## What is Sai?

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.

■ AI Relationship Insights in Just 3 Entries
With just 3 journal entries, Sai analyzes your positive and difficult interactions, recurring emotional dynamics, relationship distance shifts, and actionable ideas for healthier communication.

■ Understand Yourself with AI Persona
Explore how your behavioral patterns shift across different connections. Discover your defense mechanisms, emotional triggers, and personalized self-care recommendations tailored to your persona.

■ Thoughtful AI Comfort Grounded in Your Entries
Select a focus—reflection, looking back, regret, soothing comfort, or letting go. Sai generates empathetic messages contextualized by your actual journal entries.

■ Connect Through the Global Heart Mailbox
Send an anonymous note of gratitude, comfort, nostalgia, or quiet courage into the world, and receive a sincere note sent from someone across the globe. Built-in moderation, reporting, and privacy controls safeguard a kind and healthy sharing experience. (Account link required to post and read notes).

■ Private & Secure
Your privacy is our utmost priority. Easily manage your account, languages, AI credits, and data in one secure place.
