AI Journal & Diary CAIRN PRO

The journal that cannot read your journal. Write or speak, reflect with a warm AI companion, and watch your patterns surface. Encrypted on your device.

CAIRN is a private journal with a warm AI companion. Write or speak about your day, reflect with a thoughtful listener, and notice the patterns you could not see on your own. Your entries are encrypted and stay on your device.

Private by Design:

• Entries are stored on your device and encrypted at rest.
• Lock everything behind Face ID, Touch ID, or a passcode.
• There is no app server. AI requests go directly from your device to Anthropic, never through us.
• Your reflections are not used to train AI models by default.

A Warm AI Companion:

• Reflects back what you wrote and validates how you feel.
• Asks one good open question instead of piling on advice.
• Choose a tone that fits you: listener, stoic, socratic, coach, or friend.
• Adjust warmth and length so it sounds the way you want.

Mood and Emotion Tracking:

• Capture how you feel with a two-axis pad for pleasantness and energy.
• Name precise feelings with a curated emotion vocabulary.
• Log a check-in in seconds, with or without writing.

Insights and Patterns:

• Weekly and monthly AI reflections that surface recurring themes.
• Pattern detection, such as moods that tend to dip on certain days.
• A private year-in-review of the arcs you lived through.

Ask Your Journal:

• Ask questions about your own past, like when you last felt proud.
• Get answers drawn from your entries, retrieved on your device.

Voice Journaling:

• Speak instead of type, transcribed on your device.

Guided Templates and Prompts:

• Gratitude, CBT thought record, decision journal, dream journal, and daily reflection.
• Daily prompts plus a prompt library and curated packs.

Kind Habits:

• Forgiving streaks that encourage you without guilt.
• Calendar heatmap, on this day memories, and full-text search.
• Gentle reminders you control.

You Own Everything:

• Export to Markdown or PDF anytime.
• Encrypted backup and restore, plus a clean therapist-export PDF.
• No lock-in. No ads, ever.

CAIRN is a journaling companion, not therapy, medical advice, or a crisis service. It complements professional care and is not a substitute for it.

Journaling is free forever. Pro unlocks the AI features with a monthly plan, an annual plan, or a one-time lifetime unlock.
