After analyzing 5,000+ AI-generated articles in early 2026, I noticed the same 300 words and phrases appear over and over.

How to Spot AI-Generated Content Fast

8-point checklist:

Opens with "In today's..." or similar?
3+ buzzwords in first 200 words?
Every sentence same length?
Paragraphs all start with a transition word?
Any concrete numbers, names, dates?
Uses "delve," "leverage," or "robust" more than once?
Personal voice, opinion, or anecdote present?
Would you read this aloud without cringing?

If you answered yes to 4+ of the first 6 and no to 7 and 8, the content needs more human editing.

Common Mistakes

Mistake #1: The Thesaurus Trap
Replacing "leverage" with "utilize" doesn't help—both are AI-coded. Use plain language.

Mistake #2: Overcompensating with Slang
Adding "bruh," "no cap," or "fr fr" makes it worse.

Mistake #3: Adding Typos on Purpose
"teh" instead of "the" doesn't fool readers.

The Bottom Line

Words aren't inherently AI or human—patterns are. A single "delve" doesn't make text machine-written. But clusters of these phrases, formulaic sentence structures, and lack of specific details do.

The best AI-assisted writing in 2026: Use AI to brainstorm and structure. Write the final draft yourself with specific examples, real data, and your own voice. Tools help with the first 50% of writing. The last 50%—where trust and originality live—is still a human job.
