AI Journal & Mood Tracker
Notes become a diary.
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.

Write it like a quick note
Jot something down whenever it comes to mind. AI replies, and the words keep coming.
Digest
Today’s entry builds as you write
Whether to keep it as is or have it rewritten is always your call — and you can also write in your own words.

Keep AI’s read, or re-pick it from the wheel. Sometimes a feeling you could not name finds its word there.

FAQ
Questions,quietly answered.
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.
