Quickstart: Your First AI Assistant
Follow this guide to set up your first Nova assistant in just a few minutes.
Choose a voice
Select the right personality for your assistant from 16 AI voices — across three quality tiers:
- Natural voices — Warm sounding, universally usable
- Expressive voices — Emotional, studio-grade quality
- Enterprise voices — Fast, clear, ideal for high call volumes
Configure the greeting
The greeting is the first sentence callers hear. It plays automatically as soon as the call connects.
Example:
"Hello, this is Dr. Müller's practice. How can I help you?"
Customize the prompt
The prompt defines your assistant's entire behavior: how it responds, what information it shares, and how it reacts to different situations.
You have two options:
- Write it manually — Full control over every detail
- Use the AI generator — Describe your business and the AI creates the prompt automatically
Set up a phone number
Your assistant needs a phone number to be reachable:
- Buy a Nova number — Purchase a number directly in Nova
- Connect your own number — Via SIP trunk (3CX, Starface, Fritzbox, Easybell, etc.)
- Call forwarding — Forward your existing number to the Nova number
Set up tools (optional)
Extend your assistant with actions it can perform during the call:
Set up post-processing (optional)
Define what should happen automatically after every call:
You're done!
Your AI assistant is now ready for use. Test it by calling the phone number you assigned.
Tip: Start with a simple setup (voice + prompt + number) and expand step by step with tools and post-processing.
