While AI tools often generate output that appears authoritative and confident, these tools often don't show the process they used to create that content or the sources they based the generated content on. In fact, AI tools often fabricate imaginary sources that they claim were used to create the generated content.
When you upload material into an AI tool, it's often unclear whether the developer will retain that information, use it to train its AI tools, or even share this information with other users of the tool. Ultimately, if you want to keep information private, don't upload it into AI tools, such as when asking a tool to help improve your grammar and writing.
In addition to the above considerations, it's important to consider the broader impact that AI use has on individuals, society, and the environment.
