Peter Theill

Founder and developer, passionate about helping people document their lives. A dedicated journaler who hasn't missed a day in over 14 years, turning personal practice into a platform that serves thousands.

OhDiary began with a simple idea: make journaling effortless and meaningful. With OhDiary, you write private reflections on your daily experiences through a gentle email reminder system.

The beauty is in the simplicity—write as much or as little as you want. Just keep the momentum going. Years later, when you receive an email reminding you of what you wrote on a specific date, you'll experience the joy of rediscovering your past self.

After more than a decade of helping thousands document their lives, we remain committed to privacy, simplicity, and the profound impact of consistent journaling.
