How does this humanizer work without an API key?

It runs a pattern-based rewrite engine entirely in your browser. The tool swaps common AI-sounding phrases for natural alternatives, adds contractions, varies sentence lengths, and injects small stylistic touches based on the mode you pick. No external AI service is called, so nothing you paste leaves your device.

Will the output bypass every AI detector?

No tool can guarantee that. Detectors change constantly, and short or highly technical passages are hard to rewrite without changing meaning. The humanizer focuses on the patterns that most often flag AI writing — predictable rhythm, stock transitions, and missing contractions — so the result reads more naturally, but you should always review and edit the output yourself.
