Humanizer: AI Pattern Detection & Voice Injection

Transform AI-generated text into human writing by detecting patterns and injecting authentic voice.

---

Before You Edit: Diagnostic Framework

Ask yourself these 3 questions BEFORE applying any patterns:

1. Voice Assessment

• Does this text have a distinct voice? Or is it neutral/corporate?
• What personality should come through? (witty, skeptical, conversational, authoritative)
• Are there opinions, or just facts? Human writing has stakes and perspective.

2. Pattern Prioritization

• Which 3-5 patterns dominate this text? (Don't fix everything at once)
• What's the writer's intent? (persuasive → keep some structure; casual → break all patterns)
• Should some "AI-isms" stay? (Formal technical docs may keep certain structures)

3. Rewrite Philosophy

• Am I removing patterns OR injecting personality? (Must do both)
• Does my rewrite sound like a specific human wrote it? (Not just "less AI")
• Have I varied sentence rhythm? (Short. Longer flowing sentences. Mix it up.)

The Core Principle: Sterile, voiceless writing is just as obvious as slop. Don't just remove bad patterns—add soul.

4. Pattern Detection Procedure (Domain-Specific)

Run these checks BEFORE editing:

Statistical Density Check:

• Count AI vocabulary words per 100 words: >3 = heavy AI signature
• Count em dashes per paragraph: >2 = structural tell
• Count "However" paragraph starts: >20% = AI transition overuse

Structural Signature Check:

• All paragraphs same length? = AI rhythm uniformity
• Every list has exactly 3 items? = rule of three addiction
• Conclusions use passive voice? = AI hedging pattern

Context-Specific Preservation:

• Academic: Keep formal structure, remove only vocabulary slop
• Technical: Preserve precision terminology, remove promotional language
• Marketing: Full humanization except brand voice requirements

Critical Anti-Patterns (NEVER Do This)

❌ Pattern #1: Mechanical Pattern Removal

Problem: Just deleting AI phrases without adding human voice produces sterile text.

❌ BAD EDIT:
"The framework serves as a testament to modern development practices."
→ "The framework is modern."

✅ GOOD EDIT:
"The framework serves as a testament to modern development practices."
→ "This framework gets it right. Clean APIs, sensible defaults, actual documentation."

Why this matters: Removing "testament to" makes it grammatically correct but soulless. The good edit has opinion, rhythm, and personality.

❌ Pattern #2: Over-Correction

Problem: Making every sentence "unpredictable" creates chaos, not humanity.

❌ BAD EDIT (too chaotic):
"Results. Interesting ones! The experiment? It generated code—lots of it.
3 million lines worth. Developers (some of them) were impressed!!!!"

✅ GOOD EDIT (controlled variety):
"I genuinely don't know how to feel about this. 3 million lines of code,
generated overnight. Half the dev community is losing their minds,
half are explaining why it doesn't count."

Why this matters: Human writing has rhythm variation, not random punctuation chaos.

❌ Pattern #3: Removing ALL Structure

Problem: Not all AI patterns are bad—some formal writing needs structure.

Context: Academic paper abstract

❌ BAD EDIT:
"Our study looked at machine learning. We found some stuff.
It's interesting. Check out our results."

✅ GOOD EDIT:
"This study examines machine learning approaches to code generation.
We evaluated three architectures and found that transformer-based
models outperformed RNNs by 23% on our benchmark."

Why this matters: Formal contexts need clarity over personality. Know your audience.

❌ Pattern #4: Batch-Replacing AI Words Without Context

Problem: Blindly replacing "delve" or "landscape" breaks legitimate usage.

Context: Computer vision paper

❌ BAD EDIT:
"Our model examines the feature landscape" → "Our model examines the feature terrain"

✅ GOOD EDIT:
"Our model examines the feature landscape" → "Our model analyzes feature space"
OR keep "landscape" if it's established terminology in CV papers

Why this matters: Not every AI word is wrong—check if it's domain-appropriate first. "Landscape" in data science ≠ "business landscape" slop.

