Before the call

Walk in prepared.

Five minutes before a meeting, Megaphone Bar briefs you: where you left off, what they care about, and three questions to ask.

Where you left off
  • They asked for annual pricing. You said you'd check with finance.
Ask today
  • Who signs off on the budget?
  • What would make onboarding a win in month one?
On the call

Listen. Jot three words.

Type as little as you like. Drifted off? Ask “What did I miss?” and get the last few minutes in three lines. Stuck? Ask for a good next question.

The admin is done.

When the call ends, your notes, action items and recap email are ready. The email opens in Mail for you to check. Action items go to Reminders in one click.

Hi Sam, thanks for today. We're set for Oct 14. I'll have the pricing deck to you by Friday…

Never drop a promise again.

Megaphone Bar hears “I'll send it by Friday” and remembers. Each morning you see what you owe, and what you're owed, across every call.

Your best call this week
is your next post.

Megaphone Bar finds the strongest idea in a call. Then it writes a reel script, a seven-slide Instagram carousel and a LinkedIn post, in your voice.

Highlight. Right-click.

In Mail, Slack, Notes or your browser, highlight text and pick a Megaphone Bar action. Fix the grammar, strip the AI slop or draft a reply. Megaphone Bar shows what changed. You copy it back.

Works in any app with the macOS Services menu. De-slop is built on SlopMonster by Jack Roberts (MIT).

18 engines on day one.

An engine is one job Megaphone Bar can do with a call, a person or some text. Use ours, or write your own in plain words.

Want one more?
It's one text file.

Write what you want in plain words. Drop it into ~/Baton/engines/ and it shows up in the pill.

~/Baton/engines/standup.md---
name: Stand-up
icon: list.bullet
inputs: [transcript, notes]
---
From this call, write three lines:
what shipped, what ships next,
and who is blocked on what.

Works the way you do.

Humans in the room, not bots.

Six people on the call, and no seventh square for a notetaker. Megaphone Bar listens on your Mac.

Your files.
Your Claude plan.

No new subscription and no API key. Megaphone Bar runs on the Claude plan you already pay for. Audio and transcripts stay on your Mac. Only what you hand off goes to Claude.

Where your data goes

Audio and transcripts never leave your Mac. When you run a hand-off, the transcript text goes to Claude under your own account, the same as any Claude Code chat. Nothing comes to us.

Is there a bot in my call?

No. Megaphone Bar listens on your Mac through your mic and your computer's sound. Nothing joins the meeting.

Which apps does it work with?

Any call that plays sound on your Mac: Zoom, Google Meet, Teams, Webex, FaceTime, Slack and WhatsApp.

How do I tell people I'm taking notes?

When you start, Megaphone Bar gives you a one-tap consent line to paste in the chat.

Never used Claude Code?

Onboarding walks you through it. Setup takes a few minutes.
