HOW IT WORKS

01

Write

Record freely. No prompts, no templates. Just your thoughts in your words.

02

Understand

AI reads context, not keywords. It understands the emotional weight behind what you write.

03

Discover

See how your emotions shift over time. Weekly and monthly reports reveal patterns you might miss.

WHAT IT DOES

01

Contextual Analysis

Not a mood score. 'A quiet evening alone' and 'being left alone' — different. It reads the difference.

02

Emotion Patterns

Follow how your emotions shift over days, weeks, months. The more it accumulates, the gentler the reports become.

03

AES-256 Encryption

Every entry, encrypted. So only you can read your diary.

04

Built with HUA

Built on our own framework. 12 npm packages, 100+ components, full motion system. Every layer is ours.

Emotion analysis grounded in research. How AI interprets feeling — we study it, we publish it.

KMS envelope encryption — encrypted before it touches storage.

Built on HUA Framework. 12 packages, all open source.
