Fade in on a phone lying on a wooden desk beside a coffee cup. It rings with an incoming WhatsApp audio call from "Hermes", with Decline and Accept buttons.
- At 0:03
Caption: "Hermes is calling." A small label above it says this is new in the Hermes plugin catalog.
- At 0:04
The call connects and a timer starts. Hermes: "Morning. Quick heads-up before your day starts. Your 10:30 with the design team just moved to 2." The words appear as a caption card beside the phone.
- At 0:11
You: "Ah. Okay. Can you push my gym session to 5, then?" The line appears in a caption card labeled "You".
- At 0:14
Hermes: "Done. Gym is at 5. I'll send you a recap in the chat." A status chip reads "Moving your gym session", then turns into a green check with "Gym moved to 5:00 PM".
- At 0:18
You: "Perfect. Thanks."
- At 0:20
Hermes: "Talk soon."
- At 0:22
The screen shows "Call ended". A WhatsApp notification from Hermes reads "Call recap: your 10:30 with the design team moved to 2:00 PM. Gym moved to 5:00 PM."
- At 0:25
Title card for the plugin "hermes-whatsapp-voice": "Live calls over regular WhatsApp." Below it: "A community plugin. No business account needed."
- At 0:27
Three cards: "Only calls you." (it can only ring the owner number you set), "Works mid-call." (ask for something and Hermes handles it while you talk) and "Recap after." (a short summary lands in your WhatsApp chat).
- At 0:31
End card: "@HermesWatcher" on a dark background.
