US prices (QuillBot Premium page and pricing FAQ, checked Oct 21, 2026). Premium has three billing options: $19.95 billed monthly, $39.95 billed every 3 months (about $13.31 a month) or $99.95 billed every 12 months ($8.33 a month). Over 12 months that is $239.40, $159.80 or $99.95, so yearly billing costs about 58% less than paying monthly, which matches the '58% off' label on the Premium page. Free limits: paraphraser and humanizer up to 100 words at a time, 2 paraphrasing modes (Standard and Fluency), summaries up to 1,200 words, limited AI detector access and no plagiarism checks. QuillBot uses regional pricing, so the price you see may be lower in some countries (from Vietnam we saw $4.17/mo billed annually). The Team plan has no public price; teams of 5 or more get a single invoice with a discount.
