About
Remember your life without turning journaling into homework.
OneLine is a private daily journal built for people who want to capture more of life with less effort.
Write one honest line about your day, add your mood, record a thought with your voice when you want, and move on. Over time, those tiny entries become something bigger: a personal record you can revisit through memories, AI-powered stories, reflections and patterns.
WRITE LESS. REMEMBER MORE.
• One-line journaling — capture your day in seconds instead of writing long diary entries.
• AI stories & memories — turn everyday moments into stories and memories worth revisiting.
• Mood insights — look back at how your days and emotions change over time.
• Voice journaling — capture a thought when speaking feels easier than typing.
• Rewind memories — rediscover moments you might otherwise forget.
• Guided prompts — get a little inspiration when you don't know what to write.
• Offline capture — save your thoughts even when you're not connected.
• Private Vault — keep selected entries in an optional encrypted space.
NO PRESSURE TO PERFORM
No public feed. No essays. No need to make every day profound.
Miss a day? Come back tomorrow.
OneLine is designed to make journaling light enough to actually keep doing — while quietly building a record of the moods, thoughts and moments that make up your life.
A few seconds today. A life you can look back on tomorrow.
Your everyday moments are easy to lose. OneLine helps you keep them — one line at a time.
