AI-Powered Document Intelligence
A complete solution for analyzing document quality, consistency, structure, readability, grammar, references, and anomalies — powered by Hidden Signal Engine™.
Grammar Intelligence
Comprehensive grammar detection powered by compromise NLP, wink-nlp POS tagging, and nspell spell checking.
- Article errors (a/an) — with phonetic exceptions
- Double negatives and wrong comparatives
- Tautologies — 20+ redundant phrase patterns
- Tense inconsistency across paragraphs
- Parallel structure in lists
- Subject-verb agreement (POS-based)
- Commonly confused words (fewer/less, affect/effect)
- Spelling errors with suggestions
- Sentence fragments and capitalization
Style Analysis
Identifies writing quality issues that weaken clarity and impact across formal documents.
- Passive voice detection (14 auxiliary + irregular participle patterns)
- Wordy phrase mapping — 25+ verbose constructions
- Clichés — 21 overused phrases
- Corporate buzzwords with plain-English alternatives
- Nominalizations — verb-buried-in-noun constructions
- Adverb overuse and weak existential constructions
- Sentence length monotony detection
- Filler words — very, really, basically, literally...
Readability Scoring
Measures document complexity using industry-standard formulas with accurate syllable counting.
- Flesch Reading Ease score
- Flesch-Kincaid Grade Level (Elementary → Professional)
- Complex word ratio (3+ syllable words)
- Average sentence and paragraph length
- Passive voice ratio
- Reading time estimate
- Grade-level labeling and improvement suggestions
Consistency Analysis
Detects naming, terminology, formatting, and spelling inconsistencies using TF-IDF and Jaro-Winkler matching.
- Name format inconsistency (Jaro-Winkler similarity ≥ 0.88)
- Unit system mixing (metric/imperial — distance, weight, temperature)
- British/American spelling variant conflicts
- TF-IDF key-term capitalization inconsistency
- Abbreviation format conflicts (US vs U.S., PhD vs Ph.D.)
- Number format inconsistency (words vs numerals)
Logic & Contradiction Detection
Catches logical conflicts that undermine document credibility.
- Polar-pair contradictions (increase vs decrease, success vs failure)
- Same metric with conflicting values
- Circular comparisons (A > B and B > A)
- Existence contradictions
- Scope overreach — absolute and superlative claims
- Authority claims without citations
- Hedge language density analysis
Numerical Intelligence
Statistical analysis of numbers, percentages, and table data using Z-score and IQR methods.
- Statistical outliers (Z-score ≥ 2.5σ)
- IQR fence detection
- Impossible percentages (> 100% or < 0%)
- Negative values in non-negative contexts
- Table column sum verification (±0.5% tolerance)
- Currency and unit anomalies
Document Structure Analysis
Evaluates heading hierarchy, section completeness, and document organization.
- Empty section detection
- Orphan heading detection
- Broken section numbering
- Missing introduction / conclusion signals
- Excessively long paragraphs (300+ words)
- Inconsistent list formatting
- Table structure validation
Reference Validation
Finds broken cross-references and validates all internal document links.
- Missing appendices, figures, and tables
- Broken section cross-references
- Undefined footnotes
- Forward references to non-existent sections
