QuillBot FAQ
What does the QuillBot free tier actually include?
Free tier covers up to 125 words per paraphrase, three paraphrasing modes (Standard, Fluency, Creative), grammar checker, and the summariser at 1,200 word limit. Premium ($9.95/mo on the annual deal above) unlocks unlimited word count, all seven modes, plagiarism checker, and the tone detector.
Will QuillBot's paraphraser get my essay flagged for AI use by Turnitin?
QuillBot output can still be detected as AI-assisted by Turnitin's AI-writing detector and similar tools. Universities increasingly treat unattributed AI use as a policy violation regardless of detection — cite QuillBot's involvement in your methodology rather than relying on it to bypass detection.
How does the QuillBot Chrome extension compare to Grammarly?
Grammarly wins on real-time grammar correction across the entire web. QuillBot wins on paraphrasing and tone-shifting within selected text. Many users keep both installed and use QuillBot when they need to actively reword, Grammarly when they need a passive proofreader.
How often are QuillBot codes updated?
Our editors verify every QuillBot code at least once a week. Codes that stop working are marked as expired within 48 hours. The "Verified" badge means a human tested it in the last 7 days.
What if a QuillBot code doesn't work?
Try the next code in our list — codes are sorted by recency. If none work, the merchant may have ended the promotion. You can also report it from the deal page; we'll re-verify and update within 24 hours.
