Frequently asked questions
Is WriteKit really free?
Yes. All nine tools are completely free to use with up to 10 transformations per day. No sign-up, no credit card.
How does the Text Humanizer work?
Our humanizer rewrites AI-generated text to remove common AI patterns — overused words, uniform sentence length, and robotic phrasing. Choose from three levels: light touch, standard, or heavy rewrite.
What's the difference between the Humanizer and Paraphraser?
The Humanizer specifically targets AI writing patterns to make text sound human. The Paraphraser rewrites any text with different words and structure — useful for finding fresh wording or avoiding repetition, regardless of whether the source is AI-generated.
Is my text stored or shared?
No. Your text is processed in real-time and never saved to any database. We don't log or store the content you submit.
What AI model powers WriteKit?
WriteKit uses advanced large language models optimized for each specific writing task. Each tool has a custom-tuned prompt for best results.
Can I use WriteKit for professional work?
Absolutely. WriteKit is used by students, professionals, content creators, and anyone who writes. The email writer and grammar fixer are especially popular for business use.
