The best QuillBot alternative depends on what you used QuillBot for. If you mainly paraphrased, look at dedicated rewriting tools or a general AI assistant you can prompt carefully. If you mainly fixed grammar, a grammar checker with explanations will serve you better. If you wanted everything in one place (paraphrasing, grammar, summaries, citations and checks), look for an all-in-one writing suite.
A quick disclosure before the list: ZeroTell publishes this blog and makes a paraphraser, grammar checker, plagiarism checker and other writing tools, so we compete with several products below. We've stuck to publicly documented features, avoided prices and limits that change often, and tried to say what each tool does well.
What QuillBot offers, for context
QuillBot is best known for its paraphraser, which offers several rewriting modes and a synonym slider. Over time it has added a grammar checker, summarizer, citation generator, plagiarism checker, AI detector, translator and browser and word-processor integrations. It has a free tier with limits and a paid plan.
People usually look for an alternative for one of these reasons:
- The free tier's limits don't fit how much they write.
- They want stronger grammar explanations or tone feedback.
- They found the paraphrases too close to the original or too generic.
- They want a tool that fits a different workflow, such as working inside a specific editor.
- Their school prefers a particular tool or discourages paraphrasers.

The alternatives in more detail
1. ZeroTell
ZeroTell is our product, so read this section with that in mind. It brings a paraphrasing tool, paragraph and sentence rewriters, a grammar checker, a summarizer, a citation generator, a plagiarism checker and an AI detector into one workspace. The idea is that a student can rewrite a sentence, check the paragraph against sources and fix citations without switching sites.
Good for: students who want writing help and self-checks together. Keep in mind: like any rewriting tool, output needs your review for accuracy and voice.
AI ParaphraserReword text in several modes2. Grammarly
Grammarly is widely used for grammar, spelling, clarity and tone suggestions across browsers, desktop apps and many websites. It has added generative AI features for rewriting and drafting. Its strength is catching errors and explaining them as you type.
Good for: emails, everyday documents and learners who want explanations. Keep in mind: paraphrasing is not its core focus, and feature availability varies by plan.
3. Wordtune
Wordtune focuses on offering several rewrites of a sentence you've highlighted, with options to make it shorter, longer, more formal or more casual. It suits writers who want to choose between alternatives rather than accept one rewrite.
Good for: polishing individual sentences. Keep in mind: it's a rewriting tool, not a checker for plagiarism or citations.
4. LanguageTool
LanguageTool checks grammar and style in many languages, with an open-source core and browser and office add-ons. It's a strong choice if you write in more than one language or want a tool that respects regional spelling.
Good for: multilingual writers and people who prefer open-source software. Keep in mind: it's primarily a checker, so heavy rewriting isn't its job.
5. Hemingway Editor
Hemingway highlights long sentences, passive voice, adverbs and complex words so you can simplify text yourself. It doesn't paraphrase for you, which some writers see as a feature: you learn to fix the patterns.
Good for: making dense writing readable. Keep in mind: no paraphrasing or source checking.
6. Microsoft Editor and Copilot in Word
If you already write in Microsoft Word, its built-in editor offers spelling, grammar and refinement suggestions, and Copilot can rewrite selected text where your subscription includes it.
Good for: people who don't want another tool. Keep in mind: what you get depends on your license and organization settings.
7. Scribbr
Scribbr is aimed at students, with guides and tools for citations, paraphrasing, grammar and proofreading. It offers a plagiarism checker that Scribbr says uses Turnitin's technology, generally as a paid, per-document service.
Good for: students who want academic-focused tools and guides. Keep in mind: check which features are free and which are paid.
8. General AI chatbots
Chatbots can rephrase text in any style you describe, explain why a sentence is unclear and suggest structure changes. They're flexible, but quality depends on your prompts and they can change meaning or invent details. Our list of prompts for editing AI-assisted text shows how to keep them focused.
Good for: writers who want explanations and flexible edits. Keep in mind: always verify facts and check that the meaning hasn't shifted.
How to choose
Ask yourself four questions:
- What do I actually need? Rewriting, grammar correction, readability, checks, or all of these?
- Where do I write? Pick a tool that works inside your usual editor or browser.
- Do I want suggestions or rewrites? Suggestions teach you; rewrites save time but need more review.
- What does my school or employer allow? Some courses restrict paraphrasing tools or AI assistance. Check before you rely on one.
Matching a tool to your situation
You're a student writing research papers. Prioritize tools that combine paraphrasing help with citation formatting and a way to self-check for missing quotes. An all-in-one suite or an academic-focused tool fits best.
You're writing in a second language. Choose a tool that explains why it suggests a change. Grammar checkers with explanations, or a chatbot you can ask "why is this sentence unclear?", teach you patterns you'll reuse.
You write lots of emails and documents at work. A grammar and tone tool that works inside your email client and browser will save more time than a standalone paraphraser.
You want to become a stronger writer. Readability tools like Hemingway, which highlight problems without fixing them, push you to make the changes yourself.
Using any paraphraser responsibly
Whichever tool you choose, the same rules apply.
- Paraphrasing a source still needs a citation. Rewording someone's idea doesn't make it yours. See our guide to mosaic plagiarism for how swapped-word rewrites go wrong.
- Check the meaning. Automated rewrites can flip a qualification or drop a key detail.
- Keep your voice. If every sentence goes through a rewriter, your paper can end up sounding generic.
- Follow your policy and disclose when required.
Key takeaways
- Pick an alternative based on what you used QuillBot for: rewriting, grammar, readability or all-in-one checking.
- Grammar-focused tools explain errors; rewrite-focused tools offer alternatives; chatbots are flexible but need careful review.
- ZeroTell is our own all-in-one option. Compare it fairly against the others.
- No tool removes the need to cite sources and follow your school's or employer's rules.
