QuillBot Premium bundles paraphrasing in 9 modes with a plagiarism checker, AI detector, humanizer and summarizer for $8.33/month billed annually. Wordtune does one job — offering polished rewrite options right where you type — and its Unlimited plan removes every cap for $6.99/month billed annually. Students and anyone who must check originality should pick QuillBot; professionals who live in email and docs should pick Wordtune.

What the pricing pages don’t make obvious
Wordtune’s terms are blunt in a way its marketing is not: its plans page states that Wordtune does not offer refunds — you can cancel before the next billing cycle, but there are no refunds or credits for partial periods. That makes the 3-day free trial on paid plans the only real safety net, so set a reminder before it converts. There is also a channel trap: the iOS app has historically sold its premium subscription at a much higher price than the web plans page, so subscribe on the web, not in the app, and check which price you are actually being shown.
On the QuillBot side, the detail most coverage skips is that Premium’s plagiarism allowance is capped at 25,000 words a month — generous for essays, but a real ceiling for editors checking long manuscripts — while the free plan’s 125-word paraphrasing cap is per run, in only 2 of the 9 modes.
Where QuillBot wins: a student’s and editor’s toolkit
QuillBot is the broader buy. One Premium subscription covers paraphrasing, grammar checking, summarizing up to 6,000 words, citation generation, an AI detector, a humanizer, and the plagiarism checker. For academic writing — where Academic mode and an originality check are not optional extras — nothing in Wordtune answers it. We put that toolkit in context in our QuillBot vs Grammarly comparison and in the free-tier breakdown in our QuillBot review.
Where Wordtune wins: rewrites without leaving the page
Wordtune, from AI21 Labs, is narrower and smoother: highlight a sentence in Gmail, Docs or the web app and get a set of clearer, shorter, more formal or more casual alternatives, plus summaries of long documents. There is no separate dashboard to learn and no mode menu to manage. Its free tier is also more usable day to day — 10 full rewrites a day, every day, against QuillBot’s 125-word snippets. That focus is exactly what we weighed in our Grammarly vs Wordtune comparison: Wordtune wins when the sentence, not the document, is the unit of work.
Which should you pick?
- Pick QuillBot Premium if you are a student, researcher or editor who needs paraphrasing modes, summaries and a plagiarism check in one $8.33/month (annual) subscription.
- Pick Wordtune Unlimited if you write professional English all day — especially as a second language — and want unlimited rewrites inside the apps you already use, for $6.99/month billed annually.
- Stay free if your use is occasional: Wordtune’s 10 rewrites a day covers light email polish, and QuillBot’s free tier covers short paraphrases. Pay only when a cap interrupts real work.
