Yes， I'm here. What do you want to talk about？
Your sentence "Are you there?" is already clear and natural for checking if someone is available or listening (especially in informal situations like calls or chats).
Possible improvements (depending on context):
1. More polite/formal: "Are you available?" (if asking if someone has time)
2. More casual: "You there?" (common in informal chats)
3. If checking a connection: "Can you hear me?" (for phone calls) or "Are you online?" (for messaging)
Tip: Your original sentence is fine for everyday use. Just match the tone to your situation (formal/casual).
