What it does
Small, kind tools for a busy head.
Lumi helps you notice a heavy thought, check it and set it down. Here’s what’s inside.
Lumi’s edit
Watch a heavy thought get lighter.
Type the thought the way it sounds in your head. Lumi edits it with you, right on the page: she strikes the word that isn’t fair, writes a truer one above it, and the sentence lets its breath out.
Six ways of looking, from Check the words to Fact or guess. One edit of your own thoughts a day is free.
Today’s thought
One shared thought a day.
Everyone gets the same thought each day. Tap the words that aren’t quite true, pick the honest swap, then share your squares. There’s nothing personal in them.

Worry on ice
Tools for hard moments
Quiet help when it’s hard.
Breathe with Lumi, ground yourself through your senses, use TIPP when your body is racing, or put a worry on ice until later. In a hard moment the app goes quiet: short words, calm colour, one thing at a time, and Talk to someone in the corner of every screen.
Free, always. Never part of Pro.
Learn
Short episodes you can touch.
Lumi explains how things like anxiety work, in a few minutes you tap through rather than read. Ride one wave with her and watch how it rises, peaks and falls.
A new episode each day.
Talk to Lumi
Someone to think out loud with.
Tell Lumi what’s on your mind, big or small. She listens, asks gently, and can point you to a tool that fits. She’s a companion, not a therapist.
Three chats a day are free.
Your week, edited
Your week, as a story.
Each week becomes a few short slides: what Lumi noticed, the words you retired, what helped, and one thing to try next. It’s made from labels and counts, never your journal text.
Your first one is free.
The Lumi Promise
Four things we won’t change.
We say them here, in the app and on the paywall, so you can hold us to them.
Help in a hard moment is free, forever.
Everything that helps when it’s hard stays out of Pro, and a hard moment never gets a sales pitch.
Never behind Pro
- Help in a hard moment
- Breathing
- Worry on ice
- Grounding
- TIPP
- Check-ins
- Your journal
Your journal stays on your phone.
Your entries, moods and check-ins live on your device, and we can’t read them. Lock the app with a PIN, or with your face or fingerprint.
No ads and no analytics.
Nothing in the app tracks what you do or who you are, and we never sell your data. Pro is how Lumi pays its way.
No streaks to lose.
Miss a day, or a month, and nothing breaks. Your jar fills with moments instead of counting days.
Privacy, plainly
Your words stay yours.
The AI only sees the words you ask it to work on.
Ask Lumi to edit a thought and the AI gets that thought and the mood you picked. Your journal isn’t sent.
Nothing you write is stored on our servers.
Your words pass through to the AI and back. We keep only what sign-in needs, and a count of the edits and chats you’ve used.
You don’t need an account to journal.
Journaling, check-ins and the tools work without signing in. You only sign in, with Apple or Google, for the AI features.
Sent to the AI
- “I always get things wrong.”
- Mood: anxious
Stays on your phone
- Your journal
- Your check-ins
- Your other thoughts
With it goes a scrambled account reference, never your name or email, so the provider can spot misuse. None of it is kept on our servers, and neither AI provider trains on it.
Free and Pro
Free where it counts. Pro when you want more.
Everything that helps in a hard moment stays free. Pro is for going further on a good day.
