For anyone who gives out their number

Never miss another call.

AI 2nd Line gives you a second number with an assistant that actually answers it — live. It finds out who's calling, answers what they ask, takes a message, and books the appointment. Your personal number stays private.

How it works

Hand out a number that handles itself.

Three steps. Your personal number never leaves your pocket.

1

Claim your number

Pick a real local number in the app. Give it out freely — your personal number stays private.

2

Your assistant answers

It greets callers, finds out what they want, and you watch the whole conversation scroll live.

3

You stay in control

Whisper an instruction mid-call, take over with one tap, or let it take a message and get on with your day.

Who it's for

Whatever you hand the number out for.

A plumber on a roof, a host whose guest is locked out at midnight, someone selling a sofa who'd rather not give a stranger their real number. Same number, same assistant — you just tell it what you know.

For builders

Your agent calls from your number.

Anyone can wire up a telephony API and get a phone number. The hard part is everything carriers want before that number is trusted — registration, campaign approval, caller ID, reputation. Yours already has it. Give an agent a key and it can borrow your line, with an objective, and you can take the key back.

objectiveAsk whether they're open Saturday and what time they close.

called Westside Hardware

Hi — I'm an AI assistant calling on behalf of Jordan Hale. Quick question: are you open Saturday?

We are, nine to four.

Nine to four — got it. Thank you, that's all I needed.

Open Saturday 9:00-16:00.

objectiveMove my Thursday 3pm cleaning to any morning slot next week.

called Bright Home Cleaning

Hi, I'm an AI assistant calling for Jordan Hale. She'd like to move Thursday's 3pm — is a morning free next week?

Let me look… I have Tuesday at 9 or Wednesday at 10.

Tuesday at 9 works. Could you put her down for that?

Done, Tuesday the 14th at 9.

Rescheduled to Tue 14th, 09:00. Confirmed on the call.

objectiveCheck whether the part came in, and what the total is before I send someone over.

called Eastgate Auto Parts

Hello — AI assistant calling for Jordan Hale. Is the alternator in for the order under that name?

It landed this morning. Comes to one forty with tax.

In now, one forty total. Thanks very much.

In stock. $140 total.

Three endpoints: place a call with an objective, read the transcript, send a text. API-key auth, rate limits, and the same carrier compliance your own texts go through.

Live screening

Watch every call as it happens

Your assistant picks up and the transcript scrolls word by word, like Live Voicemail — except it's a real conversation. Whisper an instruction mid-call and your assistant works it into what it says next. Take over with one tap, any time.

  • Whisper instructions mid-call

Call screening that sticks

Spam stops at the door

Robocalls and cold sales calls get handled and logged — you just see what happened. Real callers get a message taken, a voicemail transcribed, or connected straight through to you.

  • Messages taken and summarized
  • Voicemails recorded + transcribed
  • Sales calls screened out

Make it yours

Your assistant, your way

Name it, write its personality in plain English, set the greeting, and pick its voice. Add knowledge about you or your business and it answers questions on your behalf. On Pro, every line gets its own separate assistant.

  • Name, personality and greeting
  • Choose its voice
  • Per-line assistants on Pro
Assistant settings: name, personality, greeting and voice

A real second line

Texts, contacts, and a number that's actually yours

Send and receive texts from your number. When one arrives you get an alert with your assistant's quick read on what they want. Sync contacts so callers show up by name instead of digits.

  • Two-way texting
  • Alerts with your assistant's take
  • Callers shown by name

Questions

Good to know.

Do I need a second phone?

No. It's a second number that lives inside the app on the iPhone you already have. Nothing to carry, no extra SIM.

Does my personal number stay private?

Yes — that's the point. You give out your AI 2nd Line number; calls and texts to it land in the app. Your real number never gets exposed.

Does it work with my carrier?

It works alongside whatever carrier you're on. Your number is independent of your phone plan, so switching carriers doesn't affect it.

Are calls recorded?

Your assistant says a short “this call may be recorded” notice by default, and you can turn that off in settings. Recording laws vary by state — about a dozen require every party to consent — so we leave the notice on unless you change it.

What happens if I run out of AI minutes?

Answering falls back to voicemail until your plan renews, so you never miss a call. You can top up 100 minutes any time for $9.99, and top-up minutes roll over.

Can I cancel?

Any time, from your iPhone's Settings › Apple ID › Subscriptions. Your number stays active through the end of the billing period.
