Redtie Phone · live today

A phone call
happens once.

Email you can re-read. A call happens live, in audio, and then it’s gone. Miss a word and you interrupt, or you guess. Redtie Phone makes sure you don’t lose it — live captions let you read the calls you take, and an AI assistant answers the ones you can’t.

How it works

Two things, one phone line.

Whether or not you pick up, the conversation comes back to you in writing.

When you take the call

Read it as it’s spoken.

Captions appear as the words are said — both sides, labelled by speaker. Read the address. Read the time. Read the name back. Nothing rests on catching it first time, and nothing rests on asking someone to repeat themselves.

The keypad stays on screen alongside the captions, so a phone menu is still navigable without hearing it.

When you can’t

An assistant actually answers.

Not a menu, and not voicemail — a real conversation. It finds out who’s calling, what they need, and the best number to reach them on, then reads the digits back to make sure it got them right.

You get a written summary, the callback number, and the full transcript.

Why it works this way

We built it for people who can’t hear the call.
It turns out to help anyone who can’t afford to miss it.

Around 466 million people worldwide have disabling hearing loss. For them a business phone number isn’t a way to be reached — it’s a barrier. That’s who Redtie Phone was designed for, and designing for them forced decisions nobody else makes.

Captions

Captions and keypad, together

Hiding one to show the other makes an automated phone menu impossible to get through. They stay on screen at the same time.

Alerts

Every alert is visible

Incoming calls are something you can see and feel, not only something you can hear.

Control

No call placed by accident

A tap on a contact never silently dials. You decide when a call starts.

Then we shipped it, and the people paying for it weren’t only who we expected. A business owner who kept missing calls and forgetting the details of the ones he took. An owner-operator whose whole business runs on getting an address and a pickup time exactly right. Different reasons. Same problem: a live, one-shot, audio-only channel loses things.

A work phone, not a personal one

Built for how a business actually takes calls.

Missing a call is the symptom. The job is running a phone line you can rely on — with the people, the records and the control a business needs behind it.

Screen it, then take it

Let the assistant pick up and watch the conversation as it happens. If it’s worth your time, take the call over mid-conversation — the caller carries on, and the captions carry on with them.

It knows who’s calling

When the number matches someone in your contacts, the assistant handles the call as a known contact rather than a stranger — and doesn’t ask them for details you already have.

Your real contact book

Microsoft 365, Google, and the address book on your phone — brought together in one place, kept in sync, not retyped into yet another system.

Up to five lines, one account

A business line, a personal line, a line for a second venture. Separate numbers with their own settings, all answered in the same app, billed on one account at $25 a line.

Every device, nothing missed

Mac, Windows, Android and the browser — live today, all in sync. Start a call at your desk, carry it out of the building. iPhone and iPad are in review.

A written record of every call

Transcripts and summaries for calls you take and calls you don’t. Searchable afterwards, so “what did they say the address was” has an answer.

Questions, answered.

What is Redtie Phone?

A business phone line with live captions on every call and an AI assistant that answers the calls you miss. Call in and out, read the conversation as it happens, and sync your Microsoft 365, Google and device contacts — on Mac, Windows, Android or the web.

How does the AI assistant work?

It answers and has a real back-and-forth with the caller — answering simple questions, screening spam, taking a detailed message with a callback number it reads back to confirm. You choose when it answers: Always, after no answer, or off. You can watch the conversation live and take the call over mid-conversation if it turns out to be worth your time.

Which platforms does it run on?

Mac, Windows, Android and any browser — all available today and kept in sync. iPhone and iPad are in App Store review.

Can I have more than one number?

Yes — up to five lines on a single account, each with its own number and settings, all answered in the same app. A business line and a personal line, or a line per venture. Each line is $25/month.

How much does it cost?

$25/month per line, with a 7-day free trial. Add more lines anytime at $25 each, up to five on one account. Cancel anytime.

Not an add-on. The whole phone.