Most Common AI Patterns (Quick Reference)

Content-Level Patterns

Undue Emphasis on Significance

• Words: stands as, serves as, testament to, pivotal, crucial, underscores, broader trends
• Fix: Remove inflated symbolism, state facts directly

Promotional Language

• Words: boasts, nestled, vibrant, rich heritage, breathtaking, stunning
• Fix: Replace adjectives with specific details

Vague Attributions

• Words: Industry reports, Observers note, Experts argue, Some critics
• Fix: Name specific sources or remove the claim

Language-Level Patterns

AI Vocabulary Words (post-2023 frequency spike)

• Words: delve, crucial, enhance, foster, garner, intricate, landscape (abstract), pivotal, showcase, tapestry (abstract), underscore
• Fix: Use plain synonyms or restructure

Copula Avoidance (avoiding "is/are")

• Pattern: "serves as", "stands as", "represents", "boasts", "features"
• Fix: Use simple "is/are/has"

Negative Parallelisms

• Pattern: "Not only... but...", "It's not just about X, it's Y"
• Fix: State directly without forced contrast

Style-Level Patterns

Em Dash Overuse

• Pattern: Multiple em dashes in one paragraph (—)
• Fix: Replace with commas, periods, or parentheses

Rule of Three Overuse

• Pattern: "innovation, inspiration, and industry insights"
• Fix: Break groups of three, vary list sizes

Title Case Headings

• Pattern: "Strategic Negotiations And Global Partnerships"
• Fix: Sentence case: "Strategic negotiations and global partnerships"

Humanization Strategy: When to Preserve vs Remove

The Decision Framework: Not all contexts need full humanization.

Context	Humanization Level	Remove Patterns	Inject Voice	Example Fix
Academic/Research	Low (10-20%)	Delete slop only (delve, testament to)	Minimal	Keep structure, remove AI vocabulary
Technical Docs	Medium (30-50%)	Remove promotional language, keep clarity	Light opinions	"This works well" → "This approach handles edge case X"
Blog/Marketing	High (70-90%)	Remove most AI tells	Strong voice	Full personality, distinct author presence
Social/Casual	Maximum (100%)	Delete all AI patterns	Maximum authenticity	Pure conversational, break all rules
Formal Business	Medium (40-60%)	Remove obvious slop, keep professionalism	Controlled confidence	"We believe this represents..." → "This delivers X"

Critical Non-Obvious AI Tells (beyond the common list):

• Paragraph-starting "However": AI overuses this transition (appears 3x more in GPT text)
• Passive voice in conclusions: "It can be concluded that..." (AI hedges at the end)
• Symmetric sentence structure: Every paragraph follows same length/rhythm pattern
• "Importantly" mid-sentence: AI uses this more than humans (statistical quirk)
• Abstract "landscape" metaphors: "the technology landscape", "the business landscape"

When to Load Full Pattern References

For comprehensive pattern catalogs, use mandatory loading:

MANDATORY - READ ENTIRE FILE:

references/content-patterns.md

when:

• Text contains 5+ promotional adjectives (stunning, breathtaking, vibrant, rich)
• Significance inflation detected ("serves as testament", "stands as pivotal")
• Need complete "symbolism removal" examples
• Do NOT load for casual blog posts or social media text

MANDATORY - READ ENTIRE FILE:

references/language-patterns.md

when:

• Text uses 8+ AI vocabulary words (delve, showcase, intricate, foster, garner)
• Heavy copula avoidance patterns ("serves as" instead of "is")
• Need elegant variation catalog for substitutions
• Do NOT load for technical documentation where precision matters

MANDATORY - READ ENTIRE FILE:

references/style-patterns.md

when:

• Text has 6+ em dashes in single paragraph
• Rule of three appears 4+ times
• Title case headings throughout document
• Do NOT load for academic papers (formatting may be required)

Never load references for simple opinion injection or rhythm fixes—handle with decision framework above.

Process

1. Read input text - Identify 3-5 dominant patterns
2. Apply diagnostic framework - Answer the 3 questions above
3. Make strategic edits - Fix patterns + inject voice simultaneously
4. Verify rhythm - Read aloud test (does it sound natural?)
5. Present result - Show rewritten text with brief summary if helpful

Quick Example

Before (AI-sounding):

The new software update serves as a testament to the company's commitment to innovation. Moreover, it provides a seamless, intuitive, and powerful user experience—ensuring that users can accomplish their goals efficiently. It's not just an update, it's a revolution in how we think about productivity.

After (Humanized):

The software update adds batch processing, keyboard shortcuts, and offline mode. Early beta feedback has been positive—most testers report finishing tasks faster.

What changed:

• Removed inflated symbolism ("serves as a testament")
• Removed AI vocabulary ("Moreover", "seamless, intuitive, powerful")
• Removed negative parallelism ("It's not just...it's...")
• Removed vague claims ("commitment to innovation")
• Added specific features (batch processing, shortcuts, offline)
• Added concrete evidence (beta feedback, faster completion)
• Kept neutral tone appropriate for feature announcement
