Paraphraser, grammar checker and summarizer in one app
Updated
QuillBot is an AI writing platform best known for its paraphrasing tool. It also includes a grammar checker, summarizer and citation generator.
You paste or type text into a tool, pick a mode such as a fluency or formal rewrite, and QuillBot returns revised wording that you accept sentence by sentence. The free tier limits input length. Premium raises limits and unlocks more modes and faster processing.
QuillBot is popular with students, researchers and non-native English writers who want to rephrase and polish text. Professionals use it for emails and reports.
The vendor pricing page blocked automated access. Third-party trackers report Premium at $19.95 per month, $39.95 per quarter or $99.95 per year (about $8.33 per month). A free plan is also available.
Alternatives include Rytr, which generates drafts from templates, TextCortex, which works across web apps with an AI assistant, and Copyleaks, which pairs plagiarism and AI detection with a writing assistant.
