Offlog

Before you sleep, capture your day in a line.

Your entries become stars, forming a constellation that's uniquely yours.

Every night, you feel something. Joy, frustration, gratitude, anxiety — emotions that shape who you are. But they fade by morning. Offlog catches them before they disappear, turning your daily feelings into a living star map that reveals the hidden patterns of your inner world.

⭐ Your Life, Mapped in Stars

Write a single line about your day. Our AI extracts the people, places, and moments that matter most. Each keyword becomes a star. Over weeks, your stars connect, forming constellations that show what truly makes up your life.

You might discover that "coffee" and "mom" always appear together. That "work" connects to "anxiety" but also to "growth." That "music" is the star that never fades. Offlog doesn't tell you how to feel — it shows you what your life is actually made of.

🌌 A Living Constellation

Your star map isn't static. Stars that repeat grow brighter and stronger. Stars that fade from your life slowly dim and disappear. Connections between related keywords form glowing lines, creating clusters — your personal nebulae of meaning.

Drag stars around. Watch them drift back into gravitational balance. Pinch to zoom into your universe. Share a screenshot of your constellation with friends. Every star map is as unique as the person who created it.

📅 Emotion Calendar

See your entire month at a glance. Each day is marked with the emoji you chose — a visual timeline of your emotional journey. Spot patterns you never noticed: maybe Wednesdays are always tough, or weekends bring unexpected calm. The emotion flow chart tracks how your feelings shift across the month, drawing a line through your highs and lows.

🧠 AI-Powered Insights

Offlog uses AI to do more than extract keywords. It detects emotional tones (joy, calm, anger, sadness, and 6 more), maps them to colors using a 3D emotion model, and visualizes your emotional landscape as a radar chart.

Over time, the AI finds connections across different diary entries — linking "exam stress" from Monday to "relief" on Friday, or connecting "rainy day" moods across months. These cross-entry connections appear as subtle lines in your constellation, revealing deeper patterns you never knew existed.

🌙 Gentle Bedtime Reminder

Set your preferred time, and Offlog sends a soft nudge. Don't feel like writing? Tap the mic and speak. Voice-to-text captures your thoughts effortlessly. Or just pick an emoji and move on. There's no minimum, no pressure. Even a single emoji is a star.
