How it works

Two audio channels in. Nothing out that you didn't approve.

Companion captures your microphone and your system output as two separate streams, so it always knows which side of the table said what. Everything else is built on that split.

Capture

Your mic and Windows loopback audio as two 16 kHz streams. No meeting bot, no extra participant, no invite to accept.

On your machine

Transcribe

One multichannel Deepgram Nova‑3 socket returns a per-speaker transcript, and keeps up when the room switches language mid-sentence.

Deepgram

Measure

Talk share, silence and monologue length are computed locally from the diarized turns. Nudges fire on your playbook's own thresholds.

No model calls

Coach

Claude reads a rolling window of the conversation and returns one best next move, the playbook card that fits, and a running summary.

Claude Haiku

Close

A debrief written in your playbook's sections, filed next to the transcript, the recording and the tasks it found.

Claude Sonnet

Built to be discreet

The quietest tool in the meeting.

Most meeting AI announces itself, joins as a participant and uploads the recording to somebody else's cloud. Companion does none of that. It is a window on your own desktop, private to you the way your notebook is.

The main window is where you work. A mini overlay is opt-in from the tray when you want it floating above the call: always on top, click-through until you reach for it, and shrinkable to a single line.

Invisible to screen shares

Companion's windows are marked as protected content, so your prep and your coaching never land on the screen you are sharing, recording or casting.

Recordings never leave your machine

Each call writes its transcript, brief, summary, tasks and recording to a folder under %APPDATA%/companion/sessions. The recording stays on your PC; your account holds only the history and transcripts that make your meetings searchable.

Read-only when it looks things up

Research runs through an explicit read-only allowlist that fails closed. Companion drafts; it never sends on its own.

Nothing executes unattended

Suggested actions arrive as chips you arm, edit and run yourself. A drafted Slack message takes two deliberate clicks to send, and can only be sent once.

During the call

One thing to do next, not a dashboard to read.

The coach ranks everything it is seeing and shows you the single most useful move, badged so you know what kind of move it is. Dismiss it and the next one takes its place.

Ask Do next Answer now Respond Watch Make space Join in Playbook

A transcript that knows the room

Both channels are diarized separately, so a colleague who speaks up on your side becomes their own voice rather than being folded into you. The first mic voice becomes "You".

Talk balance, and a nudge when it slips

Your share and theirs, over the last five minutes. Run past your playbook's ceiling or hold the floor too long and you get one line: hand it back, or jump in.

Ask about any line, mid-call

Tick a transcript line, a note or a task and ask about it. "Ask" answers from the meeting itself; "Check sources" goes and looks it up in what you have connected.

Correct it in the moment

Fix a misheard line or add a caveat and Companion treats your note as authoritative from then on. Originals are kept, edits are marked.

Every turn is tagged as it lands

decision commitment contradiction objection risk assumption question asked you fact ask

Each tag carries a one-line note. A commitment carries who owns it and when it is due, and says so when either is missing. A contradiction names what it contradicts earlier in the same conversation, which is how you catch the number that moved between slide four and slide nine.

And a suggested next step, at most one per turn

Chips are proposals. Click one and the instruction lands in the dock, editable, with an Execute button. Companion suggests first and waits.

Playbooks

A different meeting deserves different coaching.

A playbook decides what "too much talking" means, how long a monologue can run, what the coach watches for, and which sections your debrief is written in. Five ship with Companion.

Playbook	Built for	Your talk ceiling	Monologue cap	Debrief sections
General	Any meeting or call	70%	120s	Summary · Decisions · Action items · Open questions
Sales	Sales calls and demos	65%	90s	Summary · Discovery learned · Objections handled · Action items · Follow-up email
External / Negotiation	Vendors, banks, advisors, partners	60%	90s	Summary · Terms discussed · Commitments by side · Action items · Open questions
Internal / MBR	Management meetings, MBRs, leadership syncs	75%	150s	Summary · Decisions · Action items · Risks raised · Open questions
1:1 / Interview	1:1s, interviews, coaching conversations	40%	60s	Summary · Themes · Concerns raised · Follow-ups

The Sales playbook also ships knowledge cards that fire on what was actually said, including Objection: Too expensive, Competitor mentioned and a Pricing structure card you fill in with your real numbers. Everything is editable in the app: goals, context, the guidance prompts, the talk-time guardrails and the debrief sections. Save a playbook and it applies to the next meeting you start, never to one already running.

Who it’s for

One coach, a different job in every seat.

The pipeline never changes — two audio channels, a playbook, one best next move. What changes is what your role needs caught before the meeting ends.

For sales

Win the moments a recording only explains.

Prospects speak more freely when no bot sits in the participant list. Companion keeps your discovery honest and answers the hard turns while the deal can still move.

Cards fire on what was actually said — Too expensive, Competitor mentioned — plus a pricing card you fill in with your real numbers.
A 65% talk ceiling and a 90-second monologue cap keep discovery a conversation, not a pitch.
The debrief lands with objections handled, tasks with owners, and a follow-up email already drafted.

For customer success & support

Walk into every renewal with the whole history.

QBRs, escalations and renewals run on what was promised months ago. Companion briefs you before the call and backs you up when claims start flying.

Ask "where did we leave this?" before you join — the briefing reads past meetings and your connected sources.
"We never received that" gets answered mid-call with the date and the thread, from read-only research.
The debrief records commitments by side, so what they promised sits on the record next to what you promised.

General & External / Negotiation playbooks See a claim checked →

For founders & C-level

The numbers agree, and the decisions have owners.

Board meetings and MBRs are where drift is most expensive. Companion holds the whole hour, so a moved number or an unowned commitment gets caught in the room — and the room stays private.

