Do NOT buy the paid version
Do NOT get Grammarly premium. It is a total scam. The software does not perform as you would expect. I paid for the Premium version and it writes like horrible AI. When I tried to cancel it, there is no customer service, no one to contact. I opened a ticket and waited for a response. Three weeks went by when I got an email saying they “are still reviewing the ticket”. I contacted my credit card company and they reached out to Grammarly and Grammarly said that there is no record of me trying to cancel the subscription. It is a scam.
