QuillBot remains the paraphrasing tool most people mean when they say "just run it through QuillBot" — nine-plus rewrite modes, a grammar checker, a 6,000-word summarizer, and, more recently, an AI detector and humanizer bolted on. The free tier caps paraphrasing at 125 words per go, enough to sample but not to work with; Premium runs $19.95/month, or $8.33/month billed annually at $99.95/year. The academic-integrity grey zone hasn't gone away — a paraphraser aimed partly at students always draws that scrutiny — and Trustpilot carries a steady stream of billing complaints: failed cancellations, auto-renewed annual charges, and refund requests QuillBot says it only grants "if required by law." The AI detector, independently tested, catches roughly 70-80% of AI text and misfires on heavily-edited human writing. None of that dents its popularity with non-native English writers across ASEAN classrooms and offices.
What people say
Five months of charges totalling $99.75 that one Trustpilot reviewer says they never authorized — billing complaints like that are the most consistent negative thread around QuillBot in 2026, alongside refund requests QuillBot has reportedly denied outright, citing its own policy rather than any regulation. That's a real blemish on a tool most people otherwise like.
On the product itself, reviews are genuinely warm. QuillBot's paraphraser — now with nine-plus modes from Formal to Creative — plus its grammar checker, 6,000-word summarizer, and citation generator get consistent praise for speed and ease of use, especially from non-native English writers and students who make up a large share of its user base across ASEAN. The free plan (125 words per paraphrase, two modes) is genuinely usable as a sampler, not just a paywall teaser.
The newer AI detector and humanizer are more mixed. Independent testing puts detection accuracy around 70-80%, with false positives on heavily-edited human text and misses on AI output that's been manually revised — not something to lean on for anything high-stakes like an academic-integrity case. Paraphrasing tools in general still sit in a grey zone for students, regardless of QuillBot's own disclaimers.
Pricing is straightforward once you find it: $19.95/month, or $8.33/month on the annual plan ($99.95/year), with a 3-day money-back window. For casual rewriting and grammar cleanup it remains one of the more approachable AI writing tools around — just read the cancellation terms before subscribing.