A contradiction tag names the earlier line it disagrees with — minute six against minute twenty-two.
A commitment without an owner or a date gets flagged before the meeting ends.
No bot joins, the windows stay invisible to screen shares, and recordings stay on your machine.

Internal / MBR playbook See the number that moved →

For finance & procurement

They negotiate weekly. You no longer do it alone.

Vendor renewals, bank terms, advisor calls — the other side does this for a living. Companion levels the table and keeps every term on the record.

Concessions get isolated as they land: what does the 7% cover that the 9% did not?
The debrief separates terms discussed from commitments, side by side.
The transcript follows the room even when it switches language mid-sentence.

External / Negotiation playbook See a bilingual negotiation →

For managers & recruiting

1:1s and interviews where you actually listen.

The meetings that shape your team are the ones nobody measures. Companion caps your share of the air and hands you the themes afterwards.

The 1:1 playbook caps you at 40% of the talking and 60 seconds per monologue.
"Make space" taps you on the shoulder when you are running the meeting alone.
Debriefs come back as themes, concerns raised and follow-ups — not minutes.

1:1 / Interview playbook See a 1:1 rebalanced →

For consulting & client work

Nine client calls a week, one defensible memo.

When the week is back-to-back calls, the detail is the deliverable. Companion files every call and finds the exact quote when you write it up.

Every call filed with its transcript, brief, summary and recording — on your own disk.
Ask your archive who said what; it comes back with the meetings and the exact quotes.
Click any line and the audio jumps to that second.

In the room

Seven meetings that went differently.

Same app, same two audio channels. What changes is the playbook, and what the conversation happens to need at that moment.

Quarterly review · sixteen minutes apart

The number that changed at minute twenty-two.

Long meetings drift, and nobody in the room is holding both figures at once.

Them06:12ARR is about 4.2 million on a run-rate basis.fact

Them22:04We are a little under four, run-rate, if you strip out the pilots.contradiction

Watch

This conflicts with the 4.2m ARR quoted at minute six. Ask which number goes in the deck.

What changed

Caught in the room, not in the minutes. A contradiction tag always names the earlier line it disagrees with, so you quote it back instead of half-remembering it. The number that ends up in the deck is the one you agreed on out loud.

Before you join

Walk in with the answer to "where did we leave this?"

Every meeting opens on a briefing chat rather than a blank recorder. Ask for exactly what you need and Companion goes and reads before the call starts.

Whatever the briefing turns up stays with the live coach for the rest of the call, and is filed next to the transcript afterwards. Ask again mid-meeting and the answer arrives with the conversation as context.

BriefingMeridian renewal review

What happened last time, and what is still open?

You met Dana and Marc on 21 May. Two threads never closed:

Audit-trail coverage, raised in the security review. No answer was ever sent.
Pricing pushback tied to their board cycle rather than to the product.

Their CRM record shows one renewal deal open this quarter, and Marc committed to introducing legal.

EmailSlackTeamsFiles3 past meetings

Afterwards

The follow-through writes itself.

End the meeting and the debrief streams in, written in your playbook's sections and faithful to what was actually said. Tasks arrive with owners and due dates already attached.

Everything stays yours to edit: rename the meeting, fix a line, reassign a task, add the context only you had. The recording plays back in the app, and clicking any line jumps the audio to that second.

Later, ask your own archive. Search the words, or ask Companion about a decision, a commitment or a moment you half-remember, and it comes back with the meetings and the exact quotes.

Summary

Renewal is live but gated on audit trails, not price. Dana needs a board-ready answer before March.

Objections handled

Price framed as board optics; reframed onto the included SSO work.
Alternative vendor raised but not named.

Action items

Questions

The questions to ask first.

Does a bot join my calls?

No. Companion listens from your own machine — your microphone and your system audio — so it works with Teams, Zoom, Meet and softphones without joining the call, without an integration, and without another face in the participant list.

Can the other side see it?

No. Companion is a window on your own desktop, and its windows are marked as protected content, so your prep and your coaching stay invisible to screen shares, recordings and casting.

Where do my meetings live?

Recordings stay on your PC, one folder per meeting, next to the transcript, brief, summary and tasks. Your account holds the history and transcripts that make your meetings searchable from the web. Power users can run entirely on their own Deepgram and Anthropic keys instead — those calls go straight to the providers with nothing in between.

What does it cost?

Companion is free while in early access. A free account includes transcription and AI coaching hours every month — no API keys to create, no card to enter.

What about other languages?

Transcription runs in multilingual mode and follows the room, even when it switches language mid-sentence. The coaching, the summary and the debrief come back in the language the meeting was actually held in.

Does it run on Mac?

Companion is built for Windows 10 and 11 (x64) today. That is where its two-channel capture — your mic and the system audio, kept apart — comes from.

Can it send anything without me?

No. Companion drafts; you send. When it looks things up, the research runs through an explicit read-only allowlist that fails closed, and a drafted message takes two deliberate clicks and can only be sent once.

Do I need to tell people I’m using it?

Recording and consent rules depend on where you and your participants are. Companion is private to you, like your own notes — but using it responsibly, including any notice your jurisdiction requires, is yours to own, the same as with any recorder or note-taking tool.

Create your free account Download for Windows

Windows 10 or 11, x64. Sign-in requires a free account, which includes free transcription and AI coaching hours every month — no API keys to create. Power users can run on their own Deepgram and Anthropic keys instead; those calls go straight to the providers with nothing in between. Searching your email, Slack, Teams and files needs Claude Code installed with those tools connected; without it, briefings fall back to calendar and CRM context and say what they could not reach.

By the time the summary arrives, the decision is made.
