Methods to inform if one thing is written by AI: 5 indicators to search for
Recognizing AI-generated content material isn’t at all times simple, however there are some potential indicators to observe for when studying a bit of content material. Keep in mind, simply because content material meets a number of standards doesn’t verify that somebody created it with an AI software. (Watch out with accusations!)
Trait | Human-written | AI-written |
Tone and voice | Distinct, assorted, or emotionally nuanced. Could present bias, humor, or character | Typically impartial, flat, or overly enthusiastic (particularly when prompted for “inspirational” or “daring”) |
Examples and specifics | References real-life experiences, quotes, stats, anecdotes, or {industry} data | Hardly ever contains precise examples until explicitly prompted, tends to generalize |
Construction | Might be inventive, inconsistent, or narrative-driven relying on the author | Extremely structured, templated, and overly “clear”, particularly in listicles or how-to codecs |
Transitions | Contextually easy or stylistically assorted (even when imperfect) | Typically abrupt or unnatural, could change tone or matter too shortly |
Repetition | Avoids redundancy (until intentional for emphasis) | Could restate the identical level a number of occasions in numerous phrases to fill house or full an inventory |
Phrasing quirks | Consists of cultural references, idioms, sarcasm, or humor. Even typos or tangents | Makes use of formal or overly polished language |
1. It’s surface-level and imprecise
Most notably, one of many frequent themes of AI-written content material is that it’s high-level and doesn’t discover the subject past surface-level explanations.
If the content material considerations a enterprise idea, it usually makes use of numerous fluffy enterprise jargon (e.g., bandwidth, leverage, synergy). It may also present fundamental recommendation with out particular info or steps to again it up. Whereas the recommendation would possibly make sense, it is probably not tangible or relevant to the reader.
Once I requested ChatGPT how one can foster workforce alignment, right here’s what it got here again with:
Supply: ChatGPT
Though this recommendation technically solutions my query, it’s so imprecise that I’ve follow-up questions to assist me apply it, together with:
- How can I set up clear and measurable targets?
- How usually ought to I conduct a “common” workforce assembly to align priorities?

Fast tip: Ask your self, does this content material educate me one thing new or simply state the apparent in fancy language?
2. It repeats concepts with out including depth
Many prompts present outputs in numbered or bullet-point lists, which might typically appear repetitive.
I prompted ChatGPT with: What are 10 advantages of a wholesome work-life stability?
Supply: ChatGPT
All of those factors is perhaps true, however “elevated productiveness” and “enhanced focus and focus” are related factors worded in a different way, and each descriptions begin with “taking breaks…” This duplication is very noticeable when it tries to attain a numbered listing.
3. The tone is both off or utterly lacking
Content material that feels flat or mechanical could also be AI-generated. In lots of instances, with no particular immediate indicating in any other case, AI-generated content material is dry and flat. It doesn’t essentially learn with an outlined tone or character.
AI fashions sometimes return responses like this when requested: Write a paragraph about the advantages of AI for data employees.
Supply: ChatGPT
A paragraph about the advantages of AI data employees with a distinguishable tone and voice would possibly as a substitute sound one thing like:
Information employees can reap the quite a few advantages of AI instruments within the office.

Supply: ChatGPT
Phrases like “the beacon illuminating the trail,” “transcend the boundaries of time and house,” and “labyrinth of knowledge overload” might sound too intense or displaced.

On the time of writing, most superior and widespread instruments have a data cutoff round mid-2024—early 2025, which means they will’t produce correct particulars past that.
Actuality verify: If the content material confidently references a 2025 replace or breaking information, double-check the supply. AI won’t be maintaining.
5. It lacks private perception or real-world context
AI-generated content material usually reads like a well-structured textbook abstract: technically appropriate, however lacking the messy, nuanced particulars that come from actual expertise. It hardly ever affords authentic takes, industry-specific nuance, or situational context. You would possibly discover that the content material avoids referencing actual firms, instruments, quotes, or person eventualities. It floats in generalities.
For instance, a human-written article about distant work would possibly point out what it’s like managing conferences throughout time zones, or cite a selected communication breakdown that sparked a coverage change. AI content material, in contrast, would possibly merely say, “Distant work requires sturdy communication expertise.”
It’s not that the assertion is mistaken; it’s simply unhelpful. There’s no specificity, no story, no lived perspective.
Fast guidelines: Different frequent indicators of AI-generated content material
- Overuse of AI-typical phrases like “realm”, “in in the present day’s world of”, “panorama of”

- Is the tone oddly impartial?
2. Take note of overused phrases
As mentioned earlier than, repetitive phrases, phrases, and sentences are probably apparent indicators of AI-generated content material. Machine studying fashions observe patterns and replicate them, which suggests they’re comparatively good at repeating the identical info (or a sample).
