Frequently asked questions
Everything you need to know about NAG and how it answers your calls.
What is NAG?
NAG is a personal AI that answers your phone calls and text messages in your own voice. It holds real two-way conversations with callers, screens unknown numbers, blocks spam, and logs every call and text with a summary. You train it to sound like you, choose who it answers for, and take back over any call whenever you want.
How does NAG sound like me?
NAG creates a cloned voice from a short, clean recording of you. That clone is then used to speak on your calls in your own voice and natural cadence instead of a generic AI voice. The more clean audio you provide, the closer it sounds to you.
How do I train my voice?
You can train your voice two ways. Record clean audio clips in the in-app Voice Training Studio, or call your own NAG number with training mode turned on, which turns the call into a short interview that records your voice. Once you've collected enough audio, NAG builds your personal voice and starts using it on your calls.
Who will NAG answer for, and can I choose?
You're in full control. Add contacts and choose how NAG handles each one: answer in your voice, ring through to your real phone, take a message, or screen and text you the gist. For anyone not in your contacts, you set one default behavior. You can change any rule at any time.
Does NAG block spam calls?
Yes. NAG automatically detects and blocks known spam numbers so your phone never rings for them. Spam blocking is on by default and you can turn it off anytime in Settings.
Can I see what NAG said on my calls?
Yes. Every call and text NAG handles is logged with a summary and, when enabled, a full transcript. You can read exactly what was said and jump back into the conversation if you want to take over.
Is it legal to have an AI answer calls in my voice?
Laws on recording and AI calls vary by state and country, and some require telling callers they're talking to an AI or being recorded. You are responsible for following your local laws. NAG offers an optional AI disclosure greeting so callers know an AI is answering, but this does not replace your legal obligation to get consent where required.
Is my voice data private and secure?
Your voice recordings and your voice clone are stored privately and tied to your account. They are never sold and never used to clone anyone else. You can delete your voice and all of your data at any time from Settings, and deletion is permanent.
How much does NAG cost?
NAG offers simple monthly plans. See our pricing page for the current tiers and what's included in each. You can start with a free trial, no card required.
Does it work on iPhone and Android?
Yes. NAG works through your existing phone number and a web app, so it works on iPhone, Android, and any device with a browser. There's no app store download required, and callers never need to install anything.
