QuillBot Review (2026) — 125-Word Free Paraphrasing Cap & Real Limits
Free TierParaphraserLearneo / Course Hero
QuillBot is widely recognized as the web's go-to AI paraphrasing and rewriting tool. Designed for students, researchers, and writers, it provides multi-mode sentence restructuring, vocabulary substitution, and grammar checking.
While QuillBot offers a genuinely useful free experience, its flagship Paraphraser tool enforces a strict 125-word cap per submission on the free plan, requiring users working on long essays or articles to break text into paragraph-sized chunks.
What you get for free on QuillBot
You can access QuillBot's basic features on the web without entering credit card details. The free tier includes:
- 125-word Paraphrasing Cap: Free users can rewrite up to 125 words per prompt across two modes: Standard (balances text rewording with original meaning) and Fluency (ensures grammatical correctness).
- Uncapped Grammar Checker: Full access to QuillBot's grammar, spellchecker, and punctuation tool without word count restrictions.
- Summarizer (up to 2,500 words): Free users can condense documents or articles up to 2,500 words into key bullet points or paragraph summaries.
- Free Citation Generator: Create APA, MLA, and Chicago style citations for books, web pages, and academic journals at no cost.
- Synonym Slider (Limited): Adjust how many words are replaced with synonyms, though the free slider is restricted to lower frequency changes.
