Claude gives the most natural, meaning-faithful rewrites of long passages if you tell it the audience and tone. ChatGPT is almost as good and has a cheaper $8 Go plan. Wordtune is the best cheap tool for quick sentence alternatives in your browser, and Grammarly suits people who want rewrites and grammar checks inside every app. For free options, LanguageTool and Hemingway Editor both have useful free paraphrasers. QuillBot itself still ranks #1 in our best AI paraphrasing tools for its modes and value.
Why people look for QuillBot alternatives
Paraphrases that sound mechanical
Reviewers often say QuillBot's output reads slightly robotic, especially at high synonym settings, and can drift from the original meaning. Chatbots such as Claude rewrite whole passages more naturally when you describe the reader.
Tight free limits
The free paraphraser stops at 125 words and two modes, and the humanizer is capped too. Some rivals give more free rewrites a day, or unlimited use with a general chatbot's free plan.
Weak grammar teaching
QuillBot's grammar checker fixes errors quickly but explains little. Writers who want to learn why something is wrong, or want help in every app, often move to Grammarly or LanguageTool.
Billing and refunds
Refunds are issued only where the law requires, and many negative reviews mention renewals people forgot. Users who only need help a few times a year may prefer free tools.
It is not a drafting tool
QuillBot rewrites text you already have. Its AI chat is far behind Claude or ChatGPT at writing a first draft from notes.
by Anthropic · from Free; Pro $17/month billed yearly or $20 monthly · free plan
8.6/10
Claude ties with QuillBot at the top of our paraphrasing ranking because it rewrites for meaning rather than swapping words. Tell it who the reader is and what tone you want, and it will restructure a whole page so it reads naturally, keep technical terms intact and explain what it changed if you ask. The free plan is fine for occasional use; Pro costs $20 a month or $17 a month billed yearly. What you lose is QuillBot's quick modes, the synonym slider and word-by-word highlighting, so small sentence tweaks take a little longer.
Versus QuillBot:More natural and faithful on long text; no one-click modes or highlighted changes.
by OpenAI · from Free; Go $8/month; Plus $20/month · free plan
8.5/10
ChatGPT rewrites text in any style you describe, from simpler English to a formal report, and can draft new text from your notes, which QuillBot cannot do well. The free plan offers unlimited text chats, Go costs $8 a month for more uploads and tools, and Plus at $20 adds stronger reasoning models. It ranks just behind Claude and QuillBot in our paraphrasing ranking. The downside is control: it may change more than you asked, so tell it to keep the meaning and list every change.
Versus QuillBot:Far better at drafting and big rewrites; less predictable than QuillBot's modes for small edits.
#3 · Best for quick sentence alternatives in the browser
Wordtune
by AI21 Labs · from $4.89/month billed yearly (Advanced) · free plan
8.3/10
Wordtune is the closest like-for-like rival for short edits. Highlight a sentence and it offers several alternative versions, plus options to make it shorter, longer, more casual or more formal. The free plan gives 10 rewrites and AI suggestions a day, 3 summaries a month and unlimited spelling and grammar checks. Advanced costs $4.89 a month billed yearly for 30 rewrites a day, and Unlimited costs $6.99 a month yearly or $9.99 monthly, with a 3-day trial. It lacks QuillBot's citation generator, plagiarism checker and AI detector.
Versus QuillBot:Cheaper and quicker for single sentences; far fewer extra student tools.
by Superhuman Platform Inc. · from Free; Pro $12/month billed yearly ($144/year) · free plan
8.2/10
Grammarly's AI rewrites work in almost any text box: highlight a sentence in Gmail, Google Docs or Word and ask it to shorten, simplify or change the tone. It is also the stronger grammar checker, with clear explanations, and it ranks #1 in our grammar checker ranking. The free plan includes unlimited basic checks and 100 AI prompts a month; Pro costs $144 a year or $30 month-to-month. Its paraphrasing controls are simpler than QuillBot's, with no modes or synonym slider.
