9-Category AI Pattern Detection
Category 1
AI Vocabulary
Detects Tier 1 AI words (delve, tapestry, leverage, robust, seamless, etc.) with specific replacement suggestions.
Category 2
Formula Openers
Catches formulaic openings: "In today's world...", "Have you ever wondered...", significance inflation patterns.
Category 3
Formula Closers
Detects generic conclusions, conclusion-mirrors-intro, "the question remains" and similar wrap-up formulas.
Category 4
Hedging
Finds "could potentially", "might arguably", "seems to somewhat" — double qualifiers that weaken writing.
Category 5
Weak Transitions
Flags "Furthermore,", "Moreover,", "Additionally," — weak connector words that pad AI text.
Category 6
Chatbot Artifacts
Catches "I'd be happy to help", "Great question!", "As an AI" and similar chatbot-specific phrases.
Category 7
Sycophantic Patterns
Detects excessive praise, agreement, and validation patterns common in AI assistant output.
Category 8
Structural Issues
Analyzes paragraph uniformity, list overuse, "serves as" constructions, and vague attribution patterns.
Category 9
Style Markers
Checks contractions, sentence rhythm (CoV), length variation, and overall writing naturalness signals.
Iron law: facts, numbers, dates, and named entities are never changed. AI score 0-100 with before/after comparison.
