Humanify Content Grader

Humanify Content Grader analyses your post content in real time and gives it a score from 0 to 100 based on how AI-generated it sounds. The lower the score, the more human your writing reads.

The plugin works directly inside the WordPress editor — in the block editor sidebar or as a meta box in the classic editor — so you can check and improve your writing before you hit publish.

What makes it different

Most SEO plugins focus on keyword density and meta tags. Humanify Content Grader focuses on something more important right now: whether your content reads like a human wrote it. AI search engines like ChatGPT, Perplexity, and Google AI Overviews are increasingly favouring content that sounds natural and authoritative. Robotic writing gets ignored.

What it detects

• AI buzzwords — delve, leverage, utilize, seamlessly, pivotal, holistic, synergy, etc.
• AI phrases — “it’s worth noting”, “in today’s rapidly evolving”, “in conclusion”, etc.
• Leftover AI artifacts — “I hope this helps”, “Certainly!”, “As an AI”, etc.
• Em dash overuse — one of the strongest AI writing signals
• Sentence length uniformity — AI tends to write in suspiciously even sentences
• Lack of contractions — AI writes more formally than humans
• Passive voice overuse
• Repetitive sentence openings
• Hedging language — “arguably”, “in many cases”, “broadly speaking”
• Redundant phrasing — repeated 3-word phrases across the content
• Weak AI-style conclusions — “in summary”, “as we have seen”, etc.
• Missing first-person voice
• No data points or statistics

How the score works

• 0–20: Sounds very human
• 21–40: Mostly natural
• 41–60: Some AI signals
• 61–80: Reads quite robotic
• 81–100: Very AI-like
