About
Feelings between people are rarely simple.
Sai is an AI relationship journal designed to help you track your emotions for each person, notice recurring behavioral patterns, and reflect on who you are within every bond.
Add the people who matter to you—friends, partners, family members, or colleagues. The exact same situation can feel completely different depending on who shared it with you.
■ Who is Sai for?
• Anyone experiencing relationship stress, emotional exhaustion, or communication fatigue
• People who want to discover their relationship attachment styles and coping mechanisms
• Those who find traditional journaling tedious and prefer quick, intuitive mood logging
• Anyone seeking a safe, confidential haven to express unspoken emotions and receive warmth
■ Journal for Each Relationship
Capture your daily mood, core emotions, bodily sensations (like tension or chest tightness), and self-protective responses. Write a quick one-tap check-in or a deep journal entry at your own pace.
■ Emotional Timeline & Visual Patterns
Review your history and recent mood changes for each specific person. Discover when you drew closer or drifted apart, and identify situations that repeatedly trigger your emotions.
