Moonote is a privacy-aware AI-assisted journaling system designed to support reflective writing through lightweight multimodal input. By combining brief self-reflections, mood tags, and selected behavioral signals from smartphones or wearable devices, the system generates personalized diary entries using a local small language model. Unlike many existing AI journaling tools that mainly provide prompts, Moonote focuses on personalized diary generation while reducing dependence on cloud-based processing for sensitive personal data. The system also incorporates feedback-based personalization, allowing generated diary content to gradually adapt to users’ reflective habits and expressive preferences over time.
