QuillBot is a versatile AI-powered writing tool that helps users rephrase sentences, improve clarity, check grammar, detect plagiarism, summarize text, generate citations, and more. At its core, QuillBot excels as a paraphraser with multiple modes (like Standard, Fluency, Formal, Academic, Creative), an integrated grammar checker, and additional features like an AI humanizer, translator, summarizer, and even an AI detector. It’s widely used by students, bloggers, content creators, professionals, and educators to refine writing, avoid repetition, and produce polished, original content quickly and effectively.
Is QuillBot Free or Paid?
QuillBot follows a freemium model. The free version provides solid basic access to core tools like paraphrasing (limited to 125 words per use), grammar checking, summarization (up to ~2,500 words), and limited AI features—perfect for occasional or light use. Paid Premium subscriptions remove limits, unlock unlimited paraphrasing, advanced modes, faster processing, plagiarism checking, full AI humanizer access, and extras like higher image/AI generations, making them ideal for frequent writers, students with long papers, or professionals handling high-volume content.

Best Alternatives to QuillBot
Several strong competitors offer similar paraphrasing, grammar, and writing enhancement features. Here’s a comparison of top alternatives in 2026:
| Alternative Tool Name | Free or Paid | Key Feature | How it Compares to QuillBot |
|---|---|---|---|
| Grammarly | Freemium | Advanced grammar, tone detection, plagiarism checker, browser-wide integration | Deeper grammar/style suggestions and real-time corrections; stronger for professional polish but less focused on creative paraphrasing modes than QuillBot |
| Wordtune | Freemium | Sentence-level rewriting with tone/length adjustments, excellent for concise or expansive rewrites | Superior for natural-sounding rewrites and brevity/expansion; often feels more intuitive for quick edits but lacks QuillBot’s full suite (summarizer, plagiarism, AI detector) |
| Jasper AI | Paid | Long-form content generation, brand voice templates, marketing-focused writing | Great for full articles/blogs with templates; more content-creation oriented than QuillBot’s editing/paraphrasing emphasis |
| Writesonic | Freemium | AI article writer, SEO tools, chatbot integration | Strong for generating complete pieces and SEO optimization; broader content tools but paraphrasing feels less nuanced than QuillBot’s specialized modes |
| Humanize AI / Bypass Tools (e.g., WalterWrites) | Freemium/Paid | Advanced AI humanizing to evade detectors | Better for making AI text undetectable (e.g., passing Turnitin/GPTZero); specialized in humanization while QuillBot offers a more balanced writing assistant suite |
