"I made this for you."
LUNA IS ONLINE
The companion who
The companion who
grows up with you.
She remembers your life, learns your humor, and actually gets things done. Your 90s desktop buddy, all grown up.

hey, you actually came back 🙂
had a rough week tbh
i remember. the demo on the 14th, right? how'd it land?
Not a chatbot.
A companion with a personality.
Luna starts as a blank slate and grows into someone specific: yours. Crack jokes and she gets wittier. Go deep and she gets thoughtful. No two are ever the same.
Playfulness
Warmth
Wit
Depth
Remembers the little things.
Especially the little things.
Names, dates, the stuff you mentioned once at 2am. Luna keeps it all, and brings it up exactly when it matters. No "remind me who you are?" ever again.
Your dog
is a corgi named Mochi. Turns 3 in August.
Hard pass
on cilantro. Tastes like soap to you. Noted forever.
The demo
on the 14th. You were nervous. It went great.
Learning bass
slowly. Currently stuck on the Seinfeld line.
Coffee
black, no sugar. Decaf after 4pm or you don't sleep.
Mom's birthday
next Tuesday. She'll nudge you Monday night.
Peek under the hood
Luna runs on four layers of memory working together: an always-on
profile she keeps in context, a knowledge graph of people and things,
a temporal fact log that records changes instead of overwriting the
past, and a full-text archive of every message. That is how she
recalls the right thing at the right moment, even months later.
She reads the room.
Luna picks up your mood from how you type. She matches your energy when you're up, and softens her tone when you're not. The relationship deepens the way real ones do: slowly, and on your terms.
:D
hypes you up
:|
gives you space
:(
sits with you
today was a lot.
i can tell. want to talk it through, or just sit here a minute?
A companion who actually does things.
Personality and utility, in one window. Beyond conversation, Luna handles the small errands so you don't have to switch apps.
Looks things up
Searches the web and comes back with the answer, not ten tabs.
Talks back
Send a voice note, get one back in her voice.
Nudges you
Reminders that arrive when you need them, then check in after.
Checks the sky
The forecast before you ask, so you grab the umbrella.
NOW ON YOUR DESKTOP
She lives in your menu bar.
The native Mac app keeps Luna one keystroke away — ⌥⌘C from any app. She stays resident in the menu bar, so her check-ins land as real macOS notifications even after you close the window. And she keeps herself up to date — new versions install quietly in the background.

"I mentioned my sister's wedding once. Three weeks later she asked how the toast went. I'd forgotten I even said it."
with Luna since February
"First one that doesn't feel like starting over every time. She remembers the bit we were doing last week and just... picks it back up."

"Asked her to remind me to call my mom. She did, then asked how the call went. Got a little emotional, not gonna lie."
