Forward your number
You keep the number friends, family, and businesses already have. Incoming calls forward from your carrier to a private routing line Clearline provisions and includes in the subscription. A second cellular plan is unnecessary.
The line between you and unwanted calls.
Everyone else is handled on your terms. Forward the number people already have. Rules decide who rings your iPhone. Unknown callers can land with an AI agent who keeps scammers talking, so you do not have to.

Turned on at 8:02 AM. Six calls have arrived since, so your carrier is forwarding.
How it works
Clearline is a premium personal switchboard. It stays ready, explains what it is doing, and gives you an immediate way to intervene.
You keep the number friends, family, and businesses already have. Incoming calls forward from your carrier to a private routing line Clearline provisions and includes in the subscription. A second cellular plan is unnecessary.
Rules run from the top and stop at the first match. Send a trusted contact to your iPhone, let Liam screen an unknown caller, ask Sydney to greet someone approved, send the rest to voicemail, or decline.
Listen to a live agent call without the caller hearing you. Take over when you want the line. Every call leaves a recording and a timestamped transcript you can review.
Home
Home answers three questions in this order: is forwarding on, how will the next call be handled, and is a call happening now. The mint stripe appears only when forwarding is on and Clearline is ready, so the stripe itself carries meaning.
Live call
When Liam or Sydney answers, the live card replaces the status band. You see the caller, the matching rule, the latest transcript, and two stable actions: Listen in on the left, Take over on the right.
Calls
Known contacts show a name. Unknown callers show a number, never a warning symbol. Destination and rule stay on one line, with time and duration in mono, so you can read a day of calls at a glance.
Rules
Each rule is a sentence. Taylor Reed is greeted by Sydney. Contacts ring your iPhone. Area code 248 goes to Liam. The last lane is locked, so every call has somewhere to go.
Agents
Screening agents answer in character, with saved voices and cached answers for a fast reply. A concierge greets approved contacts by name, reads your message once, and rings you if they ask to be put through.

Checked from top to bottom. The first rule that matches handles the call.

Listen in and take over
Listening is muted by design. The caller cannot hear you. Take over stays in the same spot on Home, on the Lock Screen, and in Dynamic Island, so your thumb already knows where to go.
02:14Recordings and transcripts
Agent calls leave a recording you can scrub and a transcript grouped by speaker. Cached answers are marked. Improvised replies are marked too, so you can see how Liam responded in the moment. Tap a line to play from there.
The social hook · example
Send a scammer to Liam. He stays in character and keeps the caller on the line while you stay off it. If the call is worth keeping, export a privacy-safe branded video with the number and names already stripped.
Example call · clock is sped up
Liam picked up. They have not hung up yet.
Hi, this is your bank. Can you confirm your date of birth?
I can try. It was a Thursday.
And the last four of your Social, for the file?
I used those for a pizza once. I can look.
Sir, are you the homeowner?
I water the plants.
Perfect. I just need a one-time code from your phone.
The phone is in the other room. I can wait.
How old are you, just to verify?
I'm 69.

Liam answers with saved lines and improvised ones. You are not on the call unless you choose to be.
Stay muted in the background, join if it matters, or let the recording wait for later.
Caller numbers, contact names, and your name come off first. Then you decide what else to hide.
Availability
Clearline is built for iPhone. The first commercial release is the United States on AT&T. Forwarding uses your carrier's existing call-forwarding flow. Clearline cannot see into iOS to prove the carrier setting, so Home is honest about what you requested, what you confirmed, and what incoming calls have shown.
