The short answer
Choose Grammarly if…
Our pick for most people
- you want a free tier that covers grammar and spelling
- you mainly need grammar and spelling checks on your own writing as an individual
- you want per-seat pricing if you upgrade to a paid plan
Choose Copy.ai if…
- you run a team that needs workflow automation at scale
- you need 75 or more seats with monthly workflow credits
- you want a flat team price with seats included
Bottom line: Grammarly is the better pick — its free plan handles basic grammar and Pro costs $30/month per user for heavier AI use.

Grammarly!! Are you listening to your users?? This new AI update is so incredibly disappointing, and I can see that many people agree. It feels like the writing suggestions are worse, and all this AI slop is discouraging me from using Grammarly. PLEASE revert back to the old format!! …
Canclled my Grammarly subscription after 5 years I use to love Grammarly before it changed. I could just copy and paste an email or what ever I had written and it would automatically suggest changes to spelling and grammar,it was so simple. …
Why has Grammarly gotten so bad? I use IOS to write, and have been using Grammarly to check my grammar (you know, like how it’s supposed to?) for years, but recently, especially since its introduction of AI, the quality has decreased exponentially. …
Why is grammarly premium adding commas in the middle of words like thi,s and tha,t. The app is now useless. I have tried everything on my m5. Uninstalled installed. Updated my word, grammarly. Cleared cache. All the solutions on the internet does not seem to work.
