Your nerdy friend who actually pays attention and remembers.
Howdy, Alexi.
What are we digging into today?
Your life spaces
One intelligence, many roles
- Fitness coach
- Memory keeper
- Project partner
- Travel planner
- Study companion
- Thinking partner
What you can do
Point it at anything in your life
Talk it through, drop in a file, or just let it remember. It only ever reads what you give it, and never uploads anything.
Keep a life space for anything you care about
Remembers your goals and follows up on them
Chat with your own notes, PDFs, and spreadsheets
Quiet insights when something worth knowing changes
Looks things up on the live web when you need fresh info
Everything stored on your device, nothing uploaded
Ask your life
Ask about anything you've told it
Type a question the way you would say it out loud. Lumi checks what you've saved in that space and answers from it, not a guess.
- Plain English in, a real memory out
- Answers grounded in what you've actually shared
- Nothing invented, nothing forgotten
Nishiki Market's tempura stall, the one Aya mentioned when you two were planning routes last month. You saved it under "food to try."
Insights feed
An insights feed that only speaks when it matters
Lumi quietly notices progress and patterns in your life spaces and tells you when something real changes. No noise, just the handful of things worth knowing.
- Surfaces notable shifts on its own
- Every insight comes with the story behind it
- Quiet by default, useful when it speaks
You've hit the gym 4 weeks straight
That matches the streak you said you wanted back in week one. Rest days have stayed consistent too.
Second brain
A second brain for your life, not just your work
Open a workspace for anything you care about. Lumi asks about your goals, remembers what you tell it, and checks in like a thoughtful friend that actually kept notes.
- Separate spaces for fitness, travel, hobbies, and more
- Remembers your goals and follows up
- Everything stays on your device
Files
Connect a note, PDF, or spreadsheet and just talk to it
Drop in your trip notes, a packing list, or a journal entry and ask about it like a friend who already read the whole thing. Lumi reads it in place, so nothing leaves your machine.
- Notes, PDFs, and spreadsheets, understood end to end
- Answers cite the exact lines and pages
- Read only, and read locally
Three things unchecked: adapter plugs, the rain jacket, and yen cash. Everything else on the sheet is marked done.
First run
Up and running in three screens
Create your account on your device, and tell Lumi a little about you and what you want to remember. Then open your first life space, and land on a home screen with everything ready to go.
- Create an account, stored only on your device
- Tell it your name, goals, and what to remember
- Open a life space and start building memory
Welcome. What should I call you?
A name and a little context, so I know who I am helping.
Privacy
Everything stays on your device
Lumi never tells anyone anything, because it is basically mute. It cannot even see what you do out there, since everything runs locally on your device. Its memory lives in a database on your machine, and nothing is uploaded, ever. When you want a clean slate, you are one click away.
- Basically mute. It has no one to tell and no way to tell them
- Runs locally, so it cannot see anything you do elsewhere
- A local database, on your device and nowhere else
- Nothing is uploaded, ever
- Clear memory per space, or wipe everything at once
How it works
Three steps to grounded answers
Create an account, all local
Sign up on your device and bring your own frontier model key. Your account and its memory never leave your machine.
Open a life space and start talking
Spin up a space for Fitness, a trip, or anything you're working through. Lumi asks what you care about, then remembers it.
Get answers that build on what it knows
Every answer draws on what you've told it and your own files and notes, never a guess. Insights surface on their own when something changes.
A second brain that's actually yours
Download Lumi, open a space, and start talking. It stays yours, always, on your device.
