QuillBot is a aI paraphrasing tool with grammar checker, summarizer, and citation generator. It handles paraphrasing, grammar, summarizer, and citations, and it's best suited for students and writers wanting paraphrasing and grammar tools. It has been around since 2017, giving it a 9-year head start in building out integrations and refining the product.

The free plan is free with 125-word limit — enough for most people to evaluate whether it fits. It's aimed at individual users, so it's fast to set up but may lack team-management features if you scale.

pros

Includes Paraphrasing as a core feature, purpose-built for ai writing workflows
Includes Grammar as a core feature, purpose-built for ai writing workflows
Free with 125-word limit — generous enough for most small teams to get real work done
Includes summarizer alongside the core feature set — fewer separate tools needed

cons

Free plan has meaningful restrictions: free with 125-word limit
Fewer built-in features means you may need additional tools to cover gaps
Ecosystem of third-party integrations is smaller than the market leaders in ai writing
Limited team/admin features if your organization eventually scales up
