Mind Journal: AI Diary & Lock

Mind Journal: AI Diary with Lock is an AI-powered journaling app that gives you a private, offline place to write daily notes, track moods, look back on your life, and understand your journal with AI when you choose to use it.

Write a daily journal, keep personal notes, track your mood, add photos, and protect your diary with a PIN or fingerprint. Mind Journal works offline, while AI and cloud backup are optional.

You do the writing. There are no forced daily prompts and no AI constantly asking about your day. The AI stays out of the way until you ask for it.

KEEP A DIARY YOUR WAY
Create separate journals for different parts of your life — a personal diary, work journal, travel diary, private notebook, or anything else you want to remember.

Make each journal your own:
• Choose from 10 paper styles
• Add photos to your entries
• Change fonts and formatting
• Add a mood to any entry
• Write in English, Bangla, Hindi, Arabic, or any language you prefer

KEEP PRIVATE THOUGHTS PRIVATE
Protect the entire app with a PIN, or lock individual journals separately. You can also use fingerprint unlock for quick access.

Locked journals stay out of search, statistics, reminders, and AI access while locked.

ASK YOUR OWN JOURNAL
Sometimes the answer you're looking for is already somewhere in your diary.
When you ask, the AI can use your journal entries to answer questions about what you've written.

Try questions like:
• “When did I last see the dentist?”
• “What did I spend most of my time on last week?”
• “How was March?”
• “What have I been writing about lately?”

Instead of scrolling through months of old entries, simply ask.

The AI can also summarize a month or review the last few weeks to help you notice recurring themes, good moments, difficult periods, and things you may want to work on.

Turn those reflections into goals and follow your progress through your journal. AI writing tools can also fix grammar, shorten text, or turn rough notes into clearer sentences.

Your locked journals are not used by the AI.

TRACK YOUR MOOD & MEMORIES
See your writing streak, word count, journal activity, and mood history. Use the mood calendar to look back at how different days and months felt.

“On this day” brings back past entries so you can rediscover moments you may have forgotten.

WORKS OFFLINE
You don't need an internet connection just to write.
Create entries, browse journals, add moods, search your writing, and use core diary features offline. AI and cloud features are optional.

BACKUP, SYNC & EXPORT
Turn on cloud backup to keep supported journal data backed up and available across your devices.

You can also:
• Export a page or journal as PDF
• Save an entry as an image
• Keep copies of important memories outside the app
Cloud backup and sync are available with Premium.

REMINDERS — ONLY IF YOU WANT THEM
Turn on an optional nightly writing reminder, and Mind Journal can skip it when you've already written that day. You can also enable a weekly recap to look back at your week.
