Fulcrum discovery call

  • Today
  • Dana Reyes

Pain Points

  • Pipeline lives in three spreadsheets and a part-time assistant
  • Proposal came in over budget, so finance wants the math
  • Follow-ups slip on days of back-to-back calls

Next steps

  • Send the cost comparison by Thursday
  • Book a demo with their ops lead

A live call with Dana Reyes, transcribing. Dana says the proposal is more than they budgeted and that they use spreadsheets and a part-time assistant. A coach tip suggests asking how many hours a week the spreadsheets take, then comparing that cost to the plan.

Call notes

Notes that write themselves.

Hang up and the report is already there: a summary, the key facts, follow-ups and anything you promised. Your CRM notes take seconds, not twenty minutes at the end of the day.

  • Summary, key facts and promises
  • Follow-ups ready to approve
  • Search every call by name, number or notes

Live coach

A coach on high-pressure calls.

Live captions for both sides, and the next thing to say on screen while they are still talking. Supafone spots the objection the moment it lands, suggests the reply, and Why shows the reasoning. Only you see it.

  • Live captions for both sides
  • Objection spotted, reply suggested
  • Pick a goal: book a meeting, close, renew

Live call with Dana Reyes, transcribing.

Dana: The demo was great. Honestly though, it is more than we budgeted.

Coach, price objection spotted. Suggested reply: Totally fair. How many hours a week go into the spreadsheets? Then compare that cost to the plan. Why: Price with nothing to compare it to. Anchor it to the hours they lose today.

You: Totally fair. How many hours a week go into the spreadsheets?

Dana: Probably ten, between me and Jess.

Live translation · Supafone+

Talk in any language.

When the other side switches to Spanish, Mandarin or any of 70+ languages, Supafone notices on its own and translates the call live. Their words, with your language right underneath.

  • Detects the language by itself
  • Original and translation, line by line
  • One switch to flip captions between languages
  • Notes and follow-ups stay in your language

Recordings · Supafone+

Recordings, on your terms.

Listen back at any speed, download the audio, or share it by Messages, Mail or AirDrop, with the notes right under the player. You decide who gets recorded: stop any call with one tap, or never record someone at all.

  • Listen, download and share
  • A never-record list for anyone
  • Stop recording mid-call, and delete what was kept
  • A Transcribing badge on every live call

The Call recordings list shows calls from today and yesterday. Opening Dana Whitaker’s call shows a player with Share and Download buttons, and playing it scrolls to the call notes: she wants the Pro plan for a 12-person team, key facts, follow-ups to send the quote by Friday and book a demo, and a promise to hold the launch discount.

Private by design

Your calls are yours.

The calls you make for work are full of things nobody else should hear. Supafone keeps it that way: nothing sold, no ads, no ad trackers, and you decide who gets recorded.

Put a client on your never-record list once and no audio of their calls is kept. Tap Stop on any live call and the recording stops, and what was recorded so far can go too.

AI calls · Supafone+

Your personal AI voice agent, done right.

Your personal voice agent phones businesses for you from your own number. It gets through the phone menu, waits on hold so you don’t, books what you asked for and comes back with one answer. Listen in or take over whenever you like.

You ask Supafone: Call three plumbers near me and find who can come today under $200. Supafone finds three plumbers nearby and calls all three at once from your own number. Mike’s Plumbing answers: they can come today at 3 pm for $165. Bay Area Drain Pros answers with a phone menu; Supafone presses 2, waits on hold, then hears they are full today and can come tomorrow at 9 am for $180. Rapid Rooter does not answer. Supafone answers: Mike’s Plumbing can come today at 3 pm for $165. You can listen in or take over any call.

Safari extension

Have your agent call, with the touch of a button.

Looking up a plumber, a dentist or a restaurant in Safari? Supafone puts a Call with Supafone button next to every Call button and phone number. Tap it and Supafone opens with the business and the likely goals already filled in from the page. One more tap and your agent is dialing.

  • Next to Google’s Call buttons, map listings included
  • The page comes along as context for the call
  • Works on any website with a phone number
Safari on an iPhone shows search results for a plumber near me, with business listings. Next to each Call button, a Call with Supafone button appears. Tapping it on Mike’s Plumbing opens Supafone with the business and number filled in, and suggested goals from the page. Tapping “Can someone come today, and what will it cost?” fills in the goal, and tapping Have Supafone call starts the call: Supafone’s AI rings Mike’s Plumbing from your number and starts talking.

In the app

Busy? It picks up, too.

Switch to Call with agent to send it out, or tap Let Supafone answer on an incoming call. It takes the message, and the notes are waiting when it hangs up.

  • Several calls at once, side by side
  • Listen in or take over any time
  • Missed calls answered, with notes

In Call with agent, the user types Bright Smile Dental as who to call and Book a cleaning next Tuesday morning as the goal. The Live calls list shows three dentists being called at once. The results screen then answers the question: Bright Smile Dental has the earliest cleaning, Tuesday at 9am, Dr. Lee is booked until the 18th, and Harbor Dental did not answer.

An incoming call from Dana Reyes shows Decline, Let Supafone answer, and Accept with coach. Tapping Let Supafone answer hands the call to the AI, with a banner saying Supafone is taking the call. Then the recording of another call that Supafone answered shows its notes: the caller asked about weekend hours and Supafone took a message.

    Sales repExample

    I don’t take notes on calls anymore. I hang up and Supafone has the summary, what they objected to, and the follow-up email already drafted. Last week it popped up the exact answer to a price objection while the guy was still talking.

FAQ

Questions, answered.

Will people see my real number when I call?

Yes. During setup Supafone confirms you own your cell with a short code. After that, every call you place from Supafone shows your own number, so people recognize who is calling.

Is Supafone private?

It is private by design. Supafone never sells your data, shows no ads, has no ad trackers, and doesn’t train AI models on your calls. Your account is walled off so only you can sign in to it, your data is encrypted in transit and at rest, and you can delete your account from the app. To caption, coach and write notes, calls are processed in the cloud by the providers listed in the app (such as Twilio, Deepgram and Anthropic), so Supafone is not end-to-end encrypted. Read the privacy policy.

Does Supafone record my calls?

By default, yes: Supafone records and transcribes your calls so it can coach you live and write your notes, and a Transcribing badge shows on every live call. You decide who gets recorded. Tap Stop recording on any live call (and delete what was recorded so far), or add someone to your never-record list and no audio of their calls is kept. Supafone gives a recording notice where the law requires one.

Which carriers does it work with?

Supafone works with the major US carriers, including Verizon, AT&T and T-Mobile, and most other carriers that support call forwarding. The app checks your carrier and shows you the exact steps. A few carriers, like Visible, can only forward every call rather than just the ones you miss.

Do I need a new phone number?

No. You keep your cell number. Supafone sets up your own Supafone number behind the scenes, and your cell forwards calls to it so they ring in the app.

How much does it cost?

Supafone is free to download and free to start, with free coached calls included. Supafone+ is an in-app subscription with a 7-day free trial for new subscribers. The price is shown in the app before you subscribe, and you can cancel any time in Settings.

Can the AI answer calls when I am busy?

Yes. Tap Let Supafone answer on an incoming call and the AI takes it. Calls you do not pick up are answered by your AI too, and you get the notes either way.

Is there a version for my business?

Yes. Supafone also runs AI phone agents for businesses, with a web dashboard for answering calls 24/7, booking appointments and following up on leads. See Supafone for business.
