Each of the eight modes targets a different writing goal: Standard (balanced), Academic (formal scholarly tone), Creative (engaging style), Fluency (improved flow), Expand (adds supporting detail), Shorten (concise version), Formal (professional), and Humanize (makes AI-generated text sound naturally human-written).
Yes. QuillBot includes an AI content detector that identifies patterns typical of AI-generated text. The Humanize mode can then transform that content to read more naturally, which is useful for writers who draft with AI tools but want polished, authentic-sounding output.

The free plan limits paraphrasing to 125 words per request and the summarizer to 1,200 words per month. Only Standard and Fluency modes are available. Premium removes all word limits and unlocks all 8 modes, plagiarism checking, and advanced grammar features.
Grammarly excels at grammar correction and style suggestions but offers only basic sentence rephrasing.
