Tool profile
QuillBot
QuillBot is an AI-powered writing tool that paraphrases, summarizes, checks grammar, and assists with citation and translation. It rewrites text in multiple modes to change tone, style, or complexity while preserving the original meaning. It also includes a full-document grammar checker, a plagiarism detector, and an AI text summarizer.
Models and pricing
Casual or occasional paraphrasing of short texts
Limits you to paraphrasing 125 words at a time, gives access to only 2 of 8 paraphrasing modes (Standard and Fluency), and summarizes up to 1,200 words. No plagiarism checker. Good enough for light, infrequent use but quickly hits walls for serious work.
Users who want to try Premium before committing long-term
Unlocks all 8 paraphrasing modes (including Formal, Academic, Creative, and more), unlimited paraphrasing length, faster processing, advanced grammar suggestions, plagiarism checker (up to 20 checks/month), and summarization up to 6,000 words. Most expensive per-month option but no long-term commitment.
Regular users who want a middle-ground commitment
Identical features to monthly Premium at a meaningfully lower per-month cost. A reasonable choice if you use QuillBot consistently for a school semester or a defined project period.
Heavy users such as graduate students, frequent writers, or content professionals
Same full feature set as other Premium tiers at the lowest available cost. Best value if QuillBot is a regular part of your workflow. At roughly $50/year, it is cheaper than most competing writing tools with comparable paraphrasing capability.
Which model should you use?
Start with the Free plan to see if QuillBot fits your workflow; if you find yourself hitting the word limit or wanting modes like Academic or Formal regularly, the Annual Premium plan at $4.17/month is the obvious choice for anyone who will use it more than a few times a week.
