Glacifier: AI Journal & Diary

The AI journal that tells you the truth.

Most journal apps just store your words. Glacifier is an AI journal and private diary that reads what you write, remembers what keeps coming up, and tells you what's really going on, in the voice you choose. No empty praise. No generic advice.

ONE ENTRY. THREE COACHES.
Pick the tone you need today, and change it any time:
• Ruthless Coach: blunt and direct, the hard truth you've been avoiding
• Straight Facts: calm and analytical, clarity without judgment
• Pamper Mode: warm and gentle when you need kindness first

AN AI DIARY THAT REMEMBERS YOU
Ordinary diary apps forget you the moment you close them. Glacifier builds a memory of your patterns, triggers and strengths. When the same worry, habit or excuse shows up again, it notices and tells you. That is real self-reflection, not writing into the void.

WRITE, THEN TALK IT THROUGH
Write about your day, a decision or whatever is on your mind and get insight grounded in what you actually wrote. Then keep talking in chat, like a coach who has read your whole journal. Ask My Journal finds answers in your past entries.

DAILY PROMPTS FOR OVERTHINKING DAYS
Blank page? Answer a daily journal prompt that goes deeper, or tap the mic and use voice typing to talk instead of type.

MOOD TRACKER AND MOOD JOURNAL
Log how you feel with every entry. Weekly and 30-day mood charts, a mood calendar and weekday patterns show what lifts you and what drains you. Build a daily journaling habit with a streak and a plant that grows with you.

THINK THROUGH DECISIONS
Stuck on a choice? List the pros and cons and get an honest AI analysis based on what you already know about yourself.

PRIVATE DIARY WITH APP LOCK
Lock your diary with a PIN, plus fingerprint if your phone has it. Export, import and back up your journal any time.

MAKE IT YOURS
7 colour themes in light and dark.

FREE TO START
Download free and start journaling as a guest in seconds. Sign in with Google to keep your journal safe across devices. Early users who sign in get Premium free for a limited time. Premium is an optional Google Play subscription with higher AI limits; manage or cancel any time in Google Play.

WHO IT'S FOR
Anyone who wants a journal that does more than collect dust: stress and overthinking, self-improvement, habit building, career and life decisions, gratitude and daily self-reflection.

YOUR DATA
Your entries are stored in your account, encrypted in transit and at rest. Glacifier is not end-to-end encrypted: to write replies, your text is sent to our AI providers (OpenAI and Anthropic), who do not use it to train their models. We don't read your journal, and access to our database is limited and logged. Your diary is never sold or used for ads. Delete entries, or your whole account, in the app at any time.

Glacifier is still growing, so you may find a few bugs, and its AI can make mistakes. Please double-check anything important.

A note on wellbeing: Glacifier is a self-reflection tool, not a substitute for professional mental-health care. If you are in crisis, please contact your local emergency number or a crisis helpline.
