Private beta for macOS

Mrtn hears both sides of the conversation in any language, keeps you on your playbook and tells you the next best thing to say, while you say it. Then it writes the follow-up for you.

Agentic first

Built on MCP.
Both ways.

Mrtn plugs into your tools, and your AI plugs into Mrtn. One open standard, the Model Context Protocol, in both directions.

In

Mrtn uses your tools

Connect any MCP server: your CRM, calendar, email and docs. Mid-call, Mrtn looks things up on its own; anything that changes data waits for your click.

Out

Your AI uses Mrtn

Mrtn is an MCP server too. Your AI app searches your calls, reads transcripts, summaries and playbooks, and labels or shares a call when you ask. It sees only what you can see.

How it works

Before, during and after the call.

Mrtn notices when a call starts in Zoom, Teams, Meet, Webex or a Slack huddle, and stops when it ends. Everything in between is taken care of.

How Mrtn works, step by step

Features

Everything a great coach
would do. Live.

Any language. Even mid-sentence.

60+ languages with code-switching and speaker labels. Your playbook terms, competitors and attendee names are boosted so they come out right.

  • ENCan we start the pilot in March?
  • NLJa, maar dan wel met het hele team erbij.
  • FREt le support, il est disponible en français ?
  • DEKlingt gut. Schicken Sie uns das Angebot.

Both sides. No bot.

Your microphone and the call's audio, captured right on your Mac. Nobody has to let a notetaker into the meeting.

You
Them

Your playbook, in plain YAML.

Talking points, questions, MEDDICC or BANT, objections and battlecards. Keywords tick items off instantly in any language; Mrtn catches the paraphrases too.

talkingPoints:
  - text: Live alerts, set up in a day
    keywords: [live alerts, "live meldingen"]
battlecards:
  - competitor: Haulio
    weaknesses: [No live tracking API]
objections:
  - name: Too expensive
    triggers: ["te duur", "trop cher"]

Acts in your tools, with your say-so.

Connect your CRM, calendar, email and docs through MCP. Lookups run on their own mid-call; anything that changes data waits for your click.

Your Limitless Pendant, back at work.

Meta bought Limitless and its app is gone in Europe. Mrtn connects your pendant to your Mac over Bluetooth, and the recordings you choose become in-person meetings, transcribed, summarised and scored like your calls.

Use your pendant with Mrtn

No bot joins your call. Mrtn listens from your Mac, the way you do, and speaks up only when it helps.

Privacy

Your calls
stay yours.

Your organisation decides what is shared and how long it is kept. No bot joins your calls, and Mrtn's servers never store your audio.

Read the privacy policy

  • Audio is never stored on our servers

    It streams straight from your Mac to transcription in the EU. Recordings stay on your Mac.

  • Kept in the EU

    Transcripts, summaries and playbooks are stored in the European Union.

  • Shared on your terms

    Transcripts, summaries and follow-ups stay yours until you share a call with your team. Mrtn asks after each call.

  • Recordings that expire

    Set a retention period and old recordings are deleted automatically.

  • Consent, built in

    Playbooks can remind you to ask for consent before recording, where the law requires it.

  • GDPR by design

    A data processing agreement, a public list of sub-processors, and export or erasure of anyone's data on request.

FAQ

Good questions.

Does Mrtn join my meeting as a bot?

No. It runs on your Mac and records your microphone and the call's audio directly, so there's no extra participant in Zoom, Teams or Meet.

Which call apps does it work with?

Zoom, Microsoft Teams, Google Meet, Webex, Slack huddles and more, such as GoTo Meeting, RingCentral, Aircall, Dialpad, FaceTime and Whereby. Mrtn notices when one starts using your microphone, asks whether to record (or just starts), and stops when the call ends.

Which languages does it understand?

More than 60, including calls that switch between languages mid-sentence. Coaching and summaries come in the language you prefer.

Does Mrtn record audio, and where is my data kept?

Recordings stay on your Mac. Live audio streams straight from your Mac to transcription in the EU, and our servers never store it. Transcripts, summaries and follow-ups are stored in the EU, and shared with your team only when you choose to.

What do I need to run it?

A Mac with macOS 14.2 or later, Apple silicon or Intel, and an invitation from your organisation. Sign in once: no API keys, nothing to configure.

Is it legal to record my calls?

That depends on where you and the people you call are. Many places require everyone's consent; playbooks can remind you to ask before Mrtn starts recording.

Does Mrtn work with the Limitless Pendant?

Yes. Mrtn connects to your Limitless Pendant over Bluetooth and transfers its recordings to your Mac, and the ones you choose become in-person meetings: transcribed, summarised and scored like your calls. You need no Limitless account, and nothing goes to Limitless or Meta. mrtn.tech/limitless-pendant has the details.
