7 Check Areas

What JERVIS Checks in Your Copy

Every text is automatically extracted (excluding navigation, footer, cookie banners) and analyzed across 7 areas. This directly impacts your SEO scores und GEO citability.

✍ Spelling

Typos, incorrect spellings, missing or wrong special characters. Proper nouns, technical terms and intentional spellings are reliably filtered out.

📚 Grammar

Sentence structure, punctuation, case errors, tense shifts and agreement. Especially precise with complex sentence structures.

🔄 Consistency

Is the tone consistent across the entire website? JERVIS detects shifts — even between pages — and flags inconsistencies.

🎤 Tone of Voice

Does the tone match the brand? Is it inviting, professional, factual? JERVIS evaluates overall tone and detects style breaks within a page.

👁 Readability

Are sentences too long or convoluted? JERVIS measures readability and flags sentences that are hard for web readers to understand.

🔁 Redundancy

Is information repeated unnecessarily? JERVIS detects content repetition on the same page and suggests cuts.

⚠ Content Errors

Contradictions, outdated information, missing details. JERVIS checks whether the content is internally consistent and free of obvious errors.

Under the Hood

The 6-Layer Spelling Pipeline

Why JERVIS produces zero false alarms: every potential error passes through 6 filter layers before it gets reported.

1

Text Extraction

Visible body text is isolated. Navigation, footer, cookie banners and code blocks are removed.

2

Proper Noun Detection

Brand names, product names, personal names and technical terms are detected and excluded from checking.

3

Dictionary Check

Cross-reference against the dictionary. Compound words are correctly decomposed.

4

AI Context Analysis

AI checks remaining candidates in sentence context. Common homophones and similar traps.

5

Intent Filter

Intentional deviations are recognized: wordplay, dialect insertions, anglicisms and marketing jargon.

6

Confidence Threshold

Only errors with >95% confidence are reported. Uncertain cases are classified as "Info" instead of "Warning".

0%

False Positive Rate

Validated across 20 live websites with over 4,000 checked words. Every reported error is a real error — no noise, no guessing.
