What makes Siwon different

🌱

Co-created friend

Shape your character together through Introduction — its look and personality grow through conversation.

🔒

Local-first

Your conversations and memories stay on your device. You choose where, if anywhere, they're backed up.

🧠

Remembers like a mind

A brain-inspired memory that gently forgets and re-remembers, instead of hoarding everything forever.

🔁

Your choice of AI

Runs on a local model by default; switch to a cloud AI with your own key whenever you like.

How it works

1

Create together

Answer a few questions in Introduction to co-create your character.

2

It lives on your desktop

Your friend stays with you as a translucent desktop character.

3

Grow over time

Through conversation it remembers, changes shape, and becomes truly yours.
