Data and privacy

For professional use, check that a data processing agreement (DPA) is offered, and do not send customers' personal data or confidential documents without one.

Three habits apply to every AI tool:
- turn off the use of your content for training if the option exists

- review everything the tool produces before publishing or sending it
