The line really comes down to what you're actually responsible for. If your job is to produce work that meets a standard - whether that's code, writing, analysis, whatever - and you're reviewing it carefully, catching errors, and taking accountability for it, then you're doing your job. You're using a tool. Using spell-check isn't fraud. Using a calculator isn't fraud. Using AI to draft something and then actually editing, fact-checking, and improving it is legitimate tool use. The key question is: could someone else in your role reasonably do this? If the answer is yes, then you're just more efficient than they are, and that's fine.
Where it crosses into real trouble is if you're *not* actually reviewing the output, or if your job specifically requires you to do the thinking and decision-making yourself and you're outsourcing that to the AI without engagement. Like, if you're a doctor prescribing what ChatGPT suggests without actually evaluating it, or you're a lawyer submitting AI drafts without catching the hallucinations - that's different. You're not doing the job. But if you're sitting there actually reading through what the AI produced, fixing mistakes, adding context, applying your judgment, and then standing behind it? That's work. You're the filter. You're the quality control.
The guilt you're feeling might just be that it *feels* too easy now, which is a separate thing. But easy doesn't equal wrong if the end product is solid and you're actually doing the oversight. If your employer cares about how you get there rather than what you deliver, that's a conversation worth having - maybe they want you doing the work manually for some reason. But if they care about output and you're delivering good output, you're probably fine. Just don't start skipping the review step because it's convenient.
