Writers working in a second language who want grammar and fluency checks. Anyone who needs to restructure sentences without changing meaning. Students and early-career reporters building writing fluency. ## Editorial take QuillBot does one thing well: it rewrites text in multiple modes (Standard, Fluency, Formal, Creative, etc.) while preserving meaning. The free tier is genuinely usable for occasional paraphrasing. The concern is what sits behind it. Learneo (formerly Course Hero) acquired QuillBot in 2021 and now runs seven brands — Course Hero, CliffsNotes, LitCharts, LanguageTool, Scribbr, Symbolab, and QuillBot — all targeting the education and writing markets. In November 2025, QuillBot updated its privacy policy to store text inputs from browser extension users by default, with opt-out rather than opt-in consent. That's a meaningful change: everything you type through the extension now gets stored unless you actively disable it. QuillBot says it doesn't sell data and doesn't let third parties train AI on your inputs, but the shift from opt-in to opt-out storage is a trust signal worth noting. For journalists, the tool is useful for rephrasing — not for generating original reporting. Don't paste confidential source material into it. ## Best for / not for **Best for:** Rephrasing press releases or wire copy into your own voice. Grammar and fluency polishing, especially for non-native English writers. Restructuring sentences for clarity. Quick synonym suggestions. **Not for:** Original reporting or investigative writing — paraphrasing tools don't replace reporting. Anything involving confidential sources or sensitive information (text is processed on QuillBot servers). Plagiarism laundering — academic integrity tools can detect QuillBot output. ## Pricing - **Pricing:** Free plan with limited daily paraphrases and basic features.

If using the browser extension, check your privacy settings and opt out of text storage if available. Use the web interface for one-off paraphrasing rather than the always-on extension. For sensitive writing, use a local tool like LanguageTool's offline mode instead. ## Ownership & business - **Owner:** Learneo, Inc. (formerly Course Hero, Inc.), Redwood City, California.
