Sintera: AI Journal & Diary

Sintera is an AI journaling app that helps you see the patterns that repeat in your life — the recurring thoughts, emotions, decisions, and blind spots that shape your days.

Start with what's on your mind. No perfect prompt needed. When you finish an entry, Sintera reads it in context and reflects it back: a clear summary, the patterns it connects to, and questions worth sitting with.

WRITE FIRST
• A calm, focused editor built for real writing
• Voice notes that become text instantly
• Add photos to keep the full memory

FINISH TO SEE WHAT COMES BACK
• A thoughtful analysis of each entry
• Quotes and reflections drawn from your own words
• Prompts that connect today's entry to what you wrote before

SEE YOUR PATTERNS
• Sintera scans your journal to find the loops that keep showing up
• Understand triggers and blind spots across weeks and months
• Deepen with guided AI coaches that remember your context

PRIVATE BY DESIGN
• Entries are encrypted in transit and at rest
• AI insights are generated securely on the server
• Delete your account and your data anytime, right from the app

Sintera Premium unlocks entry analysis, pattern detection, AI coaches, and voice-to-text journaling. Subscriptions renew automatically unless canceled at least 24 hours before the end of the current period. Manage or cancel anytime in your App Store settings.