Versus QuillBot:Better grammar help and works where you type; costs more and has fewer paraphrase controls.
#5 · Best for free multilingual checking with light paraphrasing
LanguageTool
by LanguageTooler GmbH · from Free; Premium priced by region · free plan
7.9/10
LanguageTool checks grammar and style in more than 25 languages and includes an AI paraphraser. The free plan allows 3 sentence rephrases a day and checks up to 2,000 characters per text field; Premium adds unlimited paraphrasing and checks up to 150,000 characters. Its core engine is open source, so organisations can run their own server. It is a sister company of QuillBot, as both belong to Learneo, so it is a different product rather than a fully independent rival. Choose it if you write in several languages.
Versus QuillBot:Better multilingual grammar checking and an open-source core; much weaker as a dedicated paraphraser.
#6 · Best for fiction writers and long manuscripts
ProWritingAid Rephrase
by Orpheus Technology · from Free; Premium priced by region, yearly or lifetime · free plan
7.7/10
ProWritingAid is an editing suite for long writing, and its Rephrase feature suggests alternative versions of a sentence inside that editor. The free plan gives 10 rephrases a day plus small line-editing reports; Premium makes rephrasing unlimited and adds detailed reports on style, repetition and readability across whole chapters. It also sells a one-off lifetime licence, with a 3-day money-back guarantee on annual and lifetime plans. It suits novelists and report writers more than students who need quick paraphrases and citations.
Versus QuillBot:Deeper editing reports for long work; fewer paraphrase modes and no citation tools.
by Boondoggle Studio · from Free web editor; Hemingway Editor Plus paid · free plan
7.2/10
Hemingway Editor helps you make writing clearer rather than just different. It highlights long sentences, passive voice, adverbs and complex words, and gives a reading-grade score, so you learn to simplify on your own. The site also offers a free online paraphrasing tool and AI proofreader. Hemingway Editor Plus adds AI fixes for the highlighted problems, grammar checks and tone changes, with a 2-week trial and no card needed. It is a good free companion for students who overuse a paraphraser to sound more formal.
Versus QuillBot:Teaches clear writing for free; far fewer rewrite modes and no student research tools.
Rewriting whole passages for a new reader:Claude or ChatGPT. Describe the audience and ask it to keep the meaning.
Quick one-sentence alternatives: Wordtune.
Grammar help and rewrites inside Gmail, Docs and Word:Grammarly.
Several languages: LanguageTool.
Novels or long reports: ProWritingAid.
Learning to write more plainly, for free: Hemingway Editor.
If you use QuillBot's citation generator, summarizer and AI detector as much as the paraphraser, it may still be the best value at $99.95 a year. Our best AI paraphrasing tools and best AI summarizer rankings compare the options in detail.
Switching tips from our editors
Turn off auto-renewal before your renewal date. QuillBot only refunds where the law requires, so a missed date usually means another paid period.
Export your saved citation lists to Word before you leave; the citation generator can export whole lists.
Copy anything you need from your paraphraser and humanizer history, and download documents stored in QuillBot Flow.
If you only need a break, pause Premium for 30 to 90 days instead of cancelling.
When moving to a chatbot, save a reusable instruction such as "Rewrite for [audience], keep all technical terms and numbers, and list every change" to get QuillBot-like control.
Rewriting a sentence or passage in different words while keeping its meaning. Other people's ideas still need a citation after you paraphrase them.
Synonym slider
A QuillBot control that sets how many words get swapped for synonyms. Higher settings change more words and risk changing the meaning.
Freeze Words
A QuillBot setting that locks chosen words or phrases so the paraphraser never changes them.
AI humanizer
A tool that rewrites AI-generated text so it sounds more natural. It does not reliably stop AI detectors from flagging the text.
False positive
When an AI detector wrongly labels human writing as AI-generated.
