QuillBot alternatives for people rewriting AI drafts at work

QuillBot is a paraphraser. That is a fine thing to be, and it is why students and researchers like it. But if you are sitting on an AI-written cold email, a LinkedIn post that reads like a press release, or a product page full of the same three sentence shapes, a paraphraser is not quite the tool you want. You want something that fixes tone and rhythm without changing what you meant.

This page lists six QuillBot alternatives plus QuillBot itself, with what each one costs, who it suits, and where it falls short. We make one of them (Plainspoke), so we have tried to be fair about where we are not the right pick. Prices were taken from vendor pages and third-party trackers in late summer 2026. Plans change, so confirm before you pay.

What to look for when you rewrite AI drafts for work

Paraphrasing swaps words. Rewriting a work draft means different things: cutting filler openers, breaking up even sentence lengths, removing claims you can't back up, and keeping your names, numbers and offer intact. When comparing tools, check three things:

  • Length limits per request. A 600-word cap is fine for an email and annoying for a case study.
  • Whether it is aimed at you or at a detector. Some tools are built mainly to get past AI detectors. That is a different goal from making a message read well to a person. (Detectors also flag plenty of human writing; see why AI detectors flag human writing.)
  • Billing. Several tools advertise a low monthly price that only applies if you pay for a year up front.

1. Plainspoke

Who it suits: People who write for work and send what they write: sales and recruiting emails, LinkedIn posts, resumes and cover letters, product descriptions. It checks AI-sounding patterns in professional copy and rewrites them. We have separate pages for cold email, LinkedIn, resumes and product descriptions.

Pricing: Current plans are on the pricing page. You can also sign up and try it on a real draft.

Weakness: It is not for schoolwork. If you need to paraphrase a source for an essay, QuillBot or Wordtune will serve you better, and we would rather say so. For a direct feature comparison, see Plainspoke vs QuillBot.

2. QuillBot

Who it suits: Anyone who paraphrases a lot and wants the lowest price. QuillBot's own pricing FAQ lists Premium at $8.33 a month billed annually ($99.95), $13.31 a month on a quarterly plan ($39.95 every three months) and $19.95 month to month. Reviewers report that Premium removes the paraphrasing word cap, adds nine modes, and bundles a summarizer, plagiarism checker, AI detector and humanizer.

Weakness: The free plan limits the paraphraser to 125 words per input, according to a pricing review, so you can't test it on a full email thread or page. Its modes (Formal, Academic, Creative and so on) are built around rewording rather than around the habits that make business writing read as machine-made. That is our judgment, not a QuillBot statement. Where QuillBot beats us: price, breadth of tools, and academic use.

3. Grammarly

Who it suits: People who want one editor for everything they type. Grammarly has a free plan, and trackers list Pro at $12 per member per month billed annually ($144 a year) or $30 on monthly billing. One review says the free plan includes 100 AI prompts a month and Pro includes 2,000, along with plagiarism and AI text detection and tone adjustments.

Weakness: The $12 figure is the annual rate, so you pay $144 at once, or $30 a month if you want flexibility. Grammarly is also a general editor. It will tidy grammar and tone, but it is not designed around removing the patterns that make a draft read as AI-written. See Plainspoke vs Grammarly.

4. Wordtune

Who it suits: Writers who work sentence by sentence and want several rewording options for an email they already half-wrote. The free plan gives 10 rewrites a day.

Pricing: Sources disagree here, so treat any number with care. Two trackers list Advanced at about $14 a month (30 rewrites a day) and Unlimited at about $20 a month, with annual billing cutting those to roughly $7 and $10. A third lists lower figures. Check wordtune.com before buying.

Weakness: Lower paid tiers cap daily rewrites, which matters if you process a lot of drafts. See Plainspoke vs Wordtune.

5. Undetectable AI

Who it suits: People who humanize large volumes of text and want a built-in detector check. A tracker reports $60 charged annually for 10,000 words a month, and monthly plans from $19 for 20,000 words. New accounts get 250 words of credit to test with.

Weakness: It is priced in words, and one review notes unused credits don't roll over. More important for work writing, the product is organized around passing detectors. That does not make a better email, and no humanizer is fully reliable against detectors anyway. See Plainspoke vs Undetectable AI.

6. WriteHuman

Who it suits: Short pieces where you want a few output variations to pick from. The free plan allows three requests a month of up to 250 words. Basic runs about $12 a month billed annually ($144 a year) for 80 requests of up to 600 words each; monthly billing costs more, with sources quoting $18 to $20.

Weakness: The 600-word limit on Basic means long pages must be split, and one reviewer warns that splitting can make tone uneven between sections. See Plainspoke vs WriteHuman.

7. ProWritingAid

Who it suits: Longer documents such as reports, whitepapers and case studies, where you want detailed style feedback more than automatic rewrites. One review checked against the vendor's pricing page lists Premium at $30 a month or $120 a year, Premium Pro at $36 a month or $144 a year, and a one-time lifetime license at $399. Premium includes over 20 writing reports.

Weakness: It is a critique tool. It points out problems in a draft rather than rewriting it into something you can send. It is the only option here with a lifetime license, which is a real advantage if you hate subscriptions.

Frequently asked questions

What is the best free alternative to QuillBot?

Grammarly, Wordtune and QuillBot all have free plans, but the limits differ. QuillBot's free paraphraser caps input at 125 words, Wordtune's free plan allows 10 rewrites a day, and Grammarly's free plan includes 100 AI prompts a month, according to pricing reviews. WriteHuman and Undetectable AI offer only small test allowances of about 250 words.

Is QuillBot good for rewriting AI-generated work emails?

It can reword them, and Premium is inexpensive at $8.33 a month on annual billing. Its modes are built around paraphrasing, though, so you may still have to fix tone and repeated sentence patterns by hand. A tool aimed at professional writing, such as Plainspoke, targets those problems directly.

Are AI humanizers the same as paraphrasers?

Not quite. A paraphraser rewords text. A humanizer tries to make AI-written text read as human, and many are tuned to pass AI detectors. For work writing, the better test is whether a real reader finds the message clear and specific.

Which QuillBot alternative is cheapest?

QuillBot itself is hard to beat at $8.33 a month on annual billing. Among the alternatives, ProWritingAid works out to $10 a month on annual billing, and Grammarly Pro is $12 a month annually. Undetectable AI lists $60 a year for 10,000 words a month. Monthly billing costs considerably more on almost every tool here.

Is Plainspoke meant for students?

No. Plainspoke is built for professional writing: cold email, LinkedIn, resumes, cover letters and product pages. It is not designed for schoolwork, and students looking for an essay paraphraser should look at QuillBot or Wordtune.
