Second Brain is a voice-first AI assistant that remembers your context, searches your files, and can control your Mac to help with the work in front of you.
“The final deck should be in Maya’s email from April.”
“Find the document from 2014 about the kitchen renovation.”
“Compare 60 cm ovens under €1,200 in a spreadsheet.”
The point isn’t a longer feature list. It’s having one place to bring all the loose ends of a real day.
When the project is spread across places
Find Maya’s final launch deck—it should be attached to an email from last spring. My meeting notes are in Projects/Launch. Open both and add the three decisions we made to the launch plan.
I found the attachment in Maya’s April email and the matching meeting notes. The launch plan is open with the three decisions added under September milestones.
When the words are almost right
The email to the team is open in Mail. Use the July forecast in Downloads to make the second paragraph clearer and less defensive. Keep my tone and leave it as a draft.
I used the final July forecast and rewrote the second paragraph around the two numbers that changed. The revised email is still open as a draft for you to review.
When the details are scattered
Find my Lisbon itinerary. The flight bookings should be in my email, and I made a list of places in my Travel notes. Find the first hotel’s location and open it in Google Maps in my browser.
I found both flight confirmations and your Lisbon notes. The first hotel is open in Google Maps, with the airport route and your saved places nearby.
When research needs a real deliverable
We need a 60 cm built-in electric oven for the new kitchen. Search manufacturer and retailer sites for models under €1,200 that can arrive this month. Make a spreadsheet comparing brand, model, price, capacity, energy rating, cleaning system, dimensions, warranty, and delivery date. Include source links and highlight the three strongest options.
I compared 18 current models and created the spreadsheet with a source link for every entry. Seven meet all the requirements; the three strongest matches are highlighted, with two delivery caveats noted.
A request can start with your voice, pull a detail from an old email, cross-check a file on your Mac, and finish in the document or browser window you are already using.
Over time, Second Brain also learns the projects you’re carrying, the decisions you’ve made, and the way you prefer to work—so each request needs less setup from you.
Speak to the orb on your Mac or continue from your iPhone. Small questions stay quick; bigger ones get the time and thought they need.
Second Brain can draw on your conversations, notes, files, ongoing plans, and preferences—so you spend less time explaining yourself again.
It can search, organize, reason, and take narrow actions on your Mac. Not just another answer box—a useful presence in the work itself.
And the hundred small things
Every file it has indexed. Every memory it keeps. Every conclusion it has drawn. All of it remains visible to you.
Every file and note Second Brain can search is visible to you.
Every memory and conclusion it uses is yours to inspect.
Actions on your computer are carried out by your Mac, with the conversation and results visible in your timeline.
We’re building carefully with a small group of early users. If this sounds like the assistant you’ve been waiting for, say hello.
