What is QuillBot?
QuillBot is an AI writing suite best known for its paraphraser, which rewrites sentences and paragraphs in different styles. It also includes a grammar checker, summarizer, translator, citation generator, AI detector and humanizer.
The free plan covers the basics with limits, such as paraphrasing up to 125 words at a time in two modes. Premium removes the paraphrasing limits and unlocks all modes plus a plagiarism checker.
It’s especially popular with students and researchers who need to rephrase and summarize a lot of text.
Key features
- Paraphraser: rewrite text in 9 built-in modes, plus custom modes on Premium.
- Grammar checker: fix spelling, grammar and punctuation.
- Summarizer: condense long text into key points or paragraphs.
- AI detector and humanizer: check for AI-generated text and make writing sound more natural.
- Plagiarism checker: scan up to 25,000 words a month (Premium).
- Translator and citations: translate text and generate citations.
Pricing plans
| Plan | Price | Good for |
|---|---|---|
| Free | $0 | Light paraphrasing and grammar fixes |
| Premium | $8.33/month billed annually ($99.95/year), or $19.95 billed monthly | Regular writers who need full paraphrasing and plagiarism checks |
| Team | Custom | Schools and organizations buying several seats |
Which plan should you pick? Start on Free. If you paraphrase longer passages often, Premium on annual billing is the best value, at well under half the monthly price.
QuillBot free plan: what you get
| Feature | Details |
|---|---|
| Paraphraser | Up to 125 words at a time |
| Paraphrasing modes | 2 (Standard and Fluency) |
| Summarizer | Up to 1,200 words |
| Grammar checker | Basic fixes |
| Plagiarism checker | Premium only |
The catch: The 125-word paraphrasing limit means you can only rewrite a short paragraph at a time, which gets tedious for longer documents.
Who is QuillBot for?
- Students: rephrase and summarize research.
- Researchers: condense long papers into key points.
- Content writers: refresh and reword existing text.
- Non-native English writers: find clearer ways to say things.
Consider something else if you need long-form content written from scratch, or work mainly in tools QuillBot doesn’t support.
