GIVE YOUR CHARACTER A REPLY VOICE
Separate personality from facts, start with drafts, and give uncertain questions a clear handoff.

The caption gets the conversation started. The reply should sound like the same character—and know when it does not have an answer.
Keep voice and facts separate
Voice is how the character speaks: short sentences, dry humor, a warm sign-off. Facts are what the reply is allowed to say: an approved answer, a link, a product detail, or a saved FAQ.
A personality prompt should not invent a price, a delivery promise or a policy. Write those answers separately and keep them current. If the information is missing, let the conversation come back to you.
Start with one useful keyword
Pick a keyword that makes sense in the post. If a dance clip offers the routine, “DANCE” is clearer than an unrelated code. Pair it with the exact message and link you want a follower to receive.
Comment-triggered private replies and direct messages have different platform constraints. The current comment flow can send an initial private text/link, with optional public confirmation. Rich cards belong in supported direct-message flows.
Use drafts to learn the boundaries
Review draft replies before relying on automatic delivery. Try a straightforward question, a vague one, an unsupported request and a question with no approved answer. Look for accuracy and a natural tone.
Keep a way to step in
Draft/Auto reply selects how replies are handled. Pause is a separate control. Keep both easy to find, and review the activity and held requests as part of managing the account.
Live replies are currently a limited, permission-gated pilot. Availability depends on the connected account, platform permissions and the applicable messaging rules. The landing-page conversation is an interactive example, not a live inbox.
