Core problem
According to the American Psychological Association, journaling has been shown to reduce stress, improve mood, and enhance emotional processing. Yet many people struggle to keep up with traditional journaling due to time, effort, or emotional resistance.
I found that 91% of smartphone users globally use messaging apps daily (Statista, 2023), with WhatsApp leading the charge. This inspired me to build Luna an AI that fits into people's natural habits and spaces, making reflection feel more like a conversation than a chore.
The Problem We Wanted to Solve
Most journaling apps are either too rigid or too overwhelming, causing users to drop off after a few entries. They often lack emotional nuance and don't feel personal or responsive. The developer and I set out to build something different, simple, supportive, and emotionally intelligent. All powered on WhatsApp without installing another app for convenience.
