AI Journal & Mood Tracker
Jot it down.
It becomes your journal.
Mood and tags, automatic.
Emopi Diary is a journal you write with AI. Jot down a few words whenever something comes to mind, and AI shapes them into today’s entry — with mood, energy, and topic tags added automatically. Journal text is stored encrypted.
FEATURES
Write a little each day,and look back on how you felt.
Shown in the same screens as the real app. The content is sample data.
Write
Write things down as they come, and get a natural entry
Post short notes in whatever order they come to mind. AI sends a brief reply and turns your scattered notes into today’s entry right away. Putting it all together is AI’s job, so you can write whenever you like.
Digest
AI writes your journal as you jot down notes
AI compiles your notes into today’s entry. Keep the summary as is, ask AI to rewrite it, or edit it yourself. You can also write entries entirely in your own words.
Mood
Pick words that fit how you feel today
Instead of AI’s estimate, choose up to three feeling words from the mood wheel, and record the mix that fits with colors and gradients.
Insights
See today’s mood and energy at a glance
From your journal, AI estimates the day’s mood as a mix of feeling words with percentages and your energy from 0 to 100%. Topic tags and charts show how your days shift.
Records
Look back on your days from the calendar
Each day’s mood colors your calendar. Tap any date or topic tag to open past entries anytime and follow the rhythm of your days.
PRIVACY
Keep your journal textencrypted and private.
Your entries are encrypted with a dedicated key and never shared with anyone. They are never used to train AI.
Stored encrypted
Journal text is stored encrypted and is never kept as plain text in the database, keeping your daily records safe.
Not visible to others
Your journal text and your exchanges with AI are never visible to other users or third parties.
AI on your terms
AI processing is based on your consent, and you can withdraw it at any time. Your past records remain safe, and you can keep writing in your own words.

FAQ
Frequently asked questions
Can the Emopi team or AI read my journal?
Journal text is stored encrypted. AI processes it to write digests and analysis, based on your consent, and we do not routinely read the text. You can withdraw the consent at any time — your records stay, and you can keep writing in your own words.
Can I edit what AI wrote?
Yes. Whether to keep a digest as is or have it rewritten is always your call, and you can also rewrite it in your own words.
How far does the free plan go?
Writing works the same on both plans. On Free, AI works up to a set amount, and topic tags and the timeline cover the last 3 days. With Emopi Diary Plus, more AI summaries are available and the look-back covers every entry.
How is it different from Emopi?
Emopi is an app for connecting with someone you care about and sharing how you are doing. Emopi Diary is a journal you keep for yourself. They share one account, and what you write in Diary is never shared through Emopi on its own — sharing happens only when you choose it there.
Is it a replacement for medical care or counseling?
No. Emopi Diary does not provide diagnosis, treatment, counseling, or emergency response. If you are unwell for a prolonged period, please consult a healthcare provider or a professional support line.
