Does Grammarly train on what you write?
Whether Grammarly trains on your writing depends on how the account was bought. Individual accounts, and team accounts bought on Grammarly’s website, start with training on. Accounts bought through its sales team start with it off. Grammarly runs inside the apps where people type, so the setting matters more than for most tools.

Our take
For a firm of 15 to 200 people
Check the training control today, because many small teams bought on the website and never looked. Grammarly sees whatever is typed where it runs, so decide which apps it is allowed in.
