How ToSelf works

ToSelf is a journaling app that turns your writing into data that you can use to observe patterns, learn about what's on your mind, and reflect.

ToSelf extracts keywords, sentiment, and emotions expressed from what you write, and allows you to explore the data through beautiful visualizations. The more you write, the more there is to notice.

Write and organize your thoughts

Work things out, express what's on your mind, and keep track of things in a clean, intuitive writing interface. Organize messages into threads to keep trains of thought separate.

A digital journal built for
self-reflection

With journaling normally you would have to reread every different text to get a gauge on moods and patterns. Whereas this shows you all the data at your fingertips. Just go there and see what the writing patterns were like.

Daniel, MI
I didn't realize how much of a pattern there is using certain words. I enjoyed seeing that about myself and also how it puts a mirror to your thought patterns.

Demetrius, OH
It gave me insight into my emotional tone and showed me the words I tend to use most often. It was a gentle way to learn about myself without judgment.
