A little less note-taking.
A lot more conversation.

Detect the call. Follow the words. Know who said what. Explore the meeting tools in Brain for Mac and for Windows.

Mac: The call starts.
You choose what follows.

Brain notices Zoom and Microsoft Teams calls on your Mac and offers to record from the menu bar. In Settings › Recording, choose whether Brain asks you first or starts recording on its own. Asking first is the default.

Tell everyone before recording. These screens come from a test copy of the current Mac app filled with sample content, not from a real call.

Windows: The call starts.
You choose what follows.

Brain detects Zoom and Microsoft Teams calls. In Windows Settings, choose whether to record automatically, ask first, or leave recording to you.

Tell everyone before recording. Recording a real call through a real microphone has not been tested yet in this Windows preview.

Mac: The conversation,
in front of you.

Follow the live transcript while you listen. Switch between Live and Readable text, watch your microphone and the call audio separately, pause the scrolling, or ask the meeting helper for context.

Live text is provisional. Transcription speed and availability depend on your Mac and setup.

Mac: Who said what,
with context.

Read the saved transcript by speaker, play any passage, and rename, swap, or merge a voice in place. Unidentified voices stay separate until you decide.

A voice match is different from a confirmed identity. Check names and correct them when needed.

Remember the people.
Not just the words.

Listen to a clear passage. Confirm who it belongs to with one press: the suggested name, Me, someone else, or Skip. Saved voices help Brain recognize people in later conversations.

Build on the voices you have already confirmed, meeting after meeting.

Voice matches still need your judgment. Uncertain or new voices may remain unnamed.

Good conversations
deserve a next step.

Read a meeting’s summary, keep the decisions you agree with, and find every next step in one to-do list. Ask a question, check its source, and keep the next steps you agree with. Keep the conversation useful long after the call.

A thought.
A shortcut.
Your words.

Brain Speak turns your voice into text in the app you’re already using. Hold your shortcut, speak, and release; Brain types the words where your cursor is and keeps a history you can paste again. Choose your shortcut and activation mode, then keep your recent dictations close.

These Mac screens show Settings › Speak, the Speak History panel, and the floating Speak bar while it listens. Speak needs microphone and Accessibility permission. The dictations shown are sample content, and the leftover “Enable Accessibility to use Speak” warning is a quirk of the test copy used for the screenshot (about these screenshots).

These Windows screens show the shortcut, the dictation history, and the recovery controls. Typing into other apps is still being checked in the preview.

Works with your tools.
On your computer.

Brain’s command-line tool brings approved meetings, transcripts, and decisions into the tools you use. Any agent or app on your computer that can run terminal commands can work with Brain.

Or connect a tool that speaks MCP (the Model Context Protocol) straight to Brain’s own server on your computer.

Brain shares only the meetings you have approved, in the scope you pick. Whether that text leaves your computer depends on which AI model your own tool is set to use.

On your computer.
On your terms.

Your recordings and notes stay in your own account on your computer. Speech, summaries, and questions can all run on your computer once the tools have downloaded.

You choose whether to connect an online service. Connected services and agents may receive the text you share with them.
