The dynamic notch
The meeting starts. Your notch is already listening.
WhisperBrain detects Zoom, Meet, or Teams and expands around your MacBook notch with live transcription and one clear stop control.
Your second brain for meetings.
WhisperBrain captures conversations privately on your Mac, preserves the reasoning behind every decision, and saves it to your Obsidian vault.
A second brain, in your stack
Bring your vault. Choose your models.
WhisperBrain keeps the memory layer yours, while fitting into the tools you already use to think and build.
The cost of forgetting
The meeting ends. The context should not.
The expensive part of a meeting is rarely the hour on your calendar. It is the week you lose later, recreating a decision because nobody remembers what led you there.
“
What did we decide — and why?
WhisperBrain keeps the answer close to the conversation that made it. Not as another dashboard to maintain, but as memory you can find when the question comes back.
Meeting memorybuilt over time
A second brain for the room
Every part of the meeting, kept in context.
WhisperBrain notices the call, understands the conversation, and carries the important parts forward.
Knows who said it
Name a voice once. The voiceprint stays on your Mac.
It supports 40 languages
You never have to tell it which one.
Hindi, Tamil, Bengali, Urdu and Marathi live in the same vocabulary as English — so a sentence that starts in one and finishes in another stays one sentence.
The decision ledger
Not just what was decided. Why.
The part of a second brain nothing else builds: every decision filed with its date and the reasoning that produced it, searchable months later, in a markdown file you own.
It lives in your vault
Markdown in Obsidian, not another app to check.
Notes land in the Obsidian vault you already keep — as plain markdown you still own tomorrow.
On this Mac, forever
Free
Unlimited meetings, transcription and summaries, run on your own hardware with no cap and no card.

The transcript is only the beginning.
Most meeting tools give you a document to search. WhisperBrain gives you a memory to build on — one that gets more useful every time a decision comes back around.
It hears without joining.
No bot in the attendee list. No awkward recording announcement. Just your Mac listening to the call it is already playing.
It keeps the thread.
A decision from six months ago should not have to be made again because everyone forgot why it happened.
It writes where you work.
Real markdown in your existing Obsidian vault. Your notes remain yours, even if you stop using the app tomorrow.
The decision ledger
Because decisions don't happen just once.
A choice gets made on Monday, questioned on Thursday, and quietly changed three months later. The ledger remembers all of it — the decision, the reason, and what happened next.
Every decision, with a reason.Search “why did we pick Postgres?” and get the actual conversation.
Contradictions, called out.When a new decision conflicts with a standing one, you find out before shipping it.
Plain markdown, no silo.Decisions.md lives in your vault, linked to the meetings that made it.
Your meetings, connected
A meeting becomes a map.
Every conversation adds another node: a person, a project, a decision, a reason. Over time, the scattered moments turn into a living history of how the work got here.
Not a transcript archive. A second brain for the decisions inside it.
WhisperBrain
ObsidianThe feeling we're building
Leave the meeting with more than notes.
These are the reactions WhisperBrain is designed to earn: less rework, fewer repeated debates, and a clearer next step.
“I don't need another place to read what happened. I need to know why we chose it when the question comes back.”
“The best meeting note is the one that saves the next meeting from happening again.”
“A new teammate should inherit the reasoning, not just a folder full of summaries.”
Right where you look
From a quiet notch to a live transcript.
The dynamic notch appears when a meeting starts, shows the words as they happen, and gets out of the way when you finish.

The meeting stays on your Mac.
Audio and voiceprints never leave the machine. Recording, transcription, and speaker recognition run locally — on every plan, forever. Only transcript text can optionally go to the cloud when you ask WhisperBrain to extract a summary or decision.

Questions, answered
Nothing hidden in the fine print.
Does WhisperBrain join my meetings?
No. It runs on your Mac and listens to the audio already playing through it. Nobody sees another participant in the room.
What leaves my computer?
Audio and voiceprints never leave. If you enable cloud features, only transcript text is sent for summaries and decision extraction.
What happens to my notes if I stop using it?
They stay in your Obsidian vault as ordinary markdown. You keep every file, link, and decision.
Does it work with Zoom, Google Meet and Microsoft Teams?
Yes. WhisperBrain notices calls in Zoom, Google Meet and Microsoft Teams, whether they run in their native app or in a browser tab. It listens to the audio your Mac is already playing, so no bot needs to join.
How is this different from Otter, Fireflies, Granola or any other AI notetaker?
Most notetakers stop at a transcript or one meeting summary. WhisperBrain builds a decision ledger: what was decided, why, who said it, and what changed when the topic came back months later. It is local-first, invisible in the room, and writes to your own Obsidian vault.
How accurate is the transcription?
Accuracy depends on the recording quality, background noise, accents and overlapping speech. WhisperBrain is designed to capture clear meeting audio and identify speakers; for names, numbers and final decisions, it is still wise to give the generated note a quick review.
Which languages does it transcribe? Is it multilingual?
The Cloud tier supports 40+ languages, including mixed-language conversations. Local language support depends on the transcription model installed on your Mac.
What does it cost for a small team?
Local recording, transcription and diarization are unlimited on every Mac. The optional Cloud tier meters only the transcript-based inference used for summaries and decisions, so small teams pay for the speed they use rather than for stored audio.
How much setup is there?
Download the Mac app, grant audio access, and choose your existing Obsidian vault. Cloud mode removes the download and starts instantly; either way, there is no meeting bot to configure.
Can it handle an all-day session or a long conference call?
Yes. Local recording and transcription are unlimited. WhisperBrain can also stop automatically when the room goes quiet, which keeps long or loosely structured sessions tidy.
Does it integrate with Asana, Trello or Notion?
WhisperBrain's source of truth is plain Markdown in your Obsidian vault, not a proprietary workspace. You can link or move those notes into other tools, while direct integrations are not part of the current release.
Is my audio ever uploaded?
No. Audio and voiceprints stay on your Mac on every plan. If you turn on Cloud features, only transcript text is sent to external models for inference.
Does anyone in the meeting see that I am recording?
WhisperBrain never joins as a participant, so there is no bot in the attendee list or recording banner from WhisperBrain. Always follow the consent and recording laws that apply where you are.
Does it work offline?
Yes. Recording, local transcription and speaker diarization work offline. Cloud summaries and decision extraction need an internet connection because transcript text is sent for inference.
Does it work with my existing folder structure?
Yes. WhisperBrain writes real Markdown into your existing Obsidian vault and follows the folders and linking conventions you already use.
What happens if I stop paying, or stop using the app?
Your notes remain ordinary Markdown files on your disk. You keep the meetings, decisions, links and history even if WhisperBrain disappears tomorrow.
How does the contradiction checker decide something conflicts?
It compares a new decision with standing decisions on the same topic, looking for changed choices, incompatible terms or a superseded status. It surfaces the possible conflict for you to review; it never silently rewrites your history.
Can I use my own model provider?
Not in the current release. WhisperBrain keeps audio local and uses external models only for optional transcript inference; provider controls are on the roadmap.
