QuillBot is the default recommendation for a reason, it's fast, versatile, and works everywhere. If you only try one paraphrasing tool, make it this one.
What holds up
Multiple paraphrasing modes: Standard, Fluency, Formal, and more
Free tier includes paraphrasing, grammar check, AI detection, and translation
Browser and desktop extensions for use anywhere you write
Premium plan ($8.33/month) is cheaper than Grammarly
What to know
Can sound slightly mechanical on longer texts
Full document runs can mess up sentence structure
Free version limits paraphrasing length
Expert verdict
QuillBot is the closest competitor to Grammarly. It has apps and extensions you can install on your desktop, mobile device, or web browser, so you can get grammar and spelling help wherever you go.
For free, you can use it to detect AI-generated text, paraphrase, translate, and more. If you choose to sign up for QuillBot's premium plan ($8.33 per month, billed annually), you get access to advanced writing suggestions, tone insights, unlimited paraphrasing, and more.
For academic style, I actually still use QuillBot but only in small chunks, then tweak the sentence flow myself. Full doc runs through QuillBot tend to mess up structure too much imo.
If passing AI detectors is your primary goal, WalterWrites AI is the community's top pick, multiple Reddit users independently called it 'scary good' and 'the smoothest' for keeping output human-sounding.

walterwrites.ai: was by far the most natural and best at bypassing AI detectors. it's scary good for anyone who needs plagiarism-free, human-like content.
Wordtune isn't the tool for full-document rewrites, but for polishing a paragraph or adjusting tone on the fly, it's genuinely useful, especially when chained with a heavier paraphraser like QuillBot.
What holds up
Intuitive interface with multiple tone suggestions per sentence
Good for adjusting tone: casual, formal, concise, or expanded
Free version available with basic limits
Recently launched dedicated paraphrasing tool
What to know
Free version is very limited, premium required for full use
Not designed for full-document paraphrasing
Less effective on longer texts compared to QuillBot
From the community
More of a writing enhancer, but can be used to paraphrase short passages. It's intuitive and gives different tone suggestions. However, it's limited unless you're on the premium plan.
Wordtune just launched their own paraphrasing tool, I have been using them for quite some time to help me with my online MBA abroad since I'm not a native speaker, they have paid options, but the free one is just enough for what I need.
Paraphraser.io is the tool you reach for when you need something fast and free with no strings attached. Don't expect magic, but for a quick draft or light rewording, it gets the job done.
What holds up
Free to use with no account required
Decent word count limits for a free tool
Fast results for quick rewording tasks
Useful for light paraphrasing of short content
What to know
Output can feel choppy or inconsistent
Not great at maintaining natural tone on longer texts
Still requires manual editing for polished results
From the community
Free to use with basic features, decent for quick rewording but not always great at keeping a natural tone. Sometimes the sentences feel choppy or inconsistent. Still useful for light paraphrasing.
Grammarly Rewrite won't do a full document overhaul, but if your goal is polished, clear writing rather than AI bypass, it's the most reliable finishing tool in the stack, and the free tier is genuinely useful.
What holds up
Excellent for improving clarity, tone, and sentence structure
Works as a browser extension across virtually every writing platform
Free version covers grammar and spelling without aggressive upselling
Trusted by millions with a long track record of accuracy
What to know
Not a full paraphraser, limited to sentence-level rewrites
Premium plan required for full rewrite and tone features
Free version frequently prompts upgrades to premium
Expert verdict
QuillBot is far less intrusive than Grammarly, avoiding copious underlining that pushes premium suggestions.
Not a full paraphraser, but it offers alternative sentence structures. It's better for improving clarity and correctness rather than full rewrites, but still useful in combination with other tools.
