Voice-first diary AI mood tracking

Speak your day.
Let LYLU turn it into an emotional diary.

LYLU is a daily audio diary: record short voice notes, get instant transcription, and see how your emotions shift over time across multiple dimensions – from sad ↔ happy to overwhelmed ↔ in control.

Free tier for quick daily check-ins • LYLU Pro for longer, higher-quality recordings (up to 10 minutes each).

Daily AI mood snapshots

From voice to emotional timeline in three steps

LYLU keeps things simple: talk, transcribe, track. Entries are always mapped to the day they were recorded, so your diary stays naturally chronological.

1 Record

Speak instead of typing

Open LYLU, hold the mic, and talk about your day. Each recording is linked to today’s date, so you never have to name or organize entries manually.

2 Transcribe

High-quality AI transcription

Your audio is transcribed using modern speech-to-text models. In LYLU Pro you can transcribe longer audios (up to 10 minutes) with better quality and speed.

3 Track

See your mood in motion

Every transcript is analyzed for emotion. LYLU aggregates entries per day and shows you clear graphs of how your emotional patterns evolve over days, weeks, and months.

Five emotional pairs to describe your day

LYLU doesn’t flatten your mood to a single number. Each entry is evaluated along complementary emotional pairs, giving you a more nuanced snapshot of how you actually felt.

Sad Happy
Anxious Calm
Angry Content
Shame Pride
Overwhelmed In control

Where did this entry land today?

In addition to the pairs, LYLU places each entry in a classic polarity vs. arousal map: from negative to positive and from low-energy to high-energy. Every recording becomes a point in this space.

A quick glance at emotional intensity

Each transcription is reduced to a coordinate: how positive it was and how intense it felt. Over time, the points form a cloud that tells you whether your days tend to be calm and balanced, or high-energy and volatile.

This view complements the five pair-based graphs, so you can interpret subtle shifts: a “happy but exhausted” evening vs. a “calm but low” Sunday, for example.
