Drafted replies
Chatty can draft a reply to a customer message. It never sends one on its own — a person on your team reads the draft, edits it if it needs editing, and presses send.
Drafting a reply
Open a conversation in the inbox and ask for a draft. Chatty reads the thread and suggests a reply in the composer, where you can change every word of it before it goes anywhere.
Turn drafting on under Settings → Automations, where you can also choose the model and supply your own API key.
Nothing drafted is sent automatically. If nobody presses send, the customer gets nothing — which is why it is safe to point a model at a real customer conversation.
Answering without a person: keywords
For the questions you get constantly, a keyword is more reliable than a model. Bind a keyword to a published flow under Flows, and when a customer sends that word Chatty replies with a message you wrote and opens the flow — a booking form, an enquiry, whatever you built. That happens on its own, day or night.
See Test your flows for building and publishing one.
