Write to Your Future Self,
One Email at a Time
OhDiary helps you keep a future-self journal without adding another app to your routine. Get a daily email prompt, reply with your entry, and receive memory flashbacks from your past self.
How Future-Self Journaling Works
A simple loop you can stick with every day.
Daily Prompt
You receive a journaling email each day at the exact time you choose.
Reply to Journal
Reply straight from your inbox. No extra app, no friction.
Get Memories Back
Read entries from 1, 3, or 5 years ago and reflect on how far you've come.
Why this works better
The inbox-native habit means you already check email daily—no new app to remember. Prompts arrive automatically to keep you accountable, and future-self memory flashbacks make the habit deeply rewarding over time.
Private by default
Your journal stays completely private and encrypted. Passwordless magic links reduce friction and improve security, and you can export all your entries anytime.
Future-Self Journaling FAQ
Is this like writing an email to my future self?
Yes. OhDiary is designed around that behavior, but as a continuous daily habit instead of a one-time letter.
How often do memory emails show up?
When applicable, your daily email includes entries from the same date in previous years—for example 1, 3, or 5 years ago.
Do I need to install an app?
No. You can journal by replying to email. OhDiary also has a web interface when you want to browse, search, and reflect.
