Key Features: What Makes QuillBot Tick?
QuillBot AI is built around a suite of interconnected tools powered by advanced language models, drawing from vast datasets to assist with everything from rephrasing sentences to ensuring ethical writing practices. It processes user input in real-time, offering suggestions that enhance fluency, tone, and originality without fully automating the process—putting the emphasis on collaboration between human and AI. Trusted by over 35 million users worldwide, including students at 140+ institutions, QuillBot shines in academic and content-heavy environments. Here are some standout capabilities:
- Paraphraser: Rewrites text in multiple modes (e.g., Standard, Fluency, Formal, Creative, Simple, Expand, Shorten) with a synonym slider for customization, helping avoid plagiarism while preserving meaning.
- Grammar Checker: Scans for spelling, punctuation, and grammar errors, providing quick fixes and fluency improvements.
- Plagiarism Checker: Compares text against billions of web pages, highlighting matches with sources and percentages for thorough originality checks.
- AI Detector and Humanizer: Identifies AI-generated content and offers ways to “humanize” it, making it undetectable while maintaining quality.

Pricing: Transparent Tiers for Pros
QuillBot keeps things straightforward with its pricing, offering a robust free tier for casual users and premium options for those needing unlimited access. You can pay in USD via credit card or PayPal, with annual billing providing the best value—often around 50% off compared to monthly. Compared to competitors like Grammarly (which starts at $12/month annually), QuillBot is more budget-friendly, especially for students, but note the plagiarism checker’s monthly page limits even in premium. If you’re testing the waters, the free plan lets you dip in without commitment, and premium comes with a 3-day money-back guarantee. For teams, reaching out via their site could unlock customized demos or discounts.

| Premium | $8.33/month (billed annually) | Unlimited paraphrasing, all modes, advanced grammar, unlimited AI detection, plagiarism checks (up to 20 pages/month) | Students, writers, and professionals needing full features |
| Team | Contact for quote (starts around $179.90/year for small teams) | All premium features plus user management, centralized billing, and dedicated support | Organizations or educational institutions with multiple users |
