How does the AI Text Humanizer work?

It runs your text through an 8-pass LLM pipeline that systematically addresses different types of AI patterns: vocabulary, rhythm, sentence length variation, punctuation, transition words, and overall flow.

Is this better than other humanizers?

Most humanizers just swap words (utilize → use). This tool uses an LLM to rewrite with natural rhythm and structural variety. The difference shows in metrics like sentence length variance (CoV) and the absence of pattern clusters.

How long does humanization take?

Usually 15-45 seconds depending on text length. The 8-pass pipeline takes more time than instant tools, but produces significantly better results.

AI Text Humanizer

Paste AI-generated text. Get a humanized version using the 8-pass process — kill formula openings, vary sentence rhythm, strip Tier 1 vocabulary, cut hedging. Server-side LLM. Also available as a JSON API for agents and scripts.

Agent / script access:

POST https://helloandy.net/api/humanize
{"text": "your AI-generated text here (max 10,000 chars)"}

Returns JSON: humanized text, changes list, patterns_removed, rhythm_note, model used. Rate limited: 20 req/hour per IP. Responses take 3–8 seconds (free LLM tier).

The 8-Pass Humanizer Process

Pass 1

Kill Formulas

Remove formula openings ("In today's world…"), conclusion-mirrors-intro, significance inflation.

Pass 2

Strip Vocabulary

Replace 36 Tier 1 AI words: delve, tapestry, leverage, robust, seamless, groundbreaking, and 30 more.

Pass 3

Fix Grammar Patterns

Replace "serves as" → "is". Remove chatbot artifacts. Remove sycophantic openers.

Pass 4

Vary Rhythm

The most important pass. Vary sentence length deliberately. Target CoV > 0.4. Add fragments.

Pass 5

Cut Hedging

Remove "could potentially", "might arguably", "seems to somewhat". Pick one qualifier or none.

Pass 6

Vary Transitions

Replace "Furthermore,", "Moreover,", "Additionally," with direct pivots or no transition.

Pass 7

Add Specificity

Replace vague claims with specific ones where context allows. Flag with [CITATION NEEDED] where not.

Pass 8

Final Check

No Tier 1 vocabulary. No uniform sentence lengths. No generic conclusion. No mirrored intro/outro.

Iron law: facts, numbers, dates, and named entities are never changed.
