Is QuillBot free?
Yes — there is a free plan you can use without paying.
Free plan includes paraphrasing (up to 125 words at a time), basic grammar fixes, limited AI detection, and basic summaries. The paid Premium plan removes the word limit and unlocks full humanization, plagiarism checking, and advanced grammar suggestions.
How to use it well
Use it only to reword ideas and sentences you already drafted yourself, not someone else's source text
Compare every AI-suggested rewrite against your original sentence-by-sentence, since paraphrasers can quietly change meaning
Check your course's AI-tool policy before using it on graded work
Limitations to know about
Cannot generate original content or ideas from scratch, only reworks text you provide
Free plan restricts both word count (125 words per rephrase) and mode selection
Its plagiarism/AI-detection tools are not as authoritative as dedicated services like Turnitin
No teacher or editorial oversight is built in, so altered meanings can go unnoticed
Alternatives to QuillBot
A writing assistant that checks grammar, clarity and tone as you type.
Frequently asked questions
Is using QuillBot to paraphrase considered cheating or plagiarism?
Using QuillBot to reword your own already-drafted sentences for clarity is generally seen as legitimate self-editing. However, using it to reword someone else's source material closely enough to avoid a plagiarism-detector match while skipping citation is still academic dishonesty, since the underlying ideas remain someone else's.
Does QuillBot have a free plan, and what's included?
Yes — the free plan allows unlimited daily paraphrases of up to 125 words at a time, using the Standard and Fluency modes, plus basic grammar checking. Premium removes the word cap and unlocks 10+ additional paraphrasing modes along with fuller plagiarism-checking and citation features.
