AI Call Screening

Unknown callers are screened by our AI assistant so you don't have to answer spam.

Let in what matters

Important calls are automatically connected through so you never miss what's real.

Private by design

Your contacts and call data are never sold. We protect your privacy like it's our own.

Watch it work

Screendoor picks up so you never have to.

Every unknown caller meets a natural-sounding AI that asks who's calling and why. It decides in seconds, and your phone only rings for the ones worth your time.

Spam calls, silently handled. Your phone never lights up.
Real callers, pushed through as a normal call, with who's calling and why.
Missed something? Screendoor takes a message and transcribes it into your call log.

The phantom-number model

A screener that works on every call, not just the ones iOS allows.

Your carrier quietly forwards calls to Screendoor first. Your real number stays silent until Screendoor decides a call is worth it.

STEP 01

Someone calls you

They dial your normal number, exactly like always. Nothing changes for them.

STEP 02

Your carrier forwards it

A one-time setup routes calls to your private Screendoor line, before your phone rings.

STEP 03

Screendoor screens it

The AI answers, figures out who's calling, and silently handles spam on the spot.

STEP 04

Only real calls ring

Legit callers come through as a normal call with full context. Everything lands in your log.

What you get

Quiet by default. Smart when it matters.

Silently handled

Spam hits a dead line. No ring, no voicemail, no trace. It just doesn't reach you.

Contacts always ring

People you know skip screening entirely and ring straight through, matched on-device.

Natural AI voice

Callers talk to a real-sounding assistant. Pick its voice and personality.

Transcribed messages

No answer? Screendoor offers to take a message and writes it into your call log. Never recorded.

Federated spam intel

Every screened call sharpens a shared spam signal that protects the whole network.

Shields & rules

Silence anonymous callers, block international, trust a business by name, set quiet hours.

The network effect

Every call your screener answers makes everyone safer.

Screendoor keeps an anonymous, shared reputation for the numbers it screens. Look up any number and see how the community has experienced it. Then let Screendoor handle the rest.

Questions

Frequently asked.

Do callers know they're talking to an AI?
Yes. Screendoor introduces itself as an AI assistant and tells callers the conversation is transcribed. Honest screening is part of why spam gives up so fast.
What happens to spam calls?
They get hung up on, silently. Your phone never rings, and the attempt shows up in your call log with the AI's verdict and a summary of what the caller wanted.
Will people I know get screened?
No. Your contacts and trusted callers ring straight through like normal. Matching happens on your phone, so your address book is never uploaded.
Does Screendoor record my calls?
No. Screening conversations are transcribed, never recorded. You get a text summary and transcript in your log, and there's no audio stored anywhere.
Do I need a new phone number?
No. You keep your number, and callers dial it exactly like before. A one-time carrier-forwarding setup quietly routes calls through Screendoor first.
