Frequently Asked Questions

How Does AI Writing Improvement Work?

Three simple steps to transform robotic AI text into natural, engaging content.

1

2

Choose Level & Tone

Pick your humanization intensity (1-5) and desired writing tone.

3

Why Does AI Text Sound Different?

AI models produce statistically likely text, which creates predictable patterns that human writing naturally avoids.

Understanding Humanization Levels

Five intensity levels from subtle polish to complete creative transformation.

Level 1

Light Polish

Fix obvious AI patterns while keeping 95% of the original intact.

Best for:Quick cleanup of mostly-good content
Meaning preserved:95%
Before

Furthermore, it is important to note that this technology has the potential to revolutionize the industry.

After

This technology could genuinely reshape how the industry works — and it's already starting to.

📝Level 2

Natural Rewrite

Moderate rewriting with mixed structures and killed buzzwords.

Best for:Blog posts, marketing copy, emails
Meaning preserved:80%
Before

In order to leverage innovative solutions, organizations must utilize comprehensive strategies.

After

To actually make new tools work, companies need clear, practical plans — not just buzzwords.

🔄Level 3

Thorough

Significant rewriting with personality, opinions, and rhetorical flair.

Best for:Thought leadership, opinion pieces
Meaning preserved:60%
Before

AI has become an integral part of modern business operations, facilitating growth and innovation across sectors.

After

Here's the thing about AI in business: it's not some future possibility. It's the reason your competitor just cut their costs by 30%.

💪Level 4

Aggressive

Heavy rewrite with extreme burstiness and zero AI patterns.

Best for:Personal essays, newsletters, social
Meaning preserved:40%
Before

The landscape of digital marketing continues to evolve, presenting both challenges and opportunities for businesses.

After

Digital marketing? It's a mess. A beautiful, chaotic, ever-shifting mess. And that's exactly why the companies paying attention are winning.

🎨Level 5

Creative Rewrite

Complete transformation — only facts survive. Magazine-feature quality.

Best for:Creative writing, storytelling, features
Meaning preserved:20%
Before

Remote work has transformed how teams collaborate, requiring new tools and methodologies to maintain productivity.

After

The office died on a Tuesday in March 2020. Nobody mourned it. What rose from its ashes — Slack pings at midnight, Zoom fatigue, the strange intimacy of seeing your boss's kitchen — changed everything.

How AI Detection Works

Understanding the science behind AI detection helps you write content that reads authentically.

What is Perplexity?

Perplexity measures how predictable each word is given the words before it. AI text tends to be highly predictable — it picks the most statistically likely next word. Human writing is less predictable because we make creative, surprising, and sometimes imperfect word choices.

AI
Low surprise
Human
High surprise

What is Burstiness?

Burstiness refers to the variation in sentence lengths. Humans naturally write in bursts — a short punchy sentence followed by a longer, flowing one. AI tends to produce uniform sentence lengths, creating a monotonous rhythm that trained readers can spot immediately.

Human
Varied

How Do AI Detectors Work?

Tools like GPTZero and Originality.ai analyse multiple statistical properties of text simultaneously. They look at word predictability (perplexity), sentence variation (burstiness), known AI phrases, structural patterns, and formality consistency. Our tool analyses these same dimensions to give you a detection score before and after improvement.

Tips for Better AI-Assisted Content

Use AI as a starting point, then apply these techniques to make it yours.

#1

Always edit AI output manually

Never publish raw AI text. Spend 10 minutes editing and you'll catch the patterns that make it sound artificial.

#2

Add your personal experiences

Drop in a story, a specific example, or your honest opinion. AI can't fake lived experience.

#3

Vary your sentence structure

Short sentence. Then a longer one that meanders a bit. Fragment. This creates natural rhythm.

#4

Use contractions naturally

Write "don't" instead of "do not", "it's" instead of "it is". That's how people actually talk.

#5

Replace generic with specific

Instead of "a popular tool", say "Figma" or "Notion". Specifics signal human knowledge.

#6

Read it aloud

If it sounds weird when you say it, it reads weird too. Your ear catches what your eye misses.

#7

Mix short and long paragraphs

One-sentence paragraphs are powerful. So are dense, detailed ones. Use both.

#8

Start strong — avoid generic openings

Skip "In today's fast-paced world" and start with a fact, a question, or a bold claim.
