Secure, private, and automatic organization of your thoughts.
I created this app because I'm terrible at journaling. Hansei makes journaling frictionless: Just say what's on your mind or type your thoughts, and in seconds your entry is securely transcribed by your own device, then automatically tagged and organized into a dynamic growing knowledge graph of your thoughts.
For iPhone 15 Pro and later.
Your best thinking happens at the wrong time.
In the car. After a meeting. Right before sleep. The Action Button captures it in seconds — no unlocking, no typing, no friction.
One press. That's it.
Press the Action Button and speak. Hansei transcribes 100% locally on your device, tags the people/ideas/things in your entries, and files it away. Your hands stay free.
A private analyst that knows your whole story.
Hansei reads across everything you've recorded and surfaces what you'd otherwise miss.
- You've mentioned the Henderson project feeling stuck three times this week.
- Your energy is consistently lower on days after late calls.
- You keep coming back to the idea of simplifying your morning.
The analyst runs entirely on your device. Nothing leaves your phone.
While you sleep, it connects the dots.
Hansei processes your entries overnight, finding patterns across days and weeks. By morning, you have a clearer picture of what's actually going on.
Priorities that reflect your life, not a template.
The analyst suggests priorities based on what you actually talk about — then you decide. Edit them, ignore them, or let them guide your next debrief.
On-device. Always.
Speech recognition, tagging, and analysis all run on your iPhone. Nothing is sent to a server, no account is required, and there is nothing to track.
Optional iCloud sync encrypts your journal on your device before it ever leaves.

Hansei is a Japanese practice of honest self-reflection — examining what happened, what you learned, and what you'd do differently. It's how pilots stay sharp. It's how you stay clear.
