Lumma

An AI-native diary app for your inner reflections

Journal freely. Reflect deeply. Powered by AI.

As a heavy Obsidian user, I love journaling. But Obsidian’s mobile experience is lacking, especially for AI-based plugins. That’s why I built Lumma with Flutter—to create a seamless, mobile-first journaling experience.
