Introduce it as a tool not an answer machine
brainstorming is a good idea, you can also have it explain troubleshooting steps for students that currently do not have a functioning program it can also explain data structures that they are not confident about and show examples in cases where they are best used if there really stumped they can ask for an answer but make sure they understand why it was not working
You can also state that the tool won’t be available during high scoring tests to add incentive to learning concepts and topics while making other assignments with the tool worth less points
