How to Spot AI Writing in 60 Seconds: A Step-by-Step Guide (2026)
How to spot AI writing fast: a step-by-step manual checklist — the words, the punctuation, the structure tells — with a live tool to confirm what you find.
TL;DR: Read the first three sentences, then the last two. Count prefab openers, hedged claims, and missing specifics. Two or more confirmed tells: run the text through the detector for a factor-by-factor verdict. Total time: about a minute.
The 60-second method at a glance
- Skim the opening (10s)
- Count vocabulary tells (15s)
- Check the punctuation habits (10s)
- Test for substance (15s)
- Verify (10s)
Step 1 — Substance: does it say anything?
Ask the only question that matters: what do I know now that I didn’t know before? Slop’s answer is nothing. Look for the absence of dates, prices, names, measurements, or first-person failures. If every sentence could appear in a hundred other articles, your suspicion is already 80% confirmed.
Step 2 — Vocabulary: the giveaway words
Scan for the heavy hitters — delve, tapestry, testament, pivotal, realm, seamless. You are not counting every hit; you are noticing whether the text dresses up simple statements. “The results were important” written as “the results were pivotal in navigating the competitive landscape” is the whole disease in one phrase.
Step 3 — Clichés: the empty-phrase count
The prefab openers are the fastest tell on the page: “in today’s rapidly evolving world”, “it’s important to note that”, “whether you’re a beginner or a pro”. One is a style choice. Two-plus is a template.
Step 4 — Structure: the rhythm test
Read one paragraph aloud. Do the sentences all breathe for the same amount of time? Generated prose loves medium-length sentences in unbroken formation. Count em dashes: three in a short paragraph of plain prose is a flag. Look for rule-of-three lists — “faster, smarter, and more secure” — stacked in every section.
Step 5 — Diversity and voice: does anyone live here?
The last check is for a person: a specific complaint, an odd detail, an opinion that could lose an argument. Slop has no stakes. If the text takes no position you could disagree with, that is the position — safely generated.
Putting it together: two or more, not one
Humans use em dashes. Humans write listicles. The conviction standard is two independent signals, ideally from different steps. Vocabulary cliché + no specifics: slop. One em dash + a personal anecdote with a date in it: probably a human having fun.
Do it automatically in one paste
The manual method makes you faster at noticing; the detector makes you precise. Paste the text and you get a 0–100 score, a five-factor breakdown, and every matched phrase highlighted — so your final call is a check, not a guess.
