Same call. Three very different endings.

A buyer calls at 2:14 while you're in a showing. At 3:02, you check your phone.

CallerWe're thinking of selling. Could someone tell us what the house is worth?

Your AI employeeHappy to set that up. An agent can come by Thursday at 4 for a free valuation. Does that work?

Honest with your callers. Clear with you.

It never leaves a caller stuck, and you always know what happened.

It knows when to hand you the call.

A caller who wants a person, or whom it can't help, is put through to you. If nobody picks up, it takes a message and says plainly that someone will call back.

Questions, answered.

Something else? Ask us.

Do I need to be technical?

No. You tell Nerro what your business does and what the employee should handle. Nerro writes the behavior, rules and hand-off settings for you. Advanced settings exist later, but you never need them.

What happens when the AI can't help?

It transfers to a person, or takes a message and says plainly that someone will call back. It is set up to never leave a caller stuck and never to claim something happened when it didn't.

Are calls recorded?

Nerro doesn't record call audio. It keeps a text transcript of each call so you can see what happened, and deletes it after the period you choose (30 days to 2 years). Callers are told at the start: every greeting says "This call is transcribed."

Is it legal for an AI to answer my business calls?

Generally yes, but disclosure and consent rules vary by state and country. Your AI employee introduces itself as an AI assistant on every call, Nerro doesn't record audio, and it only calls back people who asked to be called. Check your state's rules with a lawyer before you go live.

Will it sound like a robot?

Listen to the voice sample at the top of the home page: that's one of the voices your employee can use, and you pick from dozens. The goal is natural, turn-taking conversation, not a phone-tree menu. Voice quality depends on the speech provider behind it, and Nerro is built so that provider can be swapped without rewriting the employee, so quality improves over time instead of being locked in on day one.

How is this different from an answering service or IVR?

An IVR makes callers punch through a menu; a human answering service can't see your calendar. Nerro's AI employee does both at once: plain conversation, plus checking real availability, capturing the caller's details and booking the time, instead of just relaying a message.
