with AI often sounds smooth but says little that fits your real situation, and the fair test is whether it holds up when you check it.

Terms like detector, large language model and synthetic text come up quickly in this topic. Our short guide to common AI terms defines each one in plain words.

What counts as AI-generated content?

AI-generated content is any writing, image or audio that a software tool produced, in whole or in part, from a request. It now shows up in vendor proposals, online reviews, guest posts and marketing emails. Some of it is honest help, and some is filler that nobody checked before sending.

For the basics, including when a business should label its own AI help, read our explainer on what AI-generated content is. This post covers the other side of the desk. It is about judging writing that someone hands to you. Pictures need their own checks, which we cover in how to tell if an image is AI-generated.

How to spot AI generated content in writing

You can often tell if text is AI generated by how little it commits to. It tends toward safe, general phrasing, tidy lists and confident claims with no source. It may also miss the small details that only someone who knows the job would include.

Look for a few patterns at once, since any one of them alone means little:

• Generic wording. Every point could apply to any company in any town.
• Unsourced confidence. Facts and figures arrive with no link, name or date.
• Wrong details. A proposal mentions services you never asked about.
• Even rhythm. Paragraphs run the same length and land on the same tidy note.

These clues fade over time. People edit AI drafts, and the tools keep improving. Plenty of careful human writers also write in tidy, even paragraphs. That is why a clue should lead to a question, never a verdict. So when people ask how to tell if something was written by AI, the honest answer is a mix of clues and checks.

Are AI detectors accurate enough to trust?

No, an AI content detector is not accurate enough to settle the question by itself. A detector scores how predictable the wording is and guesses whether a tool wrote it. Plain human writing can score as machine-made, and lightly edited AI text can pass as human.

An FTC final order (opens in a new tab) requires one detector seller to stop advertising accuracy unless it has competent and reliable evidence to back it up. The agency also alleged that the tool was built to sort only one narrow kind of writing well. So the honest answer on detector accuracy is that nobody should be accused of using AI on a score alone.

What are fairer ways to check?

Fairer checks look at the work itself and the person behind it. Ask for sources, check one key fact against the original, and ask for an earlier draft or notes. Then talk with the writer about the details. Someone who did the work can explain it easily.

These steps also catch the problem that matters more than authorship. A NIST transparency report (opens in a new tab) notes that authentic content can still be misleading, so writing a person typed can be wrong too. The business view is simple. What you want is writing that is true, useful and approved by a person, with AI help disclosed where readers would care. Our guide to AI marketing for small business covers the human check on your own content.

A kitchen remodeler uses an AI assistant to lay two cabinet suppliers' proposals side by side. It flags that one reads smoothly but cites no past jobs and lists finishes the remodeler never requested. The remodeler asks that supplier for photos of recent work and a reference to call. Only then does the remodeler decide which bid to accept.

Our Marketing Agent writes first drafts of posts and emails in your own voice from your own notes, so the details match your real business. Each of our six AI Agents is built around your rules, and this one is no different. A person edits and approves every word the Marketing Agent drafts and decides how to tell readers that AI helped.

Frequently asked questions

Can AI detect AI-generated content?

AI can guess, but it cannot reliably tell. Detector tools look for wording patterns that tools tend to produce, and those patterns also appear in plain human writing. Treat a detector result as a hint to check further, and confirm with sources, drafts and a conversation before you draw any conclusion.

Are AI detectors reliable?

No, AI detectors are not reliable enough to act on alone. They can flag careful human writing and miss AI text that someone edited. Use their scores, if at all, only as a starting point, and never accuse a vendor, writer or team member on that basis.

How can you tell if text is AI written?

Look for generic wording, confident claims with no sources and details that do not fit the real situation. Then check a fact, ask for a draft and talk with the writer. Those steps judge the writing fairly, without leaning on a detector score.
