SMS Copilot: How AI Reply Suggestions Work
SMS Copilot is JustCall's AI-powered assistant that generates 2–3 reply suggestions based on the full conversation thread. It reads context — not just the latest message — to produce relevant, ready-to-send responses.
Available on: Team plan and above (AI add-on may be required)
How to Enable SMS Copilot
- Go to Settings → AI Features.
- Toggle SMS Copilot on.
- Open any SMS conversation with an unread incoming message — suggestions appear automatically above the compose area.
How Suggestions Are Generated
- A customer sends a message.
- Copilot reads the full conversation thread for context.
- It generates 2–3 suggested replies.
- Click a suggestion to load it into the compose field.
- Edit if needed, then send.
Copilot never sends messages automatically. Every suggestion requires your explicit action.
When Suggestions Appear
Suggestions appear when:
- You open a conversation with an unread incoming message.
- A new message arrives while you're viewing a conversation.
Suggestions do not appear when:
- The last message in the thread is from you.
- The conversation is closed or archived.
Tips for Better Suggestions
- Keep conversations in one thread — fragmented conversations across multiple numbers weaken context.
- Use clear subject lines in initial outbound messages so Copilot stays on-topic.
- Don't rely on it for legal, medical, or escalation messages — write those yourself.
