Document Intelligence
Advanced AI semantic review leads every scan — detecting contradictions, grammar issues, scope overreach, anomalies, and hidden patterns. The Hidden Signal Engine™ runs deterministic rule checks as a parallel verifier, catching what AI may miss.

Advanced AI
AI-Powered Document Intelligence
Go beyond pattern matching. Advanced AI semantic review detects what rules cannot — context-aware grammar analysis, contradiction detection, scope assessment, and intelligent writing recommendations.
AI Grammar & Spelling
Context-aware grammar analysis detects subject-verb agreement, article misuse, spelling errors, and sentence structure issues that pattern-matching misses.
ProContradiction Detection
Semantic reasoning identifies statements that contradict each other — even across distant paragraphs — including conflicting facts, dates, and claims.
ProScope Overreach Analysis
Detects conclusions that exceed the evidence presented. Flags unsupported assertions and overstated claims before they undermine document credibility.
ProTerminology Consistency
Identifies inconsistent naming of the same concept across the document — ensuring professional clarity and reducing reader confusion.
ProRisk & Authority Signals
Surfaces hedge language, unverified authority claims, and compound risk signals that weaken document authority and invite challenge.
ProIntelligent Corrections
Every AI finding includes a concise suggested fix and a detailed correction with context — actionable guidance, not just detection.
ProA Smarter Way to Understand Documents
Hidden In Numbers helps uncover insights that traditional document reviews often miss. Powered by Hidden Signal Engine™, our platform combines grammar intelligence, consistency verification, anomaly detection, readability analysis, and document quality assessment into a single experience.
Capabilities
Everything You Need for Document Intelligence
AI-Powered Document Intelligence combines seven specialized engines into one unified analysis pipeline.
Grammar & Writing Quality
Detects grammar mistakes, article errors, tautologies, tense inconsistencies, parallel structure violations, and spelling issues.
Logic & Contradiction Detection
Identifies conflicting statements, opposing claims about the same metric, circular comparisons, and existence contradictions.
Reference Validation
Finds broken cross-references, missing appendices, absent figures, and dangling citations throughout the document.
Document Structure Analysis
Analyzes heading hierarchy, detects empty sections, orphan headings, broken numbering, and missing introductions or conclusions.
Consistency Verification
Flags name format mixing, unit system conflicts, spelling variant inconsistencies, and terminology drift across sections.
Readability Scoring
Calculates Flesch-Kincaid grade level, complex word ratio, passive voice density, and average sentence length.
Statistical Anomaly Detection
Uses Z-score and IQR analysis to surface numerical outliers, impossible percentages, and table summation errors.
Document Health Scoring
Generates an 8-dimension health score covering grammar, readability, consistency, logic, structure, style, and numerical integrity.
Powered by Hidden Signal Engine™
Hidden Signal Engine™ is our proprietary document intelligence technology that combines deterministic rules, linguistic analysis, statistical validation, consistency verification, readability assessment, and document quality scoring.
Unlike traditional spell checkers and document scanners, Hidden Signal Engine™ evaluates the overall health, quality, structure, and integrity of a document.
