Answering reviews
Paste in the review, briefly say who you are and how you want to sound, and ask for a draft. Then finish it yourself with something personal, because guests can tell a standard reply from a real one.
Also works for that one unfair review you've been angry about for three days. Let the chatbot write the first version, and your reply stays polite.
Writing and translating
A job ad, an email to a group, your menu in English or German, a post about the new menu. Give it a few lines you once wrote yourself and the result will sound like you.
Have it rewrite rather than invent. Your rough draft plus a chatbot beats a blank page plus a chatbot.
Brainstorming your menu
Ask for ten ideas for an autumn dish with pumpkin, or variations on a dish that sells well. Nine will be nothing, but that one puts you on a track.
Any cost prices it produces are guesswork. Ideas yes, numbers no.
Drafting documents
House rules, an onboarding booklet, a phone script for reservations. Dictate what you know or paste in your loose notes, and have it turned into a clean document.
The messier your input is allowed to be, the more time it saves. Tidying up is exactly what this is good at.
