What is Lume?
Lume is an AI-powered journaling and mood-tracking app. Instead of a blank page, you get prompts and real-time replies from smart personas. Every post lives in a private feed, making reflection feel as natural as scrolling social media—only healthier.
How do I use Lume?
You can write freely, use your voice, or share text from other apps. After you post, AI personas respond with insights, reflections, or supportive thoughts. You can reply back to keep the conversation going.
It’s designed to feel natural — just open the app and write one thought. That’s enough.
What are the AI personas?
Each persona offers a different lens:
- Therapist – gentle, validating, and trauma-informed
- Stoic – calm, grounded, focused on what you can control
- Playful – lighthearted and encouraging
- Time Traveler – offers future or past perspectives
- Realist – practical and straightforward
- Christian / Buddhist / Muslim – spiritual reflections based on your faith
- Lume – the app’s default, observant and warm
You can switch personas any time.
Is it private?
Yes. Your data is encrypted and never shared. You’re in control of what’s stored and synced. Lume is built for self-reflection, not surveillance.
What does the mood calendar do?
Lume automatically detects the mood of each post and displays it on a calendar. You can tap any day to see what you wrote and how you felt.
There are two views:
- Daily – one mood per day
- Per Post – multiple moods if you post several times a day
You can update moods manually too.
Which integrations are available?
- Health Connect pulls steps and workouts into your journal.
- Phone usage logs screen-time totals.
- Browser extension (Chrome & Firefox) captures your top domains.
- All data rolls into Insights for richer self-reflection.
What are “Insights”?
Insights are summaries, trends, and answers based on your journal.
You can:
- Generate a daily summary of your mood, habits, and reflections
- Ask questions like “When do I feel most energized?” or “What changed last week?”
- See a wellness report based on your steps, activity, and sleep
Can I customize reminders?
Yes. You can get up to three daily nudges to reflect — by default at 7am, 2pm, and 7pm. You can change or disable them anytime in settings.
We also send smart notifications after your first post to encourage deeper reflection.
What happens if I stop journaling?
Lume gently reminds you, but never nags. You can always pick up where you left off. You won’t lose your data, your streak, or your insights.
Is Lume free?
Yes, Lume is free to use.
What’s the best way to get started?
Just open the app and write one thought. Or respond to a suggestion in your feed. You don’t need a plan — just a moment of honesty.
New users get a special message after 3 posts that unlocks a daily summary. That’s a great goal to aim for.
