Capture the day
Write as much or as little as you want.
Private journal · Local AI
Write a little.
Talk when you want.
Keep the day in your own words. When you want another perspective, talk with the entry you chose.
Write and browse without an account. Your original entry stays close.
A journal first
One line is enough.
Moirion begins as a simple place for moods, moments, ideas, and the details you do not want to lose. AI remains a second layer, available only when it helps.
Find it again
Browse your journal without digging through a feed.
Keep your words
Your original stays separate from summaries and replies.
When you want to talk
The AI begins with your entry.
Choose something you wrote and ask naturally. Moirion keeps the reply close to that journal entry instead of turning the app into a general chatbot.
Choose an entry
Open a day or moment you want to revisit.
Ask naturally
Ask what helped, how you felt, or simply ask it to listen.
Return to your words
Open the current original whenever exact wording matters.
On your Mac
Private by default.
Writing, browsing, and opening an original entry work without a cloud account. AI conversation can run through a compatible model installed on your Mac.

Before you start
Common questions.
What is Moirion?
Moirion is a lightweight private journal. Write first, then use local AI to talk with a day or entry when you want to revisit it.
Do I need an account?
No. You can start using Moirion locally without creating an account.
Does my data leave my computer?
Not by default. Your notes stay on your machine unless you choose to export, upload, or connect something.
Do I need a local model before I start?
No. Writing, archiving, and opening originals work first. Conversation requires a compatible model available on your Mac.
Which local models are supported?
Gemma and Qwen are part of current local testing. Model quality and speed vary by hardware and model size.
Is the iPhone app available?
Not publicly yet. The app is running in Simulator, while physical-device validation and TestFlight release remain in progress.
