Sai — people & patterns

Register the people who matter, log what happened between you, and let AI analyze their traits, your patterns, and where things get stuck.

Why does that person drain you? AI-Powered Relationship & Psychology Diary, 'Sai'

It’s hard to understand why a different "you" comes out depending on who you're with, isn't it?

Sai is not just a standard mood tracker. It's a relationship and psychology diary where you record interactions with family, partners, coworkers, or friends, and our AI analyzes the underlying patterns in those relationships.

Why Choose 'Sai'?

Standard Diary Apps: Focus merely on "How did I feel today?"

Sai: Dives deeper into "Why did I react this way with this specific person?" to uncover the root context of your relationship dynamics.

Key Features

Register Relationships Add the people you want to understand better. Categorize and manage them systematically by type (e.g., family, partner, boss, friend).

Record the Context Log events, conversations, conflicts, and happy moments within the context of the relationship. The key is capturing the dynamic of the interaction, not just a list of feelings.
