Hi Product Hunt 👋 For a long time, journaling has been my way of reflecting on life. But I always felt that most journaling tools only help us store memories, not truly understand them. My background is in data visualization and data storytelling, and I’ve been deeply inspired by projects like Dear Data, which showed that personal data can be expressive, human, and even artistic. That idea stayed with me: what if the small fragments of our daily lives could gradually become a meaningful story? This led me to build Lumos Diary. Lumos is designed around a simple but powerful loop: Human → AI → Visualization → Human • People start with low-effort journaling, capturing small fragments of daily life. • AI then extracts structure from these entries — emotions, themes, and patterns. • A visualization system transforms this data into expressive, narrative forms that reveal rhythms and changes across time. • These visualizations help people reflect, reinterpret, and gain new insights, which naturally feed back into future journaling. Over time, this creates a positive feedback loop between reflection, data, and self-understanding. My hope is that Lumos can bring ideas from data humanism and personal data storytelling into everyday life — turning personal data into something meaningful, reflective, and deeply human. Instead of just recording life, Lumos tries to help you see the story behind it.
