Free AI HumanizerParaphrasing AI text means changing structure and wording while keeping meaning. Our engine applies curated mappings ("is able to" → "can", "utilize" → "use") from the TidyText project, extended with MIT-licensed AI-phrase lists.
Use Professional tone if you want paraphrase without informal slips; use Natural or Casual for full humanize mode. Everything runs in your browser. No API keys, no uploads, and no account. Paste AI copy from ChatGPT, Claude, Gemini, or Copilot, pick a tone, and click Humanize. The rewriter uses hand-checked phrase rules (MIT-licensed TidyText) to swap stiff AI wording, trim filler, and add natural contractions—without calling a paid LLM.
