Description
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

FAQ
-
Does this send my content to an external server?
-
No. All analysis runs entirely in your browser using JavaScript. Your content never leaves your site and no data is collected or transmitted.
-
Does it work with the classic editor?
-
Yes. The plugin supports both the WordPress block editor (Gutenberg) and the classic editor. In the classic editor it appears as a meta box below the content area.
-
What score should I aim for?
-
Aim for below 40. Under 20 is excellent. Over 60 means your content has significant AI signals that may affect how it reads to humans and AI-powered search engines.
-
Does a low score guarantee better rankings?
-
No. Humanify Content Grader is a writing quality aid, not an SEO guarantee. It helps you identify content that sounds robotic so you can improve it. Many other factors affect search rankings.
-
Can it be fooled?
-
Yes. If someone deliberately avoids all the detected patterns, they can score lower. The plugin is designed to catch common AI writing patterns, not to be a definitive detector.
-
Which editors does it support?
-
The block editor (Gutenberg) via a sidebar panel, and the classic editor via a meta box. It does not currently support page builders such as Elementor or Divi.
