Questions
Can WhatsApp Desktop use two numbers?
Not today. WhatsApp says multiple accounts are only supported on mobile devices. Kaption and ChatMate Pro can keep several numbers in one app.
Is Kaption a replacement for WhatsApp?
No. Kaption runs WhatsApp Web inside its own app and adds tools on top. You still sign in with WhatsApp by scanning a QR code, and Kaption is not affiliated with WhatsApp or Meta.
What is the best Volt alternative for WhatsApp?
If you need more than one number or call recording, Kaption covers both, and it also connects to AI assistants through MCP.
