An AI journaling app for iOS, Android, and web that helps you write, deepen, and revisit your thoughts to surface recurring patterns and blind spots over time.

About

Homepage of Sintera

Sintera is an AI reflection app designed to help you understand patterns in your thoughts, emotions, and decisions. You write about what's on your mind, then use guided reflection tools called coaches to deepen your thinking. Once you finalize an entry, Sintera analyzes it to surface recurring patterns, emotional breakdowns, and personalized follow-up questions drawn from your own words.

Unlike a simple journal or chatbot, Sintera connects your entries over time, helping you see what keeps repeating and why. The app provides pattern insights, visual outputs, and re-entry prompts to help each new reflection build on the last. Available on the web, iPhone, iPad, and soon Android, Sintera keeps all writing encrypted and protected while processing AI analysis securely on the server.

Quick answers

Isn't this just an AI journal?
Sintera does more than store entries. It connects finished reflections over time and helps you see what keeps returning, unlike a standard journal.
Why use Sintera instead of ChatGPT?
ChatGPT helps with single conversations, but Sintera keeps context across entries and returns insight from patterns that repeat over time.
Will AI replace my voice?
No. Your writing stays the starting point. Sintera helps you notice more in what you wrote, not speak for you.
Can I use Sintera on my phone?
Yes. Sintera is on the App Store for iPhone and iPad, the web app works in any modern browser with the same account, and the Android app is in active development.
How is my writing protected?
Your writing is encrypted in transit and at rest. Sintera generates AI insight securely on the server, and full data-handling details are in the Privacy Policy.
