A paraphraser rewrites what you already have, clearer, shorter or in another tone, without changing the meaning. Free limits are where these tools differ most.
QuillBot is the dedicated paraphraser: Premium ($19.95/mo) unlocks unlimited paraphrasing in 9+ modes. Wordtune is the cheapest upgrade for sentence-by-sentence rewrites. To reword longer passages for free, paste them into ChatGPT.

Monthly prices in US dollars before tax, from each vendor's official pricing (US list price; weekly-billed plans converted to a monthly figure). Updated November 2, 2026
Started as a paraphraser and still leads with it: Premium unlocks unlimited paraphrasing in 9+ modes, an unlimited AI humanizer and a 25,000-word monthly plagiarism checker. Team ($7.50/mo) is per seat, billed annually.
Pick it if: you're a student or ESL writer reworking existing text.
Where it falls short: Free stops at 125 words, and humanized output can still trip AI detectors.
Full QuillBot pricing →Sentence-level rewrites and tone shifts on text you've already drafted. Free gives 10 rewrites a day; Advanced ($6.99/mo) raises that to 30, and Unlimited ($9.99/mo) removes the cap.
Pick it if: you polish sentences one at a time and want it cheap.
Where it falls short: It only rewrites and won't draft new long-form text; Free and Advanced caps are tight.
Full Wordtune pricing →Pro ($30/mo) adds full-sentence AI rewrites and tone adjustment on top of the free real-time grammar, spelling and tone checks that work everywhere you type.
Pick it if: you want rewrites suggested inside the apps where you write.
Where it falls short: Rewrites are generic and rule-bound next to a real LLM, and Pro's monthly list price is steep.
Full Grammarly pricing →Free includes unlimited text chats, so you can paste whole paragraphs and ask for a simpler, more formal or shorter version as often as you like.
Pick it if: you paraphrase occasionally and don't want another subscription.
Where it falls short: It's a general assistant: you paste text in and copy results back by hand.
Full ChatGPT pricing →Paraphrasing changes the words, not the origin of the idea. QuillBot Premium's plagiarism checker (25,000 words a month) and Grammarly Pro's plagiarism detection help you check overlap before you submit, but neither replaces citing the source.
Yes, with limits: Free paraphrases up to 125 words and allows the humanizer 6 times a day. Premium removes both limits and adds the plagiarism checker.
QuillBot for paraphrasing whole passages in different modes and for plagiarism checks. Wordtune for cheap sentence-level rewrites and tone shifts.
