Our verdict
QuillBot has evolved into a full writing suite, not just a paraphraser. Premium unlocks unlimited modes (plus Custom), advanced grammar, full AI detection and humanization, custom summaries, and a 25,000‑word/month plagiarism checker. The Free tier is generous for trying basics but has hard caps: 125‑word paraphrases, two modes, 1,200‑word summaries, limited AI detection, and a tiny AI Humanizer allowance; no plagiarism checks. Pricing is excellent if you prepay annually ($99.95/yr ≈ $8.33/mo) but relatively poor month‑to‑month ($19.95). A short‑term prepaid option at $39.95 suits exam seasons. The new Team Plan adds usage metrics, user management, centralized billing, and priority assistance for organizations. Apps and extensions span Chrome, Edge, Safari, Windows, macOS, Android, iOS, plus Microsoft Word and Google Docs. There’s no public developer API listed, and limits can vary by platform. Overall, QuillBot is compelling value on annual billing for students and creators who need paraphrasing, detection, citations, and translation in one place.
