Wordtune is cheap, with Advanced at $6.99/mo and Unlimited at $9.99/mo, but it only rewrites text you've already written and won't draft new long-form content. Free and Advanced also cap rewrites at 10 and 30 a day.
QuillBot Premium adds unlimited paraphrasing in 9+ modes plus a plagiarism checker. Claude and ChatGPT draft from scratch as well as rewrite, on free plans. Grammarly is the pick for real-time checks with tone detection.

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
QuillBot Premium ($19.95/mo) includes unlimited paraphrasing in 9+ modes, an unlimited AI humanizer and AI chat, and a plagiarism checker (25,000 words a month).
Pick it if: you want more rewrite modes and a plagiarism check in one tab.
Where it falls short: The free tier paraphrases only 125 words at a time, and humanized output can still trip AI detectors.
Full QuillBot pricing →Claude is built for nuanced writing and document analysis; the free plan handles drafting and editing, and Pro ($20/mo) adds unlimited projects for keeping drafts and notes together.
Pick it if: you need first drafts of articles or reports, not just better sentences.
Where it falls short: Usage caps are smaller than ChatGPT's.
Full Claude pricing →ChatGPT Free has unlimited text chats, so there's no daily rewrite counter; Go ($8/mo) adds memory and projects.
Pick it if: you rewrite and draft a lot and Wordtune's daily caps get in the way.
Where it falls short: Output quality varies between model tiers.
Full ChatGPT pricing →Grammarly Free checks grammar and spelling as you type with a tone detector and 100 AI prompts a month; Pro ($30/mo) adds full-sentence rewrites and tone adjustment.
Pick it if: you want corrections everywhere you type, not on demand.
Where it falls short: Pro costs far more than Wordtune Unlimited, and its rewrites are rule-bound next to a chatbot.
Full Grammarly pricing →Wordtune and QuillBot work on sentences you've already drafted; Claude and ChatGPT will write the first draft too. If your problem is a blank page, a sentence rewriter won't help however many rewrites the plan allows. If your problem is clunky phrasing in a finished draft, Wordtune Unlimited is already one of the cheapest fixes.
Yes. Wordtune Free includes 10 rewrites and AI suggestions a day, 3 AI summarizations a month and unlimited grammar and spelling checks.
QuillBot covers more jobs: unlimited paraphrasing in 9+ modes, an AI humanizer and a plagiarism checker on Premium. Wordtune is cheaper and focused on contextual sentence rewrites and tone shifts.
