Frequently Asked Questions
How does the humanizer work?
It uses a rule-based engine that runs entirely in your browser. It replaces known AI phrases with natural alternatives, adds contractions, breaks up unnaturally long compound sentences, removes excessive hedging, and humanizes robotic transition words — all without any external API.
Does this make text undetectable by AI detectors?
It significantly reduces signals that AI detectors look for, such as certain vocabulary patterns and sentence uniformity. However, no tool can guarantee 100% bypass of every detector. For best results, review the output and make a few personal edits yourself.
What's the difference between Light, Medium, and Aggressive intensity?
Light replaces only the most obvious AI phrases and adds basic contractions. Medium also varies sentence length and removes common hedging. Aggressive rewrites transitions, shortens formal phrasing, and applies all transforms — ideal for text that sounds very robotic.
Is my text sent to any server?
No. This tool has zero server-side processing. The entire humanizer engine runs as JavaScript in your browser. Nothing you type is ever transmitted.
Why is there a 5,000 character limit?
There is no PRO character gate. The 5,000-character marker is a performance guide for typical browsers; longer text can still be processed locally, but it may take longer.
What languages does it support?
Currently English only. The phrase database and contraction rules are built for English. Support for other languages may come in a future version.
