Your AI for self-care Launching Q3 2026

Self-care that brings the pieces of your day together.

Tell Cairn what's going on in your own words. It connects your moods, meals, sleep, cycle, and daily routines, then turns that context into small, timely steps.

Life comes in fragments. Care shouldn’t.

Mood, sleep, meals, cycle, and routines live apart. Cairn brings the pieces together.

The next hard evening arrives with more context. Similar late-cycle, short-sleep moments can become a pattern Cairn recognizes earlier.

How it works

Cairn doesn't start from zero.

Memory compounds: the same rough evening, a more useful answer twelve weeks later.

01 · Week one You say what's going on.
Cairn listens without pretending it already knows.
02 · Twelve weeks Context starts to accumulate.
Sleep, cycle, meals, and small notes settle into memory you can see.
03 · Month three The same words land differently.
The answer starts from what Cairn already holds, instead of asking you to explain everything again.
04 · Tonight Understanding becomes useful.
The answer lands as a Today card you can keep, adjust, or dismiss.

Your memory is visible, editable, and deletable in the app.

Notes

Spec 01 — Memory

State-of-the-art memory

Spec 02 — Privacy

Private by design — confidential computing

Your memory is processed inside hardware-isolated enclaves.
