Content Health
Overall text quality score: AI probability, readability, coherence, vocabulary richness, clarity and repetition. All metrics in one report; there is no comparison with the web.
Key facts
The content health check gives a text one 0–100 score from six statistical measures: naturalness, readability, vocabulary, coherence, clarity and absence of repetition. Free, no sign-up. It scores style; it is not a page SEO audit or a plagiarism check.

Content Health — Comprehensive Quality Assessment

- Click "Check Health" and wait for analysis
- Review overall score, radar and recommendations
FAQ
Who it is for and typical uses
- Checking neural-network text. “Naturalness” reflects the statistical probability of AI-written text; compare it with the AI detector.
- Editing an article. A low “clarity” score points to bureaucratic wording, and “originality” to phrase repetition inside the text.
- Comparing versions. Run the text before and after edits and check whether the overall score rose.
Honest limitations
- It is not a page SEO check. The tool ignores meta tags, links and keywords; use the site SEO audit and keyword density for that.
- “Originality” is not uniqueness. The measure counts repetition inside the text and does not match it against the internet.
- Readability is simplified. It measures how close the average sentence length is to 15 words, not a classic formula (Flesch and the like); there is a separate tool for that.
- Tone is not in the total. It is shown separately and does not change the score.
- Statistics, not a verdict. A short, technical or poetic text may score low; the weights are our own and conventional.

Scroll the table sideways
Where we are weaker: no keyphrase SEO guidance and no plagiarism check, the score is conventional, and readability uses sentence length only.
When to choose PromoPilot: When you want to rate a draft with one number and spot the weak point: repetition, formulaic phrasing, long sentences. For query-focused SEO optimisation, site checks and plagiarism you need other tools.
Checked on: . "—" means not confirmed on the official page; terms and prices change, so check the services' own sites.
