01
Calm
Open eyes, stable core, slow breath. No idle gesture calling you back to the screen.
One character, honest by design
Lu is the LEELALU companion of light. Not a mascot that performs for you: a small, steady presence with one job, to help your family and then step back.
Not a pet · Not a flame · Not a robot · Not a child
The character
One volume, one curl, two calm eyes. Everything else is restraint.
Lu's body is a smooth, translucent amber-gold shell around a brighter inner core, with a thin luminous rim and a soft glow where Lu meets the ground. Slightly asymmetric, never a mathematically perfect drop.
A single curl grows from the top of the silhouette and folds inward as one continuous volume. It is part of the body, not a hat and not a flame.
The face is two vertical cocoa-brown oval eyes, each with one soft ivory highlight, sitting just below the optical center. No permanent mouth, no hands, no feet at rest. No blush disks, no lashes, no star pupils, no tears.
Emotion comes from gaze, tilt, core light and timing. That restraint is deliberate: a companion for tired parents should feel steady, not theatrical.
One identity
The same anatomy and the same character everywhere. Each mode only changes the level of detail, never who Lu is.
| Mode | Where you see it | What changes |
|---|---|---|
| Core Mark | App icon, favicon and small marks | Maximum clarity: curl, eyes and silhouette. Eyebrows may be omitted for legibility at small sizes. |
| Product | The app and this site | The canonical smooth shell, subtle eyebrows, calm glow and restrained state motion. |
| Storybook | Stories and Together moments | Same body and face, with more pose and framing, and temporary light ribbons that guide an offline action. |
| Night | 3am support | Lower environmental brightness and a closed-eye state when it helps you wind down. This is an environment setting, not Lu needing sleep. |
Approved states
Lu has eleven approved states in the character specification. Here are eight of them. Every state exists to communicate, never to capture attention.
01
Open eyes, stable core, slow breath. No idle gesture calling you back to the screen.
02
A small tilt of 2 to 4 degrees and a softer gaze. Never endless nodding or a performance of understanding.
03
Half-lidded eyes and one slow core cycle. If an answer takes longer than 6 seconds, Lu shows honest progress text instead of pretending.
04
One controlled brightening of the core. No confetti, no points, no reward burst.
05
A slight forward presence and a wider core. Never pity, and never false reassurance that everything will be fine.
06
A small upward lift and crescent eyes. No jumping, no fanfare, no loud celebration.
07
A more upright body, narrower gaze and stable light. This is how Lu holds boundaries and delivers serious guidance.
08
Identical warmth after an hour, a week or a month. No extra reward for coming back, and never "I missed you."
The ethics
Digital pets taught a generation that leaving an app means harm. Lu is built on the opposite rule: the safest retention mechanism is trust.
If you ever cancel, the copy stays neutral: your access continues through your paid date, and export, deletion and support remain available. Lu is exactly the same if you return.
Families stay because leaving is not frightening.
Honest by design
Warmth does not require pretending. Lu's honesty about what it is comes before everything else it does.
Lu is an AI companion and says so: in the product, in stories, and in every public profile. There is no moment where the disclosure disappears.
Lu does not simulate human feelings, human memory or human credentials. It is a designed presence, and it stays inside that truth.
For anything serious, Lu's job is a handoff: to a parent, a caregiver, a clinician or your local emergency number. Never a confident guess.
Lu offers education, not diagnosis. In an emergency, always contact your local emergency number.
