01 — journal
Write freely. Koro reads between the lines.
Every entry gets a mood tag and a semantic index — automatically, on your device. Search by feeling, not just keyword.
- mood detection
- 12 emotional states
- semantic search
02 — habits
Small routines. Real patterns.
Not every bad week has an obvious reason. Koro connects what you do with how you feel — habit by habit, week by week.
- habit tracking
- life areas
- weekly insights
03 — memory
Your past, searchable.
Memory tab surfaces what you wrote months ago, matched by meaning. Not a search bar — a recall engine.

04 — privacy
No one else needs to know. Not even us.
You'd tell a coworker about a headache. Not that you haven't slept right in months. Koro doesn't ask you to tell anyone — nothing personal ever leaves your phone.

Start tonight.
One short entry is enough. Koro takes care of the rest.
