Mind Journal: AI Diary & Lock

Mind Journal is a private diary with lock and a daily journal app with PIN and fingerprint protection, a mood tracker and an optional AI assistant. Keep your personal diary, a gratitude journal, a travel diary or a dream journal, and look back on your life. It works offline, and you can write in any language. DIARY WITH LOCK Your diary is yours alone. • Lock the whole app with a PIN or fingerprint • Lock individual journals with their own PIN • Pages in locked journals stay out of search, statistics, reminders and AI while they are locked • Start writing without an account DAILY JOURNAL, YOUR WAY • Create separate journals: personal diary, work journal, travel diary, private notebook or anything else • 10 paper styles: blank, ruled notebook, lined paper, vintage parchment, botanical, dot grid and more • Add photos, change fonts and format your text • Add a mood to any entry • Write in English, Bangla, Hindi, Arabic or any language you prefer • Dictate entries with your voice • App language: English, Bangla, Hindi and Spanish MOOD TRACKER & MOOD CALENDAR See your mood history, writing streak, word count and journal activity. Use the mood calendar to look back at how different days and months felt. "On this day" brings back past diary entries you may have forgotten. AI JOURNAL ASSISTANT (OPTIONAL) AI is optional. Ask Mira, your journaling companion, about your own diary: • "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?" Mira can summarize a month, review the last few weeks, and help you notice good moments, difficult periods and recurring themes. Turn what you notice into goals and follow your progress. AI writing tools can also fix grammar, shorten text or turn rough notes into clearer sentences. To answer, the text needed for your request is sent securely to our AI provider. It is not used to train AI models or for advertising. Locked journals are not used by the AI.
