Describe what you actually do, in plain terms. The generator picks up on the themes in what you wrote — emails, spreadsheets, meetings, customers, whatever it is — and builds a job title and bio absurd enough that it could genuinely appear on someone's LinkedIn tomorrow.
Underneath it, in smaller print, is what you actually said. That's the point. The title changes. The job does not.
