QuillBot

QuillBot is a paraphrase-first writing toolkit: its Paraphraser rewrites sentences and passages in different modes — Standard, Fluency, Formal, Creative and more — while the same subscription adds a grammar checker, a summariser, a citation generator covering APA, MLA and Chicago styles, a plagiarism checker and an AI detector. Chrome, Word and Google Docs extensions put it directly inside the apps people already write in.

Key facts: The paraphraser is the star: context-aware rewrites that improve flow and word choice, with a synonym slider for fine control. The summariser condenses articles into key points or bullet lists, and the citation generator removes the tedium of building a bibliography. Like all rewriting tools it needs a human proofread — output can shift tone or nuance, and its AI Humanizer should not be relied on to beat detection software.

Plans: Free costs $0 with paraphrases capped at 125 words, 2 modes (Standard and Fluency), a 1,200-word summariser and basic grammar checks — no plagiarism checker. Premium is $19.95/month, or $8.33/month billed annually ($99.95/year), with unlimited paraphrasing in all modes, a 6,000-word summariser, plagiarism checks and the full AI detector and Humanizer. Team plans start around $7.50/seat/month, and Premium carries a 3-day money-back window rather than a free trial.

Best for: students rephrasing quotes, bloggers refreshing old content and non-native writers polishing English. Use the free tier for occasional rewrites; if you rewrite daily or need plagiarism checks, Premium is one of the cheaper writing subscriptions available.
