LYLU - AI Diary & Mood Tracker

Speak instead of typing. LYLU is a voice-first diary that transcribes your daily audio notes with AI and turns them into clear emotion graphs, so you can actually see how you’ve been feeling over time. Record a short check-in, get the transcript, and LYLU will analyze the emotional tone of your entry across multiple dimensions such as sad–happy, anxious–calm, ashamed–proud, overwhelmed–in control, and more.
