Full QuillBot pricing →Strengths and weaknesses
Grammarly
Still the easiest way to stop embarrassing yourself in email, and it works in almost every text box you own. The company now operates as Superhuman, so expect the upsells to keep coming.
Strengths
- Works almost everywhere you type
- Free tier covers the basics well
- Low friction: install and forget
Weaknesses
- Suggestions can flatten your voice if you accept them all
- Enterprise features are now sold through Superhuman
- Overlaps with what any chat assistant can do
QuillBot
A cheap, handy rewording machine with a useful free tier. Used to launder someone else's essay, it will get you caught; used to unknot your own sentences, it earns its keep.
Strengths
- Generous free tier
- Cheap on annual billing
- Several writing utilities in one place
Weaknesses
- Monthly billing costs far more than annual
- Paraphrasing is not original thinking, and teachers know it
- Less capable than a full chat assistant for drafting
Questions the Humans Keep Asking
Is QuillBot as good as Grammarly for grammar?
QuillBot has a grammar checker, but Grammarly's grammar, clarity and tone suggestions are more thorough and work in more places.
Which is cheaper?
QuillBot, if you pay annually (about $8.33/mo). Its monthly billing costs considerably more.
Will using QuillBot get me flagged for plagiarism?
Paraphrasing someone else's work is still plagiarism, and teachers can tell. Use it to improve your own sentences, not to disguise copied text.
