Our verdict
Grammarly is the better choice for businesses: it improves writing everywhere and adds team style controls. QuillBot is the better value for individuals who frequently paraphrase or summarise.
Grammarly and QuillBot are both AI writing helpers, but they started with different jobs. Grammarly checks grammar, clarity and tone wherever you type and has grown into a business writing assistant with style guides and brand tones. QuillBot is best known for its paraphraser — rewriting sentences in different styles — plus a grammar checker, summariser and citation tools, at a very low price.
Choose Grammarly if…
- You want real-time checking in email, docs and browser apps

Choose QuillBot if…

- You want the lowest-cost premium plan
